Volcano activity increasing worldwide

         Volcano activity increasing worldwide


March 27, 2012  Volcanoes around the world are showing an increase in activity again.
Here is the overview of last 24 – 48 hours of recorded activity, indepth analisys will be made after all reports come in. 6 volcano updates since March 25.

Popocatepétl volcano (Mexico): signs of increasing activity
Popocatepétl volcano in Mexico has been showing signs of increased activity. During 24-25 March, the volcano had 33 small steam and gas emissions, accompanied by small earthquakes and volcanic tremor. On Saturday night, incandescence was observed at the crater.

Popocatépetl, whose name is the Aztec word for smoking mountain, towers to 5426 m 70 km SE of Mexico City to form North America’s 2nd-highest volcano. The glacier-clad stratovolcano contains a steep-walled, 400 x 600 m wide crater.

Batu Tara volcano (Indonesia): larger ash eruption
Volcano Batu Tara in the Sunda Sea off the island of Flores in Indonesia had a larger than usual ash eruption on March 26, which triggered an alert of the VAAC Darwin, who raised the aviation color code to “orange”, as the drifting ash cloud is be a hazard to local air traffic.
Batu Tara is one of the most active volcanoes in Indonesia and is characterized, similar to Stromboli volcano, by semi-permanent explosive summit activity.

Until 2006, the only confirmed historical eruption from Batu Tara were during 1847-52, which produced explosions with volcanic bombs and a lava flow. On July 1st, 2006, Batu Tara was observed erupting again.
An ash plume rose to 5000 ft (ca 2 km). Since then, it has been erupting frequently. Most eruptions were strombolian or vulcanian type, with explosions producing ash plumes of 1-2 km, similar to Anak Krakatau’s activity.
In March 2007, a phase of stronger eruptions promted the evacuation of 15000 people from Lembata Island nearby.

Tungurahua volcano (Ecuador): constant ash emissions and ash fall
Eruptive column above Tungurahua volcano reaching about 2 km height and heading towards the northeast was reported on March 26.
Tungurahua volcano’s activity has been increasing, Ecuador’s Instituto Geofísico reports. Throughout the morning of March 26, a constant column of steam and ash was rising from the summit crater, reaching up to 3 km height and drifting towards the northeast, where ash fall occurred.

Ash fall was significant in the San Francisco and Black River areas, and mild in Baños, the Ventanas en Runtún, Juive, Pondoa, Puntzán and Cusúa sectors.
Occasional roaring explosion sounds were heard from small to moderate explosive events. Seismic activity remains characterized by volcanic tremor episodes lasting several minutes, interspersed with tremor bursts and long-period events, which are related to fluid movements within the volcano.

Santiaguito volcano (Guatemala): increased activity
Guatemalan volcano Santiaguito increased activity. The authorities on March 26th took all the necessary precautions with the surrounding air traffic. The dispersion of ash in various directions and changes in wind pattern led to the National Institute of Seismology, Volcanology, Meteorology and Hydrology (Insivumeh) to warn about the civil aviation.

An Insivumeh report that Santiaguito volcano recorded 33 explosions in 24 hours, with a range of up to 800 meters above the crater, leaving ashes scattered in the southwest and southeast.
Santiaguito volcano is located in Quetzaltenango district, and its height is 2,550 meters above sea level.

The massive dacitic Santiaguito lava-dome complex has been growing at the base of the 1902 crater since 1922. Compound dome growth at Santiaguito has occurred episodically from four westward-younging vents, the most recent of which is Caliente. Dome growth has been accompanied by almost continuous minor explosions, with periodic lava extrusion, larger explosions, pyroclastic flows, and lahars.

Fuego (Guatemala): increased activity
Guatemalan volcano Fuego (fire) also increased activity. Authorities took all the necessary precautions with the surrounding air traffic. The Insivumeh reported white and blue plume up to 100 meters above the crater, with displacement to the southwest, in the case of Fuego volcano, whose height is 3,763 meters above sea level and is located between the departments of Sacatepequez, Chimaltenango and Escuintla (center south).

Volcano Fuego is one of Central America’s most active volcanoes. It’s one of three large stratovolcanoes overlooking Guatemala’s former capital, Antigua. The scarp of an older edifice, Meseta, lies between 3763-m-high Fuego and its twin volcano to the north, Acatenango.

Lamington (Papua New Guinea): smoke and ash emission
Local community of Popendetta reported smoke and ash emission on March 25. No official reports have come in yet. Lamington is an andesitic stratovolcano with a 1.3-km-wide breached summit crater containing a lava dome.

After a long quiescent period, the volcano sprang suddenly to life in 1951, producing a powerful explosive eruption during which devastating pyroclastic flows and surges swept all sides of the volcano, killing nearly 3000 persons. The eruption concluded with growth of a 560-m-high lava dome in the summit crater.
Some reports of 1951 eruption say that not enough percautions were taken and it led to many casualties.

New Zealand Taupo super-eruption secrets revealed
April 27, 2012 -  One of the most intriguing unsolved cases for New Zealand geologists is the ancient Taupo super-eruption.
Victoria University PhD student Aidan Allan has found new evidence that explains how and why the volcano blew.

While the general public is fascinated by the magnitude – the event buried the North Island in debris, with the ash cloud all the way to the Chathams – geologists' interest lies elsewhere.
They are intrigued because the eruption's cause isn't open-and-shut – while most super-volcanoes simply explode, with Taupo there was a short hiatus just as things got underway.

"There were breaks of weeks to months [in the early stages] and then all hell breaks loose," Mr Allan said.
As geologists worldwide have to make the life-or-death call as to when an eruption has ended, it's crucial to know why this super-volcano acted the way it did.

Russian Shiveluch volcano spews ash 10.7km above sea level
Apr 26, 2012  ANI  Itar-Tass  The Shiveluch volcano on Russia's Far Eastern Kamchatka Peninsula ejected an ash cloud to as high as nearly 11km above the sea level.
An ash column from the volcano rose to a height of 10.7km above the sea level.

There was no immediate threat for the population, and no emissions of volcanic dust were monitored in neighboring villages.
Two earthquakes were registered at the volcano over the past 24 hours, which was given the highest Red Aviation Code.

This was the most powerful eruption of ash registered at Shiveluch this year. Shiveluch has been active for more than four weeks.
Shiveluch, standing 3,283 meters above the sea level, is Kamchatka's northernmost active volcano.

Nicaragua Monitors Microseismic Activity Increase in Volcano
Managua, Apr 29  Nicaraguan Experts reported Sunday more seismic activity at Masaya volcano, about 20 kilometers south of Managua, with an increase in expulsions of sulfur gases, which keeps the disaster warning system in high alert.

According to the report, a crack in the main crater causes higher emissions and a sound similar to a jet engine.
Specialists of the National System for Prevention, Mitigation and Attention to Disasters (SINAPRED) and the Nicaraguan Institute of Territorial Studies (INETER), told the press that they detected this unusual behavior several days ago, but for now there is no reason for alarm.

Rising emissions and temperature above the normal range.
Technical teams assess the seismic tremor, but there is no emergency declared and the gates of Masaya Volcano National Park remain open to the public, said the director of INETER, Jorge Castro, and the executive secretary of SINAPRED, Guillermo Gonzalez.

Indonesia Mt Lokon erupts again
May 1, 2012  Jakarta  Mount Lokon volcano in North Sulawesi erupted again at 11:55 a.m. local time on Tuesday.
The latest eruption was larger in magnitude compared to the eruption last Wednesday but local residents were more prepared.
The eruption was preceded by a number of mild earthquakes over a span of two minutes.

National Disaster Mitigation Agency (BNPB) spokesman Sutopo Purwo Nugroho said smoke plumes reached 2,500 meters in height when Mount Lokon erupted.
According to geologists with the Volcanology and Geological Disaster Mitigation Center (PVMBG), it is not time for residents to evacuate yet, but evacuation sites are being prepared just in case.

The BNPB has deployed a team to keep the situation in Mount Lokon under control. The agency has also prepared transport, Rp 400 million (US$43,600) in cash and other equipment.
Other emergency teams are on stand-by in Malang’s Abdul Rahman Saleh Airport with Hercules C-130 aircraft ready for evacuation. “Everything is ready,” Sutopo said. (nat/swd)

Indonesia Mt Merapi enters preparation phase before eruption: Expert
May 1, 2012  The Mt. Merapi volcano restarted its inflation process immediately after the 2010 eruption and has entered its preparation stage of a forthcoming eruption, a Japanese researcher has said.

Masako Iguchi, a researcher from the Disaster Prevention Research Institute at Kyoto University, said Tuesday that the global positioning system (GPS) installed on three Indonesian volcanoes, namely Guntur, Sinabung and Merapi, to detect their ground deformations, had signaled the inflation of Mt. Merapi.

Before the 2010 eruption, he said, Merapi had erupted in 2001 and 2006. This showed that there were some periods in which the volcano had no deformation until it inflated and the next eruption occurred on Oct. 26, 2010.
“But in this latest case, we detected that after its 2010 eruption, Merapi inflated again very quickly. This means that Merapi is a very active volcano,” Iguchi said during a meeting to present the team’s project report titled “Multi-Disciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia”.

5 Volcanoes You Should Keep Your Eye On
By OurAmazingPlanet Staff | LiveScience.com – 59 mins ago.

Italy's Mount Etna and Mexico's Popocatépetl volcano have been huffing and puffing their way into the news recently, spewing plumes of ash and dribbling lava in the latest flare-ups of eruptive activity that have been going on for years in the case of both volcanoes.

While larger eruptions, such as Indonesia's Pinatubo in 1991 and the 1980 blast of Mount St. Helens in Washington, are more famous for the disruptions they caused, some near-constant eruptions have their own associated hazard, posing threats to nearby communities and potential disruptions to air traffic from ash plumes.

Here are five volcanoes that don't always get a lot of fanfare, but have been quietly (or maybe not so quietly) rumbling and spitting up volcanic material continuously for years — even decades — in order of the number of years they've been erupting.

5. Sangay in Ecuador – 94 years

The modern volcano structure, which reaches a height of 17,158 feet (5,230 meters), dates back about 14,000 years and was built within horseshoe-shaped calderas, or volcanic depressions, of two previous edifices that collapsed and cause avalanches. The earliest report of a historical eruption here was in 1628; then more or less continuous eruptions were reported from 1728 until 1916. The volcano started up again in 1934 and hasn't stopped since.

4. Santa María, Guatemala – 101 years

Santa María is a 12,375-foot (3,772-meter) tall stratovolcano that towers over Guatemala's Pacific coastal plain. It erupted catastrophically in 1902, one of the largest eruptions of the 20th century, causing severe damage throughout southwestern Guatemala and carving a crater on the volcano's flank. A lava-dome complex, calledSantiaguito, has been forming in the crater since 1922.



3. Stromboli, Italy - 108 years

Stromboli is the tip of a massive underwater volcano that has been erupting nearly continuously for more than2,000 years. The explosive style of eruption displayed by it and other volcanoes is known as "Strombolian. A 2002 eruption caused a small tsunami and damaged a village on the island, which lies off the coasts of Italy and Sicily.

2. Mount Etna, Italy - 109 years

Dating back to 1500 B.C., the volcano has erupted around 200 times. The mountain is currently around 10,958 feet (3,340 m) high and is the largest active volcano in Europe. The most violent eruption in the history of Mount Etna occurred in March of 1669. The volcano spewed molten rock for days on end, the eruption finally stopped at the end of April that year.

1. Mount Yasur, Vanautu - 111 years

This stratovolcano is part of the archipelago nation of Vanuatu in the South Pacific.Yasur has been erupting nearly continuously for over a century, and its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian (a relatively low-level type of eruption).

Atlantic Mount Asphyxia volcano
May 2, 2012
- A plume of volcanic smoke is seen rising from the appropriately-named Mount Asphyxia volcano, located on Zavodovski Island in the southern Atlantic.
Zavodovski is part of the South Sandwich Islands, a group of 11 British-owned islands located off the tip of South America. Only 3.1 miles wide, the icy island is dominated by the 1,800-foot-high stratovolcano.

Aptly named, the sulphuric fumes from Asphyxia coupled with the stench of penguin droppings -- the island is a breeding ground for millions of chinstrap penguins -- can be suffocating for human visitors.

The plume is seen here snaking into upper-level winds where it takes a turn to the northwest. The other islands exhibit swirling cloud vortices on their lee sides, created by their disturbance of prevailing winds.

Mt. Baekdu eruption's impact on NE Asia (25)

Mt. Baekdu has been carefully observed since 1999 when a volcanic observatory was built in China, and since 2002, there have been some symptoms of an eruption.

By Park Chang-seok

Yes, one! There’s only one thing about which they think in a same way – a concern about possible eruption of Mt. Baekdu. The two Koreas remain at odds in everything. But they are one in voicing how to counter the possible volcanic explosion of the highest mountain in the Korean Peninsula

Inter-Korean anxiety is mounting, with growing apocalyptic predictions on the dormant volcano. A South Korean geological expert has warned that the volcano could erupt sometime around 2014 and 2015.

Former North Korean leader Kim Jong-il reportedly said people in some regions of Yanggang and North Hamgyeong Provinces were feeling anxiety over a volcanic eruption of Mt. Baekdu. Kim called for quick countermeasures by the North Korean authorities.

If a volcano, located on the border between North Korea and China erupts, damage could be 10 to 100 times greater than that caused by the April 2010 eruptions in Iceland. Experts predict that the ashes would not only hit the neighboring area but damage agriculture and cause serious disruptions in industrial activities and air flights. The Korean Peninsula, China, Japan and Russia would be severely damaged.

A volcanic eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano’s vents. When the magma chamber is completely filled, the type of eruption partly depends on the amount of gas and silica in the magma. The amount of silica determines how sticky (level of viscosity) the magma is and water provides the explosive potential of steam.

The 2010 Iceland eruption caused enormous disruption to air travel across Western and Northern Europe, although relatively small in size for volcanic eruptions. About 20 countries closed their airspace and it affected hundreds of thousands of travelers. A very high proportion of flights within, to, and from Europe were cancelled, creating the highest level of air travel disruption since the World War II.

Mexico's awakened volcano
5/3/12  Geologists warn that powerful mudflows spawned by Popocatepetl could wreak havoc.
North America's second-tallest volcano recently rumbled to life, putting authorities on edge. Big eruptions of Mexico's massive Popocatepetl volcano are "few and far between," as one geologist says. Yet even without any dramatic fireworks, 17,800-foot (5,425-meter) "Popo" has the power to wreak havoc.

Geologist Mike Sheridan, a professor emeritus at the University at Buffalo, said that Popo and, in fact, many other volcanoes around the world harbor a means of destruction that many people may not associate with volcanoes: mudflows.  
"And they don't even require an eruption, so they are less predictable," Sheridan told OurAmazingPlanet.

Popocatepetl lies about 40 miles (70 kilometers) southeast of Mexico City. The mountain reawakened in December 1994 after five decades of silence. Yet in the nearly 20 years since, the volcano has rarely exhibited the kind of vigorous activity that began the week of April 12.

Satellite spots Pacific volcano activity
May 10, 2012  Marianas are in the Philippine Sea
A NASA satellite has captured a dramatic image of steam and gas plumes from a volcano in the Mariana Islands in the Pacific Ocean, U.S. scientists said.
The image shows the activity on Pagan Island, the largest and one of the most active of the Marianas volcanoes, a NASA release reported Thursday.

Fires and smoke on the island was imaged on Tuesday by the Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Terra satellite.
Pagan Island consists of two volcanoes connected by a narrow isthmus, and almost all of the historical eruptions of Pagan dating back to the 17th century have originated from North Pagan volcano.

The largest eruption of Pagan during historical time took place in 1981 and prompted the evacuation of the sparsely populated island, NASA aid.
The Marianas are an arc-shaped archipelago consisting of the summits of fifteen volcanic mountains, anchored at its south end by the island of Guam.

High lava level reported at Kilauea volcano summit

May 16, 2012

http://www.bigislandvideonews.com...ported-at-kilauea-volcano-summit/

HAWAII VOLCANOES NATIONAL PARK, Hawaii: Scientists with the USGS Hawaiian Volcano Observatory are reporting a  relatively high lava lake level at the Halema`uma`u crater vent over the past two days, following a summit inflation at Kilauea.

Quote:
According to Tuesday’s Kilauea activity report:


The summit tiltmeter network recorded another DI deflation around 5 pm last night when the lava lake level started to drop; a laser rangefinder measurement yesterday placed the lava lake surface about 67 m (220 ft) below the Halema`uma`u Crater floor – a pretty high level.


The lava has been close to the level of the deep inner ledge. A photo released by HVO (above) shows continuous spattering at the southern lake margin tossing spatter onto the crusted lake surface as well as onto the rim of the ledge, building a steep spatter rampart (left side of image).

Satellite Spies New Lava Flow on Active Volcano

5/18/12

Bagana volcano is one of the most active in Papua New Guinea, but it is remote, and so poorly monitored.

Located on the mountainous spine of Bougainville Island, it is both far from any cities or large towns and is hard to reach due to the rough terrain around it. Satellites are the best way for volcanologists to keep an eye on the active peak, which has an elevation of 5,741 feet (1,750 meters).

The volcano emits gases (including water vapor and sulfur dioxide) almost continuously, and frequently spits up thick lava flows.

Indonesia Mount Marapi Volcano Erupts Again
5/19/12  A report, published in the Journal of Volcanology and Geothermal Research, has unveiled recently that a volcano, namely Indonesia's Mount Marapi, erupted early Friday at 7:15 a. m. local time, lasting for nearly ten minutes.

It has been found that the volcano has had several such eruptions since when its alert status was updated last August. Also, the same has erupted for a total of around 454 times since the late eighteenth century till 2008.

While a majority of these were minor eruptions, fifty of them were significant, last in the year 2005, found the team of researchers from Oregon State University.
The erupted volcano is located in the province of West Sumatra, near the cities and town of Bukittinggi, Padang Panjang and Batusangkar in West Sumatra. As per the findings, the volcano is the most active one.

It is being said that its eruptions had killed 300 people between October and November and had caused around 300,000 people to relocate as well. "Our study found some of the first evidence that the region has a much more explosive history than perhaps has been appreciated", said Morgan Salisbury, lead author.

Guatemala volcano spits lava and ash

May 19 (Reuters) - Guatemala's Fuego volcano belched burning lava and black ash into the sky early Saturday, leading the government to issue an airplane advisory and close sections of highway.

The volcano, about 25 miles (40 kilometers) southwest of the capital, erupted about 2:45 a.m. (0745 GMT), spewing a column of ash up to 16,400 feet (5,000 meters) above the crater and launching burning red lava nearly 1,300 feet (400 meters) high.

The national emergency commission issued an advisory, warning planes not to fly within a 25-mile (40 kilometer) radius of the volcano. The La Aurora international airport in Guatemala City remained open.

The commission also closed two stretches of highway threatened by lava flows that reached the base of the mountain.

Minor Glacial Burst in South Iceland Volcano Katla

A small glacial burst occurred in the volcano Katla, which lies underneath the Mýrdalsjökull icecap in south Iceland, on April 28 and lasted a few days. The activity was registered by seismic monitors and increased conduction was measured in the river Múlakvísl until May 7.

Last summer a large glacial burst, probably caused by a minor eruption in Katla, caused the river to swell and tear a hole in the Ring Road, right at the height of the tourism season in early July.

Oddur Sigurðsson, a geologist at the Icelandic Meteorological Office, told visir.is that the glacial burst in late April was so insignificant that it couldn’t be detected by the naked eye.

Oddur explained that it was caused by geothermal activity in one of Katla’s craters.

Volcano enthusiast and blogger Jón Frímann Jónsson reported on two events in Katla, on April 28 and May 6 or 7, and considers them to be warning signals: something is happening in the volcano, he predicts.

He also commented on the recent series of earthquakes which hit Herðubreið in the northeastern highlands early this week.

IndonesiaAilments Spread Among Refugees of Sirung Eruption
Jakarta Globe | May 21, 2012
Kupang. Various ailments, including coughs and other respiratory conditions, have affected hundreds of people seeking safety in temporary shelters after the eruption of Mount Sirung on Pantar island in the Eastern Nusa Tenggara District of Alor, an official said on Monday.

Mount Sirung, a 862-meter-high volcano, erupted on May 13, forcing some 250 people from the Mauta village on its slope to seek safety elsewhere in the district.
The volcano was put on the third level of alert after it began to show increased activity on May 8.

“Residents are beginning to be affected by ailments such as coughs, sneezing, and other respiratory conditions,” Viktor Tanghana, the head of the Alor district Disaster Mitigation Office said.
Viktor said children were the most vulnerable among the displaced.

He said the district had already deployed a medical team to the temporary shelters to provide some help, and the authorities had also sent food aid such as rice, corn and instant noodles and cans of sardines.
The evacuation of Mauta, approximately 300 meters from the crater, was conducted by the local authorities at the request of the Vulcanology and Geology Disaster Mitigation Center in Bandung (PVMBG), Viktor said.

He said although the people of the village had been evacuated to the temporary shelters, they continued to return to their fields to work.
Viktor also berated the shortage of face masks at the district level, and called on the disaster mitigation office in Kupang, the provincial capital to send at least 500 such masks to the district for distribution.

JAPAN  High possibility of Mt. Fuji’s eruption
May 20th, 2012   Professor Emeritus, Kimura from Ryukyu university warns eruption of Mt. Fuji in 3 years is the bigger risk than possible earthquake caused by the active fault.  He points out these 2 facts below

1. From North east to South west of the crater, water eruption is observed. This is the water version of eruption instead of magma,but the mechanism is almost the same as normal eruption. In Fujinomiya city beside Mt. Fuji, water has been springing every few months since 2 years ago. Water level became higher all of a sudden at Fujigoko lake located at North to Mt. Fuji.

2. Huge holes appear in the Fuji maneuvering ground of Japanese Self Defense Force. Natural gas is coming up from the holes. The temperature is 40℃ ~ 50℃. It is not the volcanic gas directly coming up from magma but considering water eruption as well, it is highly likely to be the omen of major eruption.

According to the simulation of Cabinet Government, volcanic ash will be accumulated 2~10cm even in Tokyo, where is 100km away from Mt. Fuji. In the worst case, 14,600km of road will be closed. 515 flights will be cancelled a day. 1,080,000 houses will be out of power. The estimated economical damage will be 2 trillion and 500 billion yen.

Is an eruption at Costa Rica’s Turrialba Volcano imminent?

Posted: Sunday, May 20, 2012 - By Clayton R. Norman

Costa Rica’s National Seismological Network has upgraded the color threat level to yellow of Turrialba Volcano, in the province of Cartago east of the capital.

A statement issued by Raúl Mora-Amador, coordinator of Seismology, Volcanology and Geophysical Exploration at the University of Costa Rica, indicates a threat level of yellow means that the National Seismological Network believes an eruption is “probable” in a matter of days, weeks or a few months.

The upgrade in the threat level is due to “important changes in seismic activity of Volcano Turrialba associated with the movement of fluids, gas and magma beneath the surface, different from that observed in past years,” Mora-Amador’s statement says.

Temperatures around some fumaroles on the volcano have risen to as much as 800° Celsius, accompanied by eruptions of ash. High-temperature emissions of volcanic gases including sulfur dioxide have increased, causing incandescence in some of the fumaroles, Mora-Amador said, adding that the internal wall of the active crater is very weak due to hydrothermal changes in the volcano. Mora-Amador indicated this could mean a major eruption could jettison material into the atmosphere.

Turrialba is the only volcano in the country currently with a yellow threat-level indicator. An upgrade to red would mean an eruptions is imminent.

Emergency officials in Costa Rica say they have moved some residents away from a volcano outside the capital after it spewed toxic gas and ash, signs of a potentially imminent eruption.

The Turrialba volcano located about 40 miles (65 kilometers) outside San Jose began a series of eruptions in 2007. Several nearby villages were evacuated and a surrounding national park closed in 2010.

Costa Rica’s National Emergency Commission said its volcano warning level was at green on Wednesday, the lowest of three warning levels, but that it had alerted residents about the possibility of an evacuation and already moved some villagers away from the populated areas closest to the volcano so they would not be harmed by erupting gases.

Katla volcano (Iceland): small earthquake swarm, but not likely indicator of activity in the near future

Tuesday May 29, 2012 12:09 PM | Age: 15 hrs

A swarm of 14 small to very small mostly very shallow quakes occurred at Katla volcano yesterday and today. Epicenter depths were reported between 0.1 and 12.2 km. Judging from the depth and magnitude of the quakes, the most likely cause for the seismic swarm are adjustments of the hydrothermal system under the icecap, and probably not magmatic intrusions (which would be possible indicators of a future new eruption).

Volcano belches ash in Russia's Far East

5/29/12

VLADIVOSTOK - A volcano in Russia's Far East spewed ash high into the sky on Tuesday following a series of tremors, local media reported.

The column of ash from the 3.3-km-high Shiveluch volcano reached up to 7.3 km above sea level, according to the Itar-Tass news agency.

No impact or damage has been reported vis-a-vis the powerful outburst, which came in the wake of a chain of seismic events around the region.

Located on the Kamchatka peninsula, Shiveluch has been active since September 1980.

Preventive alert declared for three Costa Rican volcanoes
May 30, 2012 - By Tico Times
A ‘green alert’ still allows visitors access to the volcanic areas.
The National Emergency Commission (CNE) on Wednesday declared a preventive “green alert” due to recent seismic activity at three volcanoes: Rincón de la Vieja, in the northwestern province of Guanacaste, Poás, northwest of San José in the province of Alajuela, and Turrialba, in the eastern province of Cartago.

“The CNE’s alert is supported by reports from technical and scientific agencies that note the volcanoes are in constant activity,” the commission stated.
Turrialba Volcano, 70 kilometers east of the capital, has seen significant volcanic and seismic activity in recent months, prompting the National Seismological Network to upgraded its own color threat level to yellow.

Emissions of gas at Poás Volcano are expected to increase, and Rincón de la Vieja Volcano has also seen significant volcanic activity, the CNE noted.
Despite the warning, access to the volcanoes will remain open to the public, but visitors must follow guidelines issued at each national park’s entrance.

Colombia - 500 evacuated in volcano alert
5/30/12  A light spewing of ash amid renewed rumblings in the Nevado del Ruiz volcano prompted Colombian authorities to evacuate 500 people from beneath its flanks and briefly suspend flights at four airports.

The volcano's seismic activity was more intense than episodes in April and early May, when it emitted columns of steam, said the government geological agency Ingeominas. The 17,160ft volcano spouted ash that fell on population centres including the western city of Manizales.

Swarm of earthquakes shake around Hawaii volcano
HAWAII VOLCANOES NATIONAL PARK, Hawaii: A large number of earthquakes has been rattling the Volcano area on Hawaii Island over the last few days. The quakes have been small, with no damage reported. Still, a handful of those temblors have been 3.0 magnitude and over.

The USGS Hawaiian Volcano Observatory’s “Recent Earthquakes in Hawaii” page shows a constant swarm of quakes surrounding the Hawaii Volcanoes National Park, home of the active Kilauea Volcano. We took a screen grab of the screen of the USGS HVO earthquake page, and it shows the long list stretching all the way back to Friday, June 1st.

16 earthquakes have already registered on the list before noon on Tuesday, Hawaii time.
On Tuesday, the HVO staff makes mention of the quakes on their Kilauea volcano update page:
Quote:

The GPS network recorded weak extension overall for the past few months with superimposed contraction and extension fluctuations corresponding to DI tilt events. Seismic tremor levels were generally low, decreasing from a peak around 11 am Sunday. A whopping thirty-three earthquakes were strong enough to be located beneath Kilauea volcano: 4 deep earthquakes below the southwest rift zone, 3 beneath the west edge of the summit area, 7 within and below the upper east rift, 1 north of the middle east rift zone, 7 on south flank faults, and 11 mostly shallow long-period (LP) earthquakes within the Koa`e Fault Zone beneath the Kulanaokuaiki Camp Ground; a quick check this morning showed no obvious new cracking on the surface near the campground.


The rise of the Kilauea summit lava lake level in Halemaumau crater continued with several overflows of the inner ledge. At Pu`u `O`o, scientists report lava also rose within the east collapse pit; to the southeast, lava flows continued to advance on the coastal plain.

Stromboli volcano (Italy) activity update: strong and frequent explosions at summit crater

Friday Jun 08, 2012 09:38 AM | Age: 20 hrs

BY: T

Stromboli volcano is in a phase of strong activity. Reports by visitors and images taken with the webcams show that in particular the northwestern vent in the summit crater often produces strong explosions that shower the crater terrace with incandescent lava.

Since the last lateral eruption in March 2007, Stromboli has been in a heightened state of activity overall during most of the past years, indicating that magma levels inside the conduit are relatively high. The question is when again the magma finds its way out through a fissure on the flank on Sciara del Fuoco to produce another effusive eruption with a new lava flow.

Fuego volcano erupts, Guatemalan authorities report

Published June 10, 2012

EFE

The Fuego volcano, located about 50 kilometers (31 miles) south of this capital, on Sunday spewed a column of ash up to a kilometer (about 3,300 feet) high, a government agency reported.

The National Vulcanology Institute said in a communique that the volcano, which rises 3,763 meters (12,230 feet) above sea level, on Sunday erupted effusively, according to seismic recordings and the images received from a camera at the observatory at Panimache.

The volcano's activity presently consists of emissions of red hot lava being hurled from the crater to a height of some 500 meters (1,625 feet), the agency said.

The institute went on to say that three rivers of lava were emerging from the crater and moving down the sides of the mountain.

Volcano Warned Scientists Months Ahead of Deep-Sea Eruption

6/10/12


An underwater volcano gave off clear signals well before its outburst last year that it would erupt, findings that could help forecast such eruptions in the future, researchers say.

Submarine eruptions account for about three-quarters of all of Earth's volcanism. However, the overlying ocean and the sheer vastness of the seafloor make detecting and monitoring them difficult.

Now robot submersibles and a host of other scientific instruments are helping scientists learn more about these mysterious volcanoes. Their findings could lead to short-term forecasting of undersea eruptions in the future.

Hundreds briefly evacuate as volcano erupts in northeast Indonesia
POSTED June 14, 2012 BY BNO News 0 Comments

TERNATE, INDONESIA (BNO NEWS) -- Hundreds of residents in northeastern Indonesia fled their homes on Wednesday after a brief eruption at Mount Gamkonora, spewing towering columns of ash and smoke and prompting officials to raise the volcano's alert level to the second-highest state.

The 1,635-meter (5,364 feet) tall volcano, which is located on the west coast of Halmahera island in the Maluku Islands and is part of North Maluku province, began to erupt on Wednesday afternoon and sent thick ash clouds up to 3,000 meters (9,842 feet) high, although no lava flows were seen.

The Antara news agency reported that hundreds of residents living on the volcano's slope evacuated the area following the eruption, but they returned hours later after officials determined their communities are not currently at risk. New evacuations could be ordered if activity at the volcano continues to increase.

Following Wednesday's eruption, the country's Volcanology and Geology Disaster Mitigation Center (PVMBG) decided to raise the volcano's alert status to Siaga (level 3), the second-highest level. The agency uses a warning system with four levels of alert, with level 1 being the lowest and level 4 being the highest.

Colombia volcano erupts, prompts evacuations
June 30, 2012   BOGOTA (Reuters) - Colombia evacuated people from communities close to the Nevado del Ruiz volcano after an eruption on Saturday that spewed smoke and ash from its crater, bringing back memories of avalanches that in 1985 buried tens of thousands under rocks.
President Juan Manuel Santos said on his Twitter account that the area around the Nevado del Ruiz, in the central spine of Colombia's Andean mountain range, had been put on red alert and people should leave the area.

Even as volcanic activity began to subside, emergency services urged 4,800 residents in Caldas and nearby Tolima province to get to safety, according to Carlos Ivan Marquez, who heads the security effort. The volcano is about 110 miles west of the capital Bogota.
"It's fundamental that communities near to the volcano follow all security recommendations; that means preventative evacuations and that people remain calm," Marquez said.

El Hierro volcano (Canary Islands): continuing earthquakes, volcanic tremor and eruption warning
Jun 26, 2012  While the unusually strong earthquake swarm under El Hierro Island continues, harmonic volcanic tremor has reappeared short time ago at about 16h10 UTC.
The tremor, a low-frequency ground vibration, is thought to be caused by moving magma. It had been strong yesterday and correlated well with a southward propagation of earthquake locations, suggesting that magma at about 20 km depth flew from underneath the El Golfo area towards the EL Julan (south) coast, in a similar way as before the Oct 2011 eruption, but became blocked there, and did not reach the southern rift zone near La Restinga.

After the cease of tremor in the afternoon, earthquakes still continued at high rate, marking a record figure with over 180 quakes larger than M2 yesterday alone, and more than 150 quakes larger than M1.5 so far today.
In other words, pressure continued to cause wide-spread rock fracturing underground and cause small intrusions of fluids. Now, the re-appearance of tremor could mean that magma is moving again somewhere underneath the island. Where to and whether or not it might reach the surface and initiate a new eruption is difficult to know at the moment. It is essential to continue to monitor location and magnitude of earthquakes.

Volcanic activity lifts Canary island
Jun 28, 2012  Following days of almost continual earthquakes, residents of the small Canary island of El Hierro are once again living in fear of a volcanic eruption as their island begins to lift.
http://www.youtube.com/watch?feature=player_embedded&v=_1sx739w704

According to the National Geographic Institute of Spain, increases in seismic activity on the island has seen literally hundreds of earthquakes, known as a swarm, shaking the island and gradually increasing in strength since June 25. Around 750 earthquakes have been recorded although few have been strong enough to be felt by the residents until the last two days
The island has been placed on yellow alert by the security committee in charge of operations as the earthquakes increase. The largest so far was registered at 4.0 on the Richter scale on Wednesday June 27.

More frightening for the approximately 10,000 residents is the fact that a bulge has developed in the island, lifting it five centimetres in four days. Whereas the volcanic activity of 2011 was based out at sea, this time the magma appears to be forming right underneath the island and the pressure is building. Scientists on the island are using the position of the earthquake epicentres to try and work out where the magma from the volcano will come to the surface.The longer it takes to find a vent, the more the pressure from the magma will grow and the larger any possible eruption is likely to be.
Earthquake Report says that PEVOLCA (Civil Protection from Volcanic Risk) has said that there is an acceleration in the flow of magma, with a "clear process of inflation".

4.8 magnitude earthquake near Nabro volcano

July 1, 2012  – We have just received a USGS Notification of a new 4.8 magnitude earthquake in the immediate vicinity of the Nabro volcano. M4.8 is a very strong earthquake for volcanic circumstances. A new eruption cannot be excluded but we will have to wait until satellite images and SO2 satellite pictures are available and this can take a couple of hours. As far as we could see on this afternoon weather and Modis satellite images, NO eruption has taken place. Certainly to be followed closely the following days. EMSC has decreased the initial depth to a new shallow 5 km, but due to the error margins even this new value will not be very accurate but the USGS shows the earthquake erupted at a depth of 10 km (6.2) miles under the ground. We hope to receive the normally very accurate Djibouti data later today. The border area in between Eritrea and Ethiopia is an absolute NO GO zone controlled by the army. A lot of people were killed when the volcano erupted on June 12 2011. The erupted was detected by a M5.1 earthquake.

Rumblings under Tongariro volcano NZ
July  20, 2012

Scientists have raised the Volcano Alert Level at Mt Tongariro after a series of quakes beneath the volcanic complex.
GeoNet said typically Tongariro experienced two such quakes - magnitude 2.5 or less - a year, but there had been more than 20 since July 13.
In a Volcanic Alert Bulletin issued this afternoon, it said the sequence started on July 13 and declined for a period, before restarting on July 18 and increasing in number yesterday.

‘‘These indicate unrest at Tongariro and give reason to change the Volcanic Alert Level to level 1 [from 0] and the aviation colour code to yellow [from green].’’
‘‘These earthquakes are small (magnitudes <2.5 ) and have only been well recorded by a few of the seismometers in our permanent network.
The earthquakes cluster in a zone between Emerald Crater and the Te Mari craters at 2-7km depth.

GeoNet said to better understand the significance of the quakes it was planning to put portable seismic recorders around the epicentres and conduct sampling of selected hot springs, crater lakes and fumaroles in the area.
The Te Mari craters, about  2km east of Ketetahi hot springs on the north side of Mt Tongariro, were the last craters confirmed as active on Tongariro.
In 1869 a large eruption accompanied by an earthquake at Tongariro formed the upper Te Mari Crater during an explosive eruption.
Maori descriptions talked of "bright red flame through the smoke that would burst and fall like snow", GeoNet said.

GNS Science volcanologist Brad Scott said the increased activity just means that something has upset Tongariro,
and some subterranean process is occurring.  It may or may not develop into anything further.

Giant quake a record-setter
July  20, 2012

Even though a magnitude-8.6 undersea earthquake that occurred far west of Sumatra on 11 April 2012 caused no damage and triggered no tsunami, it was still a record-setter.
For one thing, it was the largest quake ever measured far from the boundary of a tectonic plate, researchers report online in Science.
Also, the so-called intraplate quake is the largest ever measured for a fault zone for which the two sides of the fault slide horizontally past each other
rather than having one side of the fault shoved beneath its neighbour.

The epicentre of the quake was located about 400 kilometres southwest of the magnitude-9.1, tsunami-spawning quake that occurred
off the northwestern coast of Sumatra on 26 December 2004.
Over the course of about a minute and a half, this spring's shake ruptured 500km of three separate but related faults, all of which were highly stressed.
A lot of that stress was shifted to the area by the December 2004 quake.

The faults unzipped at a relatively slow but steady 2.5km per second, with much of the slippage along the faults taking place more than 25km below the seafloor -
a depth that helped contribute to the quake's great magnitude.

Tongariro volcano (New Zealand): seismic swarm, a possible precursor to new activity

Monday Jul 23, 2012 12:05 PM | Age: 1 days

BY: T

Tongariro volcano is showing signs of a possible awakening. On 13 July 2012, an increase in small (<M2.5) earthquakes was detected. The quakes were clustered at depths of 2-7 km under the area between Emerald crater and Te Mari crater. More than 20 earthquakes were recorded until 20 July, when the seismic activity peaked and prompted GeoNet to raise the alert level from 0 to 1. Compared to a background average of 2 quakes per year, the swarm is significant and could indicate magma movements. Seismic activity dropped on 21 July with only 1 quake since then, but preliminary measurements show an increase in volcanic gas emission. NZ Scientist started to increase their monitoring at the volcano.

White Island(New Zealand) showing signs of unrest

White Island volcano is showing signs of increased activity, GNS Science says.

The volcano, about 49 kilometres off the coast of Whakatane, is a popular tourist spot, but GNS volcanologist Michael Rosenberg says those visiting it should be cautious even though the alert level for the island had not changed.

"Eruptions can occur at any time with little or no warning. The recent changes in activity suggest that the hydrothermal system has become unstable, and as a result the risk has increased," Rosenberg said.

GNS Science has changed the volcano's code from a "normal, non eruptive state" to "experiencing signs of elevated unrest above known background levels".

The volcano's lake level quickly rose by about three to five metres sometime between Friday and Saturday last week, exposing a "vigorous" flow of gas and steam into the air, Rosenberg said.

It has risen in the past, but took much longer than the 24 hours it took to rise three to five metres on Friday and Saturday, he said.

Naples, Italy Super volcano could kill millions near site of Pompeii
8/6/12  The eruption of Mount Vesuvius near Naples, Italy, in 79 A.D. killed thousands of Pompeii residents and remains one of the most famous volcanic explosions in history. But scientists say a hidden "super volcano" in the same area has the potential to kill millions.
"These areas can give rise to the only eruptions that can have global catastrophic effects comparable to major meteorite impacts," Giuseppe De Natale, head of a project to drill deep under the earth to monitor the molten caldera, told Reuters.

A caldera, or cauldron, is formed by collapsed land after a volcanic eruption. It can be just as dangerous as volcanic domes, sending magma and ash shooting into the air. A caldera is located in Campi Flegrei. The regional park, which is named after the Greek word for burning, is a major tourist attraction, and the surrounding area is home to more than 3 million residents.
"That is why the Campi Flegrei absolutely must be studied and monitored," De Natale said. "I wouldn't say like others, but much more than the others exactly because of the danger given that millions of people live in the volcano."

Volcanic activity world-wide 7 Aug 2012: Tongariro, Etna, Stromboli, Popocatépetl, volcanoes in Guatemala, Colombia, Ecuador
8/7/12  News have been dominated by Tongariro volcano's first eruption in 115 years (New Zealand). At the moment, the volcano is quiet, but eruptions could resume any time.

Etna (Italy): Strombolian activity continues at varying levels. Following a phase of weak activity during 4-6 Aug, an increase of activity was observed at the Bocca Nuova during the night 6-7 Aug.
Also in Italy, the activity at Stromboli (Eolian Islands) has been at relatively high levels over the past days. The number and size of explosions from the summit vents has increased.

Popocatépetl in Mexico: About 1 explosion occurs per hour, and strong glow is visible at night. A relatively powerful eruption late on 6 Aug sent ash to up to 30,000 ft (10 km) altitude.

The volcanoes in Guatemala have shown little changes in activity over the past days.
Fuego volcano has intermittent weak strombolian explosions throwing lava up to 100 m above the crater, and the lava flow on the south flank is still active.
Santiaguito / Santa Maria (Guatemala): Weak to moderate explosions occur regularly and produce ash plumes up to 900 meters high. Avalanches of lava blocks descend on the south flank of the dome.
Lots of seismic activity is visible on the seismograms, most of it related to rockfalls.
Some tremor and shallow volcanic quakes and weak degassing are the only signs of activity reported from Pacaya.

In Colombia, there are currently 1 volcanoes on orange alert (Ruiz)(eruption warning) and 4 on yellow (unrest):
Nevado del Ruiz (Colombia) shows tremor, associated with gas and minor ash emissions at low level. A shallow M1.2 earthquake occurred at 3:11 (local time) near the Arenas crater. INGEOMINAS keeps a close watch of the volcano.
Compared to the previous week, the seismicity at Galeras has increased and shows events related to fluid movements within the volcano. Few weak earthquakes with magnitudes less than 1.1 related to fracturing of rock occurred at shallow depths (less than 4 km) at various locations under the volcano.
Seismicity at Cerro Machin volcano remains at slightly elevated levels with some weak earthquakes SE under the lava dome at depths between 3.5 and 5 km.
At Cumbal volcano, seismicity is still above background levels, but has has decreased. Signals are interpreted as fluid movements under the volcano.
Nevado del Huila The volcano shows normal seismic activity and degassing at low levels with no significant changes to previous weeks. INGEOMINAS keeps the alert level at yellow.

Ecuador:
Tungurahua volcano: Activity remains generally at relatively low levels. Few small to moderate explosions (about 3-5 per day) and weak steam and ash venting continue at Tungurahua. The last reported ash cloud altitude was at 18,000 ft (4.5 km) from an explosion on 6 Aug.
This morning, a more intense phase with volcanic tremor is visible on the seismograms.
Reventador volcano: IG reports a strong steam plume rising 1500 m above the summit, but does no more mention any active lava flow.
Sangay volcano: No recent reports of eruptions from remote Sangay are available, but this might simply incidate that its typical strombolian eruptions are too small.

Planet Earth is riddled with unmonitored volcanoes. Many could erupt with scant notice to the world, causing anything from minor inconveniences to famines or catastrophic death and destruction. Yet when they blow up, these little-known volcanoes don't usually make headlines for two reasons: 1) The people affected by the eruptions are poor, few in number and tend to be ignored by the world at large, and 2) the remote locations of the volcanoes and lack of monitoring equipoment make details of eruptions scarce.

One very unusual example of such a volcano is Ol Doinyo Lengai of Tanzania. The name means "Mountain of God." After spending the previous four decades in relative rest, the mountain erupted violently in late 2007 and continued erupting through early 2008 with the coldest lava on Earth. Still, it's lava and it made life pretty difficult when the ash and rocks rained down on nearby Masai villages like Naiyobi, seen in this image. The villages were evacuated for a while. When people returned they found their water fouled and many grazing lands unusable -- a hard blow for people who depend on their cattle for their living.

In Jan. 2009, U.S. Geological Survey scientists David Sherrod, Thomas Casadevall and Gari Mayberry answered a call from the government of Tanzania for technical assistance in assessing the danger of Ol Doinyo Lengai. The following are some of their images and reflections from the expedition.

NEW ZEALAND No warning before volcanic eruption
8/23/12  Aucklanders may get only a day or two warning of a volcanic eruption and will know just hours before where it will explode, a scientific paper says.
The 1.4 million people living on the Auckland volcanic field make too much noise for existing instruments to hear what is happening below the surface.

"This means that localisation of a future eruption site is only likely to occur within a few hours or days of an eruption," the paper in the Journal of Remote Sensing of Environment says.
Each new vent in Auckland will occur at a new location, rather than an existing volcano, creating uncertainty over where it will hit.

Volcano activity of August 23-24, 2012 – Mt. Tongariro, Sotara, Shiveluch, Karymsky, Santiaguito, Fuego, Sakurajima, Batu Tara, Tungurahua, Kilauea and Nevado del Ruiz

8/24/12

August , 2012 volcano activity

Mount Tongariro volcano (New Zealand) showed some seismicity earlier today (see seismogram below). The activity can only be seen in Oturere and West Tongariro seismograms (close to the Te Maari craters). Below also one of the rara clear view images of Mt. Tongariro with a strongly steaming vent. N report from GNS science about the seismicity however.  The Park service has announced that the trekking trails at Mount Tongariro would be reopened. A 3 km hazard and risk zone will remain in place for some time and might be further reduced once new information of the gas and ash composition is known.

According to INGEOMINAS, the Observatorio Vulcanológico and Sismológico de Popayán reported that during 8-14 August seismic activity at Sotará increased. The seismic network recorded 110 magnitude 0.2-1.6 events mainly located in an area 0.1-5 km NE of the peak, at depths of 2-6 km. Inflation was detected in the NE area, coincident with the zone of increased seismicity. Web-camera views showed no morphological changes. The Alert Level was raised to III (Yellow; “changes in the behavior of volcanic activity”), or the second lowest level. (Smithsonian Institute)

KVERT reported moderate seismic activity from Karymsky during 10-20 August. Satellite imagery showed a weak thermal anomaly on the volcano during 10-13, 15, and 18-20 August. The Aviation Color Code remained at Orange.

KVERT reported that during 10-18 August weak seismic activity was detected at Shiveluch. Observers noted gas-and-steam activity during 15-17 August; weather conditions prevented observations of the volcano on the other days. Satellite imagery showed a thermal anomaly on the lava dome during 10, 12-13, and 18-19 August. Seismic activity increased to moderate levels and hot avalanches were observed during 19-20 August. The Aviation Color Code remained at Orange.

Insivumeh reports 2 moderate explosions at Santiaguito (Santa Maria), Guatemala. The other Guatemala volcano, Fuego sends a white plume approx. 50 meter in the air and grumbles every 1 to 3 minutes. See also seismograms from both volcanoes.

8/25/12  Tangkubanperahu volcano (West Java): increased earthquakes prompt rise of alert level

An increase in seismic activity at Tangkubanperahu volcano near Bandung, the capital of West Java, has been detected since 13 August and promted the Indonesian Volcanological survey (PVMBG) to increase the alert level of the volcano from 1 (normal) to 2 (alert) on 23 August.

Between 1 July and 23 Aug, 264 volcanic earthquakes were recorded, which is almost double to values measured during similar periods of time at the beginning of the year. In addition, pulses of volcanic tremor could be recognized.
Tangkubanperahu has 2 main craters, each about 1000 m wide and 400 m deep, filled by crater lakes, Kawah Ratu (queen) and Kawah Upas, respectively. The craters and lakes along with fumaroles and warm springs are popular tourist destinations. (It is recommended not to climb the volcano's crater, which is a popular tourist destination in the area.
The last eruptions of the Tangkubanperahu were phreatic explosions in 1994.

Chile Reclus volcano increased number of earthquakes as sign of reawakening
Aug 31, 2012  Some unrest is going on at Reclus volcano in southern Chile, located between Aguilera and Monte Burney in Patagonia, the Eruptions Blog writes:
"Over the summer, earthquakes began to be felt in towns in the region of the volcano and a potential for new activity from the Reclus has prompted geologists to visit the volcano later this spring (southern hemisphere). Interestingly, one article mentions that an overflight of the volcano in 2008 spotted cracks on the glaciers that cover the volcano along with traces of ash. However, the direct connection between the seismicity in Patagonia and Reclus is still tenuous, so further observations of the remote volcano will need to be done."
Reclus has had at least 4 historical eruptions around, 1908, 1879, and in 1869. Although these were small, the volcano has produced larger explosive eruptions in the past and should be closely monitored.

Residents, Tourists Warned as Indonesia's Anak Krakatau Activity Increases.
Bandarlampung. Volcanic ash from the increasingly active Anak Krakatau has reached a number of areas in Lampung, prompting officials on Monday to issue a warning for local residents and tourists.
"The ash was carried by wind from the southeast to the south, reaching Bandarlampung," Nurhuda, who heads the observation and information section of the Meteorology, Climatology and Geophysics Agency (BMKG) in Lampung, said according to state news agency Antara.
Nurhuda said the ash fell over several subdistricts in Bandarlampung, about 130 kilometers away from Anak Krakatau.
"It is rather unusual for the dust to be this thick," said Juniardi, a resident of Bandarlampung who complained that the falling dust was also hampering visibility.

Nicaragua volcano belches ash cloud, residents evacuated

9/8/12

MANAGUA (Reuters) – Nicaragua’s tallest volcano belched an ash plume up to 2 1/2 miles (4 km) into the atmosphere on Saturday, prompting the evacuation of hundreds of nearby residents who heard eruptions emanating from its crater.

There were no immediate reports of injuries or damage, authorities said.

The 5,725-foot (1,745-meter) San Cristobal volcano, located about 95 miles (150 km) north of the capital Managua in the country’s volcano-dotted northwest, has been active in recent years, and stirred in mid-2008, when it expelled gas and rumbled with a series of small eruptions.

September 9, 2012  Volcanic activity world-wide 16 September 2012: Popocatepetl, El Hierro, Fuego, Santiaguito, San Cristobal, Santiaguito, Little Sitkin, Manam, Batu Tara, Sakura-jima
A slight increase of activity can be noted at Popocatépetl volcano in Mexico. The frequency of explosions has increased to more than 1 per hour, i.e. doubled when compared to last week.
The more energetic explosions produced small ash plumes rising up to 1 km. Episodes of volcanic tremor occurred as well, CENAPRED writes.

The new seismic swarm at El Hierro continues with hundreds of small quakes per day concentrated at about 20 km depth in the south-central part of the island near El Pinar. Pulses of tremor and a slight inflation are visible as well, but for now, it seems that magma is not moving much.

San Cristobal volcano had a small explosion yesterday at 8:17 am local time. Recent measurements showed an increase of SO2 emissions to 2,490 tons per day, i.e. almost double than before. Also, seismic tremor increased in the evening of 15 Sep.

Fuego volcano, Guatemala: Activity remains at normal levels with sporadic weak to moderate explosions with ash rising 400-800 meters and some rumbling sounds. The lava flow to the Taniluya canyon has apparently decreased a lot, as INSIVUMEH reported it to be only 50 m long yesterday.

Santiaguito volcano continues to have occasional explosions ejecting ash columns to 500 meters height, which spread west and northwest over the region of the villages of El Rosario and San Marcos, Palajunoj. There is constant activity in the 4 active lava flows, generating avalanches of blocks deposited within the river banks Nima Nima I and II.
Most other volcanoes in Central and Southern America have not shown any significantly unusual behavior.

Satellite observations:
Batu Tara had its daily explosion to send ash to about 7,000 ft altitude, VAAC Darwin reports.
A strong SO2 plume was visible from Manam volcano (PNG) today, suggesting that there is heightened activity or an eruption.
Sakurajima volcano seems to be having a break from its relatively strong phase over the past days. There was only one probably weak explosion reported during the past 24 hours.

Volcanic Activity Up in Several Locations
September 18, 2012  Solo, Central Java.  As two volcanos in the eastern part of Indonesia continued to erupt, Mount Merapi in Central Java has been displaying increasing activity, with rumblings in the past week.
“In the evenings, there are rumblings that are accompanied by the ground shaking,” Sapto, from Samiran village in the district of Boyolali on the slope of Merapi.
He said that the 2,968-meter volcano was also active during the day, as evidenced by the thick column of ash billowing out from its crater.

Sapto said that as of Monday, local authorities had not issued any information to the public regarding the volcano.
Subiso, head of Selo subdistrict in Boyolali, confirmed that no official advisories or warnings had been issued yet about the increased activity on Merapi.
However, he said that the rumbling sounds from the volcano were almost routine in the area, and added that the situation there “is still safe.”
Ngatini, another resident said that the rumblings did not disturb local residents too much.
“If an eruption is imminent, the rumbling will be heard continuously and there will be some ash rain,” she said.

Merapi last erupted in October 2010, spewing enormous amounts of ash. Pyroclastic flows, fast-moving currents of superheated gas and rock, killed more than 300 people along the heavily populated slopes and forced 350,000 to evacuate.

Meanwhile, with a small eruption still taking place on Mount Lokon in Tomohon, North Sulawesi, authorities there are maintaining the alert status for the volcano and have banned all human activities within a 2.5-kilometer radius of the crater.
Farid Sukendar, head of the Lokon volcano observation post, said that  the mountain erupted after dusk on Saturday, spewing superheated volcanic material up to 600 meters and ash up to 1,500 meters into the atmosphere.
“This volcano is active and therefore we should remain vigilant because it could erupt any time,” he said.

Arnold Poli, secretary of the town of Tomohon, located at the base of the mountain, said that the authorities were continuously monitoring the volcano. He said that the series of eruptions had not affected the activities of the local population but added the authorities were calling on everyone to remain alert.
He also said that despite the volcanic activity, the government had yet to evacuate anyone from the villages of Kinilow and Kakaskasen III, the two villages closest to the smoldering crater.
“No one has yet been ordered to evacuate,” he said.

Mount Soputan, in North Sulawesi’s South Minahasa district, and Mount Karangetang in the Sitaro Islands district across from the northernmost tip of Sulawesi remained on a government-ordered standby alert status, or just one rung below the most severe alert.

“There are now three volcanoes in North Sulawesi under the standby alert status,” said Hooke Makarawung, head of the North Sulawesi Disaster Mitigation Office (BPBD).
“People should remain vigilant.”
He said that about 110 people had been evacuated from the slopes of Karangetang and that the North Sulawesi administration had sent relief supplies to them.
Djauhari Kansil, the deputy governor of North Sulawesi, said that those evacuated were from East Siau subdistrict, but he added that in the daytime, the people were allowed to return to their village to work their fields.
They have been asked to return to the shelters in the evening.

The volcanology office also announced it had raised the alert level for Mount Gamalama, on Ternate Island in North Maluku province, to standby.
The office, on its website, said that the alert status was raised on Sunday.
The site offered no further details.

The 1,715-meter Gamalama, a conical volcano that dominates Ternate Island, last erupted in December, destroying more than 100 houses and leaving farmers devastated after a thick layer of ash smothered fruit trees and crops.
Four villagers were confirmed dead in that eruption.
Metro TV reported on Monday that the mountain spewed a white column of ash about 500 meters into the atmosphere.

There was also some volcanic debris thrown up by the mountain but on a smaller scale.
It also said the local volcanology authorities had declared a 2.5-kilometer exclusion radius around the crater of the erupting volcano.
On Sunday evening, the smoke and volcanic debris thrown up by Gamalama reached about 1,000 meters into the atmosphere.
Anak Krakatau in the Sunda Strait between Java and Sumatra also showed some signs of activity earlier this month. The volcano is the remnant of Krakatau, the site of an earth-shattering eruption in 1883.

China's Changbaishan volcano showing signs of increased activity

9/20/12

Roughly 1,100 years ago, the Changbaishan volcano that lies along the border between northeastern China and North Korea erupted, sending pyroclastic flows dozens of kilometers and blasting a 5-kilometer (3-mile) wide chunk off of the tip of the stratovolcano.

The eruption, known as the Millennium eruption because of its proximity to the turn of the first millennium, was one of the largest volcanic events in the Common Era. In the subsequent period, there have been three smaller eruptions, the most recent of which took place in 1903. Starting in 1999, spurred by signs of resumed activity, scientists established the Changbaishan Volcano Observatory, a network to track changing gas compositions, seismic activity, and ground deformation. Reporting on the data collected over the past 12 years, Xu et al. find that these volcanic indices each leapt during a period of heightened activity from 2002 to 2006. The authors find that during this brief active period, earthquake occurrences increased dramatically. From 1999 to 2002, and from 2006 to 2011, they registered 7 earthquakes per month using 11 seismometers. From 2002 to 2006, this rate increased to 72 earthquakes per month, peaking in November 2003 with 243 events. Further, tracking the source of the earthquakes, the authors tie the bulk of the events to a region located 5 kilometers (3 miles) beneath the volcanic caldera, a source that slowly crept upward throughout the study period, suggestive of an ongoing magmatic intrusion. Gas composition measurements collected from hot springs near the volcano showed spikes in carbon dioxide, hydrogen, helium, and nitrogen gases, which the authors suggest could be related to magmatic outgassing. Ground deformation studies, too, show a brief period of rapid expansion. The authors suggest that though Changbaishan is likely not gearing up for an imminent eruption, one could be expected in the next couple of decades.

October 17, 2012  HAWAII VOLCANOES NATIONAL PARK, Hawaii: Kilauea Volcano has been putting on quite a show lately… as the lava lake within the Halemaumau Crater has reached its highest level since the summit eruption began in 2008.
The lava lake at Kīlauea’s summit was only about 150 feet below the floor of Halemaʻumaʻu crater on Sunday — the highest it has reached, according to the scientists of the USGS Hawaiian Volcano Observatory.

For the past several months, lava within the summit vent has been slowly rising. As of October 5, 2012, lava reached a level that covered the previous high-lava “bathtub” ring within the vent.
It was around this time that the bangs and booms of the volcano began to be heard as far away as the Jaggar Museum Overlook in Hawai`i Volcanoes National Park, thrilling crowds day and night.

Volcanism in the American Southwest
Released: 10/19/2012 1:30:00 PM

FLAGSTAFF, Ariz. — Experts in volcano hazards and public safety have started a conversation about volcanoes in the southwestern United States, and how best to prepare for future activity. Prior to this meeting, emergency response planning for volcanic unrest in the region had received little attention by federal or state agencies.

Though volcanic eruptions are comparatively rare in the American Southwest, the states of Arizona, Colorado, New Mexico, Nevada, and Utah host geologically-recent volcanic eruption deposits and are vulnerable to future volcanic activity. Compared with other parts of the western U.S., comparatively little research has been focused on this area, and eruption probabilities are poorly understood.

“A volcanic eruption in the American southwest is an example of a low-probability, but high-impact event for which we should be prepared to respond,” said USGS Director Marcia McNutt. “No one wants to be exchanging business cards during an emergency, and thus a small investment in advance planning could pay off in personal relationships and coordination between scientists and first responders.”

"The goal of the conference is to increase awareness of volcanism and vulnerabilities in the American Southwest, and to begin coordination among volcano scientists, land managers, and emergency responders regarding future volcanic activity," said Dr. Jacob Lowenstern, one of the organizers of the conference, and the U.S. Geological Survey Scientist-In-Charge of the Yellowstone Volcano Observatory. "This is the first time these federal, state, and local agencies have met to discuss their roles, responsibilities, and resources, should an eruption occur."

The "Volcanism in the American Southwest" conference on Oct. 18-19 in Flagstaff, Ariz. was organized by the USGS, Northern Arizona University, University at Buffalo, and New Mexico Bureau of Geology and Mineral Resources, the meeting included interdisciplinary talks, posters, and panel discussions, providing an opportunity for volcanologists, land managers, and emergency responders to meet, converse, and begin to plan protocols for any future volcanic activity.

Study: Massive volcanic eruption in the cards for Japan
12/3/12  Japan should brace for a catastrophic volcanic eruption at some point, say experts, citing a massive buildup of magma at many of the nation's 110 active volcanoes.
The last particularly serious eruption in Japan occurred in 1914, when Mount Sakurajima in southern Kagoshima Prefecture blew its top.
According to study by volcanologists, Japan, which lies on the Pacific Rim of Fire, has been shaken by more than 1,000 volcanic eruptions over the past 2,000 years.
"The possibility of a major eruption in the future is real," said Yoichi Nakamura, a professor of volcanology at Utsunomiya University who has been analyzing volcanic eruptions with a team of researchers.

15 Signs That The Ring Of Fire Is Waking Up As We Head Into 2013

While most of the world has been focused on other things, the Ring of Fire has been quietly waking up.  Over the past couple of months, there has been a steady string of noteworthy volcanic eruptions and earthquakes that have occurred along the perimeter of the Pacific Ocean.  But because none of them have happened near a highly populated area, we really haven’t heard much about them in the news.  But if activity along the Ring of Fire continues to increase, it is inevitable that a major event will happen near a major city at some point.  When that happens, the entire world will be focused on the Ring of Fire once again.  Most people don’t realize that approximately 90 percent of all earthquakes and approximately 75 percent of all volcanic eruptions occur along the Ring of Fire.  The entire west coast of the United States sits along the Ring of Fire and a massive network of faults runs underneath California, Oregon and Washington.  Fortunately, the west coast has not experienced any devastating seismic events in recent years, but scientists assure us that will change at some point.  So it is important to sit up and take notice when there are reports of increasing activity along the Ring of Fire.

Unfortunately, most Americans cannot even tell you what the Ring of Fire is.  The following is how Wikipedia defines the “Ring of Fire”…

   The Pacific Ring of Fire (or sometimes just the Ring of Fire) is an area where large numbers of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements.

It runs roughly along the rim of the Pacific Ocean.  Coastal residents of four different continents realize that a major event along the Ring of Fire could fundamentally change their lives in a single moment.

Nearly all of the worst earthquakes in modern history have occurred along the Ring of Fire.  When the Ring of Fire is very active, it is a very big deal.  That is why so many people are alarmed that the Ring of Fire seems to be entering a period of increased activity.

The following are 15 signs that the Ring of Fire is waking up as we head into 2013…

#1 Mount Lokon, which is located in Indonesia, has erupted more than 800 times since July.  On Monday, volcanic ash from the volcano reached heights of up to 10,000 feet.

#2 An “orange alert” had been issued for towns and villages near the Tungurahua volcano in Ecuador.  On Tuesday it erupted and shot lava up to a half mile above its crater.

#3 Lava is still flowing out of the Tolbachik volcano which is located on the Kamchatka Peninsula.  Anyone that has ever played the board game “Risk” knows where Kamchatka is located.

#4 Lava also continues to flow and ash also continues to rise from the Fuego volcano in Guatemala.

#5 On Tuesday, an ash plume more than 2.5 kilometers high had risen from the Paluweh volcano in Indonesia.

#6 There was an average of about 4 seismic events per hour at the Popocatépetl volcano in Mexico on Tuesday.

#7 Scientists recently discovered “one of the world’s weirdest volcanoes” on the floor of the ocean just off the coast of Baja, Mexico.

#8 Mt. Fuji (located not too far from Tokyo, Japan) has been dormant for about 300 years, but in recent months there have been increasing signs of activity there.  One study recently found that a “magma chamber under the mountain has come under immense pressure“, and one prominent scientist is warning that Mt. Fuji is due for “a big-scale explosive eruption“.  Authorities were alarmed when a tunnel leading to Mt. Fuji collapsed on December 2nd, killing 9 people.

#9 Scientists are now warning that there is a very dangerous build up of magma at a large number of Japan’s 110 active volcanoes.

#10 A magnitude-6.1 earthquake struck off the coast of Sulawesi, Indonesia on Monday.

#11 A magnitude-6.0 earthquake hit the New Britain region of Papua New Guinea on Saturday.

#12 A magnitude-6.5 earthquake struck the Gulf of Alaska in mid-November.

#13 A magnitude-7.3 earthquake hit Japan earlier this month.

#14 There has been a substantial increase in earthquake activity in the Long Valley caldera region of California, and authorities tell us that “magma is indeed moving down there“.

#15 Over one recent five week period, more than 170 significant earthquakes were detected in one town in Chile.  That town is now being called “one of the shakiest places on earth”.

All of those events occurred along the Ring of Fire.

So why is all of this happening?

Well, there are certainly a lot of theories out there.

In the United States, a large percentage of the population is convinced that an increase in natural disasters is evidence that we are in the “last days” described in the Bible.  In fact, one recent survey found that a whopping 36 percent of all Americans believe that the increase in natural disasters that we have seen in recent years is an indication that we are in the end times…

   More than a third of Americans believe the severity of recent natural disasters is evidence that we are in the “end times” described in the New Testament — a period of turmoil preceding Jesus’ Second Coming and the end of the world.

   “There is a significant proportion of Americans who see these phenomena through a theological lens,” said Daniel Cox, research director at the Public Religion Research Institute, which released a poll on religion and climate change on Thursday (Dec. 13) in partnership with Religion News Service.

   “It’s hardly a fringe belief. It’s nearly four in 10 Americans who are embracing this,” Cox said.

   The conviction is particularly strong among white evangelical Protestants (65 percent), and less common among Catholics (21 percent) and the religiously unaffiliated (15 percent).

Other Americans believe that there are other causes for all of these natural disasters, and a large number of Americans are absolutely convinced that nothing unusual is happening at all.

Kamchatka and Kuril Island's activity update
Jan 18, 2013  With Kamchatka currently being one of the most volcanically active places on the planet, here is a summary of the current volcanic activity in the past week in the region by the Kamchatkan Volcanic Eruption Response Team.
Lava dome growth and effusion of a viscous lava flow continue at Shiveluch volcano, accompanied by moderate fumarolic activity and incandescence. Satellite imagery showed a thermal anomaly over the volcano all week.

Eruption's at four cinder cones producing fluid lava flows on the S part of the fissure on the flank of Tolbachik continues. A large thermal anomaly on the N part of the fissure was detected on satellite imagery. Gas and ash plumes from Tolbachik rose to heights of 4 KM a.s.l.
A lava flow continues to extrude on the east flank of Kizimen volcano, accompanied by incandescence, hot avalanches and strong gas and steam activity. Two new lava flows were detected on the SE flank of the volcano by satellite data. A thermal anomaly was also observed.

Possible ash eruptions from Karymsky volcano were detected in the past week with ash plumes possible rising to a height of 2.5 KM a.s.l. A thermal anomaly was detected at the volcano on the 11 and 14 January.
Strombolian activity continues at Kliuchevskoi volcano. This was accompanied by gas and steam activity from the summit and incandescence. Thermal anomalies were detected on 11 and 13 Janaury.

Mount Etna roars to life in new eruption -- and it's all on video
2/19/13  Italy's Mount Etna sent lava and gas shooting toward the stars early this Tuesday morning, the first big eruption for the volcano in 2013.
The famous Sicilian volcano burst to life overnight, sending a fountain of fire into the air. The dramatic scene was captured in a video by Klaus Dorschfeldt, a videographer and webmaster at Italy's National Institute of Geophysics and Volcanology.
http://science.nbcnews.com/_news/...uption-and-its-all-on-video?lite=


Mount Etna, one of the world's most active volcanoes, had emitted signs of an imminent paroxysm in recent weeks. On Jan. 22, lava and strong flashes in the volcano's New Southeast Crater were clearly visible from the Sicilian foothills; these often herald a new paroxysm: short, violent eruptive bursts.

Dorschfeldt said he knew Mount Etna's recent signals could precede new activity.  "(I've) followed the activity of Etna for many years, and with time you learn to know it as if it were your friend," he said in an email interview. "Following it constantly (you) learn to be a keen observer and a minor change can lead to something important," he said.
The tallest volcano in Europe, Mount Etna is almost constantly spewing gas or lava. Its Bocca Nuova crater also erupted earlier this year, from Jan. 10 to Jan. 20. In 2011, Etna's violent bursts were spotted from space.

INDONESIA  Alert level raised at Mt Guntur  
4/3/13  Garut Disaster Mitigation Agency (BPBD) chief Zat Zat Munazat has instructed Garut residents, especially those living close to Mount Guntur, to stay calm after the volcano’s alert level was raised to waspada (caution) or level 2 from normal or level 1.

“Mount Guntur is still at a level that poses no danger; so we ask people not to panic,” Zat Zat told The Jakarta Post over the phone on Tuesday evening.
Mount Guntur spewed lava and pyroclastic materials such as hot gas, volcanic ash and rocks, between 1840 and 1847.
“Mount Guntur has not erupted for 162 years,” said Volcanology and Geological Disaster Mitigation Center (PVMBG) head Surono via text messages.

The PVMBG recorded an increase in volcanic activity at Mount Guntur from January to March.
“There has been an increase in seismic activity since 7 a.m. local time on Tuesday in which volcanic tremors have been recorded,” said Surono.

Based on the results of seismic, visual and deformation (the change in shape of the volcano) monitoring, the PVMBG increased the status of Mount Guntur to caution starting at 5 p.m. local time on Tuesday.
“We will continue to intensively monitor volcanic activities while at the same time coordinate with the local disaster mitigation agency,” said Surono. (ebf)

Manila, Philippines — One of the Philippines' most active volcanoes rumbled to life Tuesday, spewing room-sized rocks toward nearly 30 surprised climbers, killing five and injuring others that had to be fetched with rescue helicopters and rope.

The climbers and their Filipino guides had spent the night camping in two groups before setting out at daybreak for the crater of Mayon volcano when the sudden explosion of rocks, ash and plumes of smokes jolted the picturesque mountain, guide Kenneth Jesalva told ABS-CBN TV network by cellphone.

Alert level raised on Philippines Mayon volcano, after volcano exhibits ‘abnormal behavior’
6/1/13
PHILIPPINES – The alert level on Mayon volcano in Albay has been raised to Level 1 after it started exhibiting abnormal behavior, a state agency said today. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) said that in the past 36 hours, three weeks after phreatic explosion on May 7, fumes and crater glow were observed. “PHIVOLCS is raising the alert status of Mayon from Alert Level 0 to Alert Level 1 as a precaution to the public that the volcano is exhibiting abnormal behavior,” it said in a Bulletin issued as of 5:00 p.m. local time on Friday. With this, the agency is warning the public from entering the six-kilometer radius permanent danger zone due to perennial danger of life-threatening rockfalls, avalanches, ash puffs and sudden phreatic or steam-driven eruptions. Mayon’s alert level status may further change if significant changes in monitoring parameters occur, it said. PHIVOLCS also advised residents around the volcano to remain vigilant and to keep abreast of updates on Mayon’s condition through local and national officials. On May 7, Mayon’s phreatic explosion killed seven people, four of them foreigners, who were climbing the cone-like volcano.

San Cristobal volcano (Nicaragua): small ash eruptions on 7 June
6/8/13
New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater.

The new eruptions were followed by a rise in seismic activity in the form of tremor, which rose to about 3 times normal levels during the afternoon. The tremor pulse was still of relatively low energy and in itself not alarming, as the volcano experiences similar phases of elevated seismicity frequently, but given the recent activity, INETER warns that new explosions, possibly larger in scale, could follow with little warning and that air traffic should avoid the area of the volcano.

Unconnected to the new eruptive activity, a small mud flow occurred at 17:10 local time on the lower slopes as a result of heavy rainfall, but did not cause damage.

SINAPRED (Civil Protection) said to be ready to organize the evacuation of some 3,000 people living within a radius of 5 km if necessary, i.e. in case of stronger eruptions.

Philippines - Taal shows signs of restiveness
13 June 2013
RESTIVE Taal Volcano in Batangas province showed heightened activity after at least nine volcanic quakes were recorded around it in the past 24 hours, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
Paulo Reniva, science research assistant of the Phivolcs’ Volcano Monitoring Division, said these quakes were monitored from 7 a.m. Tuesday to 7 a.m. yesterday.
Phivolc recorded seven volcanic quakes in a previous 24-hour observation period.
Despite the increased activity, Reniva said “there is nothing to worry about” since tremors below 10 are still within the “normal parameters” of a volcano under Alert Level 1.
Alert Level 1, which means that hazardous eruption is not imminent, remains in effect over Taal.
However, Reniva reminded the public to stay away from the main crater due to sudden occurrence of steam explosions and accumulation of toxic gases. Taal has about 40 craters, above water and under water, which have so far been discovered.

Volcanic eruptions rage in Alaska
June 28, 2013 – For some reason we can’t explain, activity picked up

ALASKA - Alaska volcano eruptions are entering a more powerful phase. After six weeks of Alaska volcano eruptions reaching five miles into the sky, covering nearby communities with ash and shutting down air flights, there looks to be no end. Alaska volcano eruptions 2013 started in May at the Pavlof Volcano, which is located about 590 miles southwest of the major city Anchorage, in the Alaska Peninsula. The most powerful phase of Alaska volcano eruptions started with low-level rumblings. According to scientists at the federal-state Alaska Volcano Observatory, the latest phase of Alaska volcano eruptions started late on Monday and continued through the night into Tuesday. The blasts emanate from the crater of a 8,261 foot volcano. Tina Neal, an geologist at the observatory said, “For some reason we can’t explain, it picked up in intensity and vigor.’ In May, Alaska volcano eruptions sent a smaller ash cloud 15,000 feet into the air. The ash was visible for miles. Residents were worried that it would damage power generators. The ash plume has so far topped of at an altitude of 28,000 feet, which is too low in the air to affect major air traffic, but high enough that small planes have to fly around it.

Missy Roberts, the vice president of PenAir, which is based in Anchorage, said the airline cancelled one flight and had to re-route other flights. Air traffic controller John Maxwell said, “Everybody is thinking about it. Not that anybody is afraid they’re going to be like Mount Vesuvius and turn into little mummies.” The whole region is under an ash advisory. The National Weather Service warned that people with respiratory ailments in the area could experience breathing problems. They also warned about potential damage to exposed electronic equipment. The Alaska Volcano Observatory reported that King Cove, which is located 30 miles southwest of Pavlof and has a population of about 900 people, has been dusted with ash. The observatory said that a second Alaska Peninsula volcano also continues to experience a low-intensity eruption. The observatory said that ash from Veniaminof Volcano, which is located 485 miles southwest of Anchorage, has been contained to the area around its 8,225-foot summit. The scientists say the eruptions at Pavlof and Veniaminof are unrelated. According to the observatory, there is a third Alaska volcano that is restless is in a more remote area, but that has not started spouting lava or ash. The Cleveland Volcano began its eruptive phase in the middle of 2011 and has been erupting on and off. It has not produced an explosive eruption since May 6. The Cleveland Volcano is located 940 miles southwest of Anchorage. -Kpopstarz

Japan Iwo-Tori-shima Volcano
July 7, 2013
- A possible small eruption occurred this morning. Tokyo VAAC received a (pilot) report of an ash plume rising to 7,000 ft (2.1 km) and drifting 40 nautical miles to the north of the small island. No ash could be detected on satellite images, and sometimes weather clouds are mistaken for ash plumes. On the other hand, the volcano has had relatively frequent small eruptions during the past centuries and new activity would not be a surprising event. The volcano’s last eruption was in 1968. –Volcano Discovery

Volcano covers Japan city in ash
Aug. 19, 2013
A volcano has erupted in south-west Japan and coated a nearby city with a layer of ash.
People in Kagoshima wore raincoats and used umbrellas to shield themselves from the ash after the Sakurajima volcano erupted yesterday afternoon.
Local media said drivers had to turn on their headlights and reported the ash resembled driving through snow at night.

Kyodo News said the plume was 5,000 meters high and lava flowed about a kilometre from the fissure.
It also said that railway operators stopped service in the city while ash was removed from the tracks. It reported that no one has been hurt.
Japan has frequent seismic activity. Kyodo cited the Japan Meteorological Agency as saying there are no signs of a larger eruption at Sakurajima but similar activity may continue.

By morning, the air was clearer as masked residents sprinkled water and swept up the ash. The city was mobilising garbage trucks and water sprinklers to clean up.
But business largely returned to normal in the city of 600,000 people living only 10 kilometres (six miles) from the volcano whose eruptions are part of their daily life.

"The smoke was a bit dramatic, but we are kind of used to it," said a city official. The eruption was the 500th this year of Sakurajima, a statement from the city said.
JMA said there are no signs of a larger eruption but similar activity may continue. It maintains an earlier warning that people should not venture near the volcano itself.

Japan’s Sakurajima volcano rocked by another large explosion- damages cars
9/4/13  A moderately large vulcanian explosion occurred this morning, producing significant fallout of lapilli and small bombs in several kilometers distance. Cars parked at the Arimura Lava observatory observation point to the south of the volcano were damages and windshields broken, at a distance of about 4 km. There are no reports of injuries to people. The ash plume from the eruption rose to approx. 12,000 ft (3.6 km) elevation, i.e. about 2.5 km height. In itself, today’s explosion is not even among the largest that have occurred in the past months, but the volcano clearly continues to be in a state of elevated activity when seen on a long-term average. The following webcam time-lapse video shows frequent ash emission and explosions from the volcano. In a recent interview with Radio New Zealand, volcanologist Masato Iguchi mentions that the volcano might be heading for a larger eruption comparable to that of 1914: “The magma level deep within the volcano is back to about 90% of what it was before the 1914 eruption. So we do have to worry about a big eruption in the long term.” –Volcano Discovery

Jebel Zubair volcano erupts in the Red Sea
10/12/13

As of today, the submarine eruption continues with the production of a steam plume of variable size, not always easily identifiable on satellite images. A SO2 plume is also visible on satellite data drifting from the eruption site. No ash can be seen on satellite imagery, only steam, and the area of discolored water (indicator of suspended particles) is small if not has disappeared. That suggests that the eruption is currently rather weak and probably has not yet entered the so-called surtseyan phase where solid fragments (ash, lava blocks) are ejected above the surface of the sea. –Volcano Discovery

Seismic Swarm Momotombo volcano cause 300 microearthquakes
11/7/13
http://translate.google.com/trans...n-momotombo-causa-300-microsismos

A seismic swarm in the Momotombo volcano last August claimed nearly 300 microearthquakes in a single day, more than twice as common tremors reported the same month, reported the Nicaraguan Institute of Territorial Studies (INET).

According to the Monthly Bulletin of Earthquakes and Volcanoes of INET, the Momotombo swarm of microearthquakes caused 284 on August 17.

The Momotombo, located north of Lake Managua, presented 524 microearthquakes between 16 and 18 August, according to the report.

The microearthquakes are earthquakes with magnitudes less than the magnitude of 1.0 on the Richter scale, which are not perceived by the population.

The swarm in August Momotombo volcano did not cause any damage in Nicaragua.

Regarding the normal seismic activity, the INET recorded 177 tremors with a magnitude of 1.0 Richter or more, both on the Pacific Ocean, and in the volcanic chain and northern Nicaragua.

The tremors under the Pacific Ocean were located off the coast of Corinto, Masachapa and The Small mouth, in the subduction zone, ie at the point of collision of continental plates Cocos and Caribbean, according to the report.

The earthquakes in the volcanic chain were located in San Cristobal volcano, Masaya and Concepcion.

The northern tremors occurred in the provinces of Estelí, Madriz, Nueva Segovia and the North Atlantic Autonomous Region (RAAN).

Most of the earthquakes, ie 54, had magnitudes between 3.0 and 3.9 Richter.  Another 50 earthquakes showed a magnitude of between 2.0 and 2.9 Richter.  The rest had magnitudes between 1.0 and 1.9 Richter, according to the bulletin.

Nicaragua is considered a country with high frequency of earthquakes.  2,000 tremors occur each year on average, according to statistics from INET.

2013 marks record year for the number of volcanoes erupting across the planet

December 5, 2013 – GEOLOGY – This year will go down on record, as seeing the most volcanic eruptions recorded in modern history. The previous number was set in 2010, at 82 volcanic eruptions for the year. The number of volcanoes erupting across the planet has been steadily rising from a meager number of just 55 recorded in 1990. While most scientists may readily dismiss any significance to the latest figures and may be quick to say the planet is just experiencing normal geological activity, it does raise other concerns about just what may be transpiring within the interior of our planet. The average number of volcanic eruptions per year should be about 50 to 60; as of December 5, 2013, we already at 83. Volcanic eruptions are one way the planet dissipates a dangerous build-up of heat, magma, and pressurized gases. The planet’s outer core is thought to flirt with critical temperatures in the range of around 4400 °C (8000 °F). Any rise or major fluctuation in interior gradient could have profound and disruptive effects on processes whose very properties are government by convective heat emanating from the planet’s outer core: magnetic field propagation, tectonic plate movements, sea-floor spreading mechanics, and mantle plume activity. Mantle plumes or hotspots are thought to be the central mechanism which fuels the vast underground chambers of many of the world’s supervolcanoes. –The Extinction Protocol
