Earthquakes / volcanoes are common in ALASKA and its islands, so I am just making a thread for ALL of them.
This month there is quite a swarm of quakes.  WATCH.

June 13, 2012  This link was posted 10 minutes after I posted this.  Laughing
An intense earthquake swarm continues to shake the peninsula of Alaska. A 4.8 was also reported in neighboring Kamchatka. The depth of the earthquakes striking Alaska range from 200 km to about 40 km (24.9 miles) and most are occurring about 429 km from the city of Anchorage. Alaska is without a doubt the most tectonically-active region in the United States. Alaska experiences more than half of all earthquakes recorded in North America each year. This is mainly due to Alaska’s unique location, which fits like a piece of a jigsaw puzzle on the northern rim of the Pacific Basin. At the northwest corner of the North America, Alaska is situated at the receiving end of the Pacific Plate as it slides laterally past southeast Alaska and collides directly with the North American Plate across south-central Alaska and along the length of Aleutian Island Chain. The accumulation of tectonic stresses at depth along the plate boundaries and the translation of those stresses into the shallower crust of southern Alaska are believed to be the driving forces behind the high level of earthquake activity that occurs in our state. We’re also seeing seismic stress rippling up the coast of the U.S. from Baja to Alaska. We may be heading for another seismic stress release.

Alaska earthquake wakes Anchorage residents
May 16, 2012
An earthquake strong enough to feel in Anchorage, Alaska's largest city, and surrounding areas of upper Cook Inlet occurred at 7:03 am.
Epicenter was 10 miles southwest of Anchorage's center, at a depth of 35 miles, and the magnitude measured 4.8 on the Richter scale.
The Alaska Earthquake Information Center at University of Alaska Fairbanks lists the magnitude at 4.61 and epicenter 8 miles south of Anchorage at a depth of 37 miles.

5.6 magnitude earthquake strikes off coast of Alaskan peninsula
March 10, 2012 – ALASKA – A 5.6 magnitude earthquake was reported just off the coastline of the Alaskan peninsula at 5:10 am. The earthquake registered at a depth of 17.7 km or 11.0 miles below the surface and struck the ocean floor. The epicenter of the earthquake was 819 km (508 miles) SW of Anchorage, Alaska and 1455 km (904 miles) W of JUNEAU, Alaska. Both seismicity and volcanic activity has been steadily increasing along the Alaskan region over the last several weeks. People in high-risk areas should stay alert for the potential occurrence of seismic episodes. –The Extinction Protocol

Laughing   Major quake rocks Alaska, natives unmoved    Laughing
03 Sep 2011  USGS later lowered the magnitude to 6.8
A major earthquake measuring a preliminary magnitude of 7.1 has rocked remote portions of Alaska.

Alaska Native News notes that the area is frequented by earthquakes every day, although a majority of them have a magnitude less than this.
The website, which describes itself as "news for the people of the last frontier," says there have been numerous quakes in the region in the past week,
with most of the big ones centered off Kodiak Island, far out to sea.

Updated at 10:51 a.m. ET: It's worth noting that a 6.4 magnitude earthquake later rocked northern Argentina, but the epicenter was almost 370 miles underground. Agence France-Presse reports that there were no immediate reports of casualties or damage.

A quake measuring 7.0 hit the same sparsely populated region in January. The epicenter of that quake was also very deep and the effect at the surface was limited.

Updated at 10:26 a.m. ET: Paul Whitmore, director of the West Coast and Alaska Tsunami Warning Center in Palmer, Alaska, says the community closest to the Alaska earthquake is Atka, a village of about 60 people about 100 miles west of the epicenter. The quake was centered about 1,000 miles from Anchorage.

Updated at 10:06 a.m. ET: An aftershock measuring 4.5 hit the area about a half hour after the initial quake, the U.S. Geological Survey says. The initial quake was about 22.1 miles deep, USGS says. Earlier reports had it much closer to the surface.

Updated at 9:25 a.m. ET: The Aleutian Islands are no stranger to earthquakes. Agence France-Presse reports that the islands sit on the Pacific Ring of Fire, a "horseshoe-shaped seismic belt 25,000 miles long where most of the world's earthquakes and volcanic eruptions occur."

Updated at 9:00 a.m ET: The USGS has lowered the magnitude of the quake to 6.8.
Updated at 8:50 a.m. ET: The tsunami warning was canceled after only a small wave was recorded near Atka,

ALASKA  *  Earth's Mantle in Overdrive
May 19, 2010   The mantle under Alaska is moving 20 to 30 times faster than the crust -- reversing the usual order of plate tectonics.
A new 3-D model of the mega-quake and tsunami-launching subduction zone in Alaska has uncovered a big surprise:
The Earth's mantle there is moving a whopping 20 to 30 times faster than the crust.
So instead of being dragged along for the ride as a slab of crust is pushed under another,
the solid rock mantle rock is swirling around the plunging slab like water around a paddle dipped in a stream.

What the models predict are flows up to 90 centimeters per year around the descending slab of crust, said geologist Magali Billen of the University of California at Davis.
Billen co-authored a report on the new model with former graduate student and lead author Margarete Jadamec in this week's issue of the journal Nature.
"On plate tectonics timescales that's screaming fast," said Billen.

More typical plate speeds range from one to 10 centimeters per year.
The model, developed by Jadamec, includes 100 million data points and takes 48 hours to run on a supercomputer with 400 processors.

It incorporates the latest in genuine evidence from the Alaska subduction zone.
This includes something called seismic anisotropy, which exploits special seismic properties of the mineral olivine in the mantle to detect directions rocks are flowing in the mantle.

Because the mantle rocks are under great pressure, they flow like Silly Putty while remaining solid.

Other seismic pieces of the subduction computational puzzle include the shape of the slab that's now being pushed into the mantle and the viscosity of the mantle, explained Billen.
Put the flow direction, viscosity and shape of the slab together with a lot of computer power and you can start to work out the details of what's going on.

"As long as we can put (into the computational model) the right driving force, that's how fast the flow is," Billen explained.
The model also allows researchers to turn up the speed and see how the subduction process might proceed.

"It takes millions of years for the slab (of subducted plate) to descend," said geophysicist Geoff Abers of the Lamont-Doherty Earth Observatory of Columbia University.
"These kinds of models allow the slabs to flap around, which is something you could not do and cannot see."

The swirling of the mantle around the sinking slab could have implications for the super powerful megathrust quakes and tsunamis that the subduction zone is capable of generating, said Billen.
Instead of all the force of the colliding plates being bound up in their collision and vented by large quakes, some energy is being transferred into stirring up the mantle.
"This is a good thing," said Billen.

The model could also help to figure out if a chunk of crust is about to fall off into the mantle and stop the subduction dead in its tracks.
This, in turn, could help to explain why subduction zones start and then stop in different places said Billen.

6.0 earthquake hits Alaska's Aleutian Islands
June 19, 2012
 An earthquake with a preliminary magnitude of 6.0 has occurred in a remote region of Alaska.
The Alaska Tsunami Warning Center says the temblor was centered about 90 miles northwest of Attu Island in the Aleutian Islands. It occurred shortly before 8 a.m. Tuesday.
The center says no tsunami is expected.

Long-grumbling Alaska volcano has explosive ash burst
6/20/12
 A remote Aleutian volcano that has been restless for the past year rumbled to life on Tuesday, shooting a thin cloud of ash several miles into the sky, which could pose a slight hazard to aircraft, Alaska scientists said.
Cleveland Volcano, a 5,676-foot (1,730 meter) peak on an uninhabited island 940 miles southwest of Anchorage, had an explosive eruption at about 2:05 p.m. local time, the Alaska Volcano Observatory reported.

A pilot flying in the area estimated that the ash cloud rose to 35,000 feet above sea level, reported the observatory, which is a joint federal-state organization that monitors Alaska's numerous active volcanoes.
However, satellite imagery shows only a weak ash signal, suggesting a thin cloud that dissipated quickly, said Stephanie Prejean, a U.S. Geological Survey seismologist at the observatory in Anchorage

6.9 magnitude earthquake strikes Aleutian Island regions of Alaska
http://theextinctionprotocol.word...leutian-island-regions-of-alaska/

September 27, 2012 – ALASKA – A strong 6.9 magnitude earthquake struck the Aleutian Island regions of Alaska. The epicenter of the earthquake was 131 km (82 miles) from Adak, Alaska and about 2054 km (1277 miles) from Anchorage, AK. The 6.9 magnitude earthquake registered at a depth of 40 km (25.2 miles) below the earth’s surface. The earthquake struck 33 km south of the Tanaga volcano in Alaska. Tanaga is a 5,924-foot (1,806 m) stratovolcano in the Aleutian Range of the U.S. state of Alaska. There have been three known eruptions at the volcano since 1763. The most recent eruption occurred in 1914 and produced lava flows.

6.4 earthquake Gulf of Alaska
November 12, 2012  
- 34 miles depth
A deep 6.4 magnitude earthquake struck the Gulf of Alaska at a depth of about 55 km (34.3 miles). The epicenter of the earthquake was about 562 km (349 miles) SE from Anchorage, AK.  Today’s earthquake is the latest in a series of powerful quakes that has seen the planet reeling from increased seismicity activity, from Guatemala to Myanmar. Clearly, a season of planetary geological change is upon us. -TEP

Magnitude 5.8 quake rattles Anchorage, Alaska
03 Dec 2012
- A magnitude 5.8 earthquake struck off the coast of Alaska on Monday, close to the city of Anchorage, rattling buildings and knocking bric-a-brac from shelves, but no serious damage or injuries were reported.
The tremor, initially reported as a magnitude 5.7, struck at 4:42 p.m. (8:42 p.m. EST) 25 miles west of Anchorage, the U.S. Geological Survey said.

The quake, relatively shallow at a depth of 33.1 miles, was widely felt in Anchorage, according to Guy Urban, a geophysicist for the West Coast and Alaska Tsunami Warning Center in Palmer, Alaska.
"Some people in Anchorage said some things fell off the shelves," he told Reuters, adding that the center was unaware of any severe property damage or anyone being hurt.

7.7 Quake Strikes Off Alaska – Stan forecast the 7.5 Alaskan shaker in yesterday's quake map posted at 10:30 a.m. The quake hit at midnight local time last night. Normally he has a larger window than 12 hours especially for that large an event. He had been picking up signals in and around the area for several days, and accurately pegged it yesterday morning. The note posted on our annual quake stats page is already proving true that due to the overall drop or 'average' activity for 2012, pressures may be building for significant earthquakes in 2013. Looks like we're starting off 2013 with a bang.

Dome grows in Alaska's Cleveland Volcano
Feb 7, 2013
 Alaska's Cleveland Volcano is heating up and scientists are on alert in case it sends up an ash cloud that could threaten trans-Pacific flights.
The Alaska Volcano Observatory detected elevated surface temperatures Jan. 24 at Cleveland's summit. Satellite data obtained last week indicated that a growing lava dome on the floor of the summit crater had reached about 328 feet, or 100 meters, in diameter.
The summit crater itself is nearly 10 times that size, said Chris Waythomas of the U.S. Geological Survey.
"It does this from time to time and it's a fairly small lava dome," he said Wednesday. "It's not gigantic."
