6.5 earthquake shakes northern CALIFORNIA
January 9, 2010
Powerful quake off the coast of Northern California causes widespread power outages, property damage and minor injuries, fraying nerves in several communities.
6.5 earthquake 33 miles WSW from Eureka, California, many aftershocks.
Many residents lost power, some injuries and damage.
There have been many earthquakes offshore Eureka in the past year or so.
The earthquake struck off the coast of Northern California Saturday afternoon,
shaking buildings south of the Oregon border and knocking out power in several coastal communities.
It had a big jolt to it at the end
At least 12 aftershocks reported
The seismically active California-Mexico border was rattled Tuesday by a magnitude-4.5 aftershock of the major earthquake that hit the region April 4. No damage was immediately reported.
The U.S. Geological Survey said the quake struck at 5:38 p.m. and was centered 18 miles west-southwest of El Centro, the Imperial County seat in California's southeastern corner.
USGS computers initially calculated the quake's magnitude at 5.1, but seismologists downgraded it a couple of hours later after reviewing data from hundreds of seismic stations across Southern California.
"With more stations reporting, you get a more accurate magnitude," said California Institute of Technology seismologist Anthony Guarino.
The aftershock was centered about 40 miles northwest of the magnitude-7.2 quake that struck Easter Sunday in northern Baja California, Mexico, said Susan Potter, a geophysicist at the USGS' National Earthquake Information Center in Golden, Colo.
"The 7.2 quake was shallow and large so we'd expect to see aftershocks for quite some time," she said.
In Mexicali, residents were frightened because memories were still fresh from the earlier quake, said Alfredo Escobedo, Baja California's state civil defense secretary. But no reports of injuries or damages were received, he said.
Inspection teams were sent to small communities on the outskirts of the city to check for damage.
Tuesday's quake was felt at San Diego's Petco Park, about 90 miles to the west of the epicenter.
At the Styles and Smiles salon in El Centro, shampoo bottles rattled but the haircuts and massage therapy sessions continued.
"We just try to keep the customers relaxed," owner Lourdes "Lulu" Castro said. "We're used to it. We were just like, 'OK, here it comes.'"
A magnitude-4.4 earthquake rattled residents of southern California early Tuesday morning, according to the U.S. Geological Survey.
There were no immediate reports of damage or injuries, authorities said. However, police and fire officials said they had received calls from residents awakened by the quake. Its epicenter was 11 miles east-southeast of the Los Angeles Civic Center, the USGS reported. It struck at 4:04 a.m.
"First it was a small one and then a big one," said Chris Curiel, who was working at the Vallejo Mini Market in Whittier, a town near the epicenter. "It felt like the floor was sinking."
He said merchandise on the shelves began shaking, but there was no damage. Because his market is a gas station, earthquakes are a bit more worrisome, he said.
Curiel said he knew immediately an earthquake was happening, and he has felt one before.
Ravi Singh, night shift supervisor at a 7-Eleven in Pico Rivera -- the town a mile east-northeast of the epicenter -- told CNN he was making coffee when the store's windows started rattling. There was no damage, he said. "Everything is fine."
iReporter says "it sounded like there were kids dancing upstairs"
Although the temblor was centered 11 miles below the Earth's surface, according to USGS, the movement was enough to awaken some southern Californians.
"It felt like two quick jolts," said CNN's Rosalina Nieves. "I felt some shaking, and I wasn't sure if it was just my upstairs neighbor ... but then you definitely felt two quick jolts." She said the movement lasted for a couple of seconds.
While earthquakes are common in southern California, Nieves, a native of Los Angeles, said recent earthquakes in Chile and Haiti have caused concern.
"The first thing that jumps into your mind is, 'Is this the big one?'" she said.

Thanks. I heard about this. The Pacific is really shaking, all around the ring of fire.
A Full Halo CME is due to arrive on March 17, 2010.
Incoming CME (Coronal Mass Ejection) from Sun to Hit Earth March 17, 2010
Watch for geomagnetic storms that can knock out satellites, power grids, and cause auroras and sudden extreme weather events and quakes.
A halo CME starting most probably from NOAA AR 11054 (there is an EIT data gap that prevents more definitive conclusions) have been seen on LASCO-C2 at 01:31 UT, it is a fast one according to CACTUS (1656 km/s).
It is expected to arrive to the Earth on March 17-18.

Incoming: SOHO observes a halo CME heading our way.
halo CME A class of coronal mass ejection (CME) that appears as an expanding halo of gas around the Sun in coronagraph images such as obtained by the Solar and Heliospheric Observatory (SOHO). A halo CME occurs when the emitted gas is directed along the line of sight towards the observer. Because they are moving towards us, halo CMEs are more likely to produce effects at the Earth than other CMEs.

INCOMING: This morning, the Solar and Heliospheric Observatory recorded a halo CME emerging from the vicinity of sunspot 1054: movie. The cloud appears to be heading toward Earth and it could spark geomagnetic storms when it arrives on or about March 17th. High-latitude sky watchers should be alert for auroras.
