6.5 quake strikes off California coast

Posted 25m ago

FERNDALE, Calif (AP) — The U.S. Geological Survey says a 6.5 magnitude earthquake has struck off the coast of Northern California.

The USGS says the quake hit at about 4:27 p.m. Saturday about 27 miles from Eureka, a coastal city of about 26,000 that's 110 miles south of the Oregon border.

The National Oceanic and Atmospheric Administration says there is no threat of the quake generating a tsunami.

USGS geophysicist Richard Buckmaster says the quake was felt as far south as Capitola in central California, and as far north as Tiller in central Oregon.

The San Francisco Bay area was struck by two light earthquakes on Thursday and Friday.

6.5 earthquake near Eureka, Calif., snaps power lines and topples televisions [Updated]

January 9, 2010 | 5:50 pm

A strong earthquake, estimated magnitude 6.5, rocked the Eureka, Calif., area this afternoon, snapping power lines, toppling televisions, disrupting power throughout the region and forcing the evacuation of at least one mall.

The earthquake was centered under the Pacific Ocean, about 25 miles southwest of Eureka, at 4:27 p.m. A tsunami was not expected, according to the National Weather Service.

[Updated 5:57 p.m.: The California Highway Patrol in Eureka reported no major damage to roads and bridges and highways and said roads are open.

"Right now it's very preliminary but there does not seem to be any damage that is overly significant." said Capt. Dale Cannon. "We've got some minor glass breakage, some gas mains affected and some power lines down."

He said he has not heard of reports of any injuries.]

“It was a monstrous one,â€

"Five aftershocks followed in the 90 minutes after the quake, the biggest registering at a magnitude of 3.8."

Yeah, but is the Pacific starting to fill in the San Andreas Fault?

There is a small chance — 5 to 10 percent — of another magnitude-6.5 temblor or larger hitting the area over the next week, but the odds dramatically decrease as time passes, the USGS said.

There's also a 78 percent chance of a strong and potentially damaging aftershock magnitude-5 or larger over the same period. The earthquake probabilities are based on statistical observations of past earthquakes in California and are not predictions, the USGS said.

6.5 is actually a pretty strong earthquake.

I get eMail updates from the USGS and there have been amost daily 3.8 range quakes all over the state since Christmas.

California is one of the world's most seismically active regions. More than 300 faults crisscross the state, which sits atop two of Earth's major tectonic plates, the Pacific and North American plates. About 10,000 quakes each year rattle Southern California alone, although most of them are too small to be felt
