USGS: 6.5-Magnitude Quake Reported Off N. California Coast

WASHINGTON (Reuters) -

An earthquake with a magnitude of 6.5 was reported off the coast of northern California on Thursday, the U.S. Geological Survey said.

The quake was centered in the Pacific Ocean about 102 miles west of Ferndale, California, at a depth of 6.2 miles, according to the USGS.

There was no tsunami warning, advisory or threat in effect following the earthquake, the Pacific Tsunami Warning Center of the National Weather Service said on its website.

The quake was first reported with a 6.9 magnitude but then downgraded to 6.5.

In Ferndale, which has a population of about 1,300 people, Mayor Don Hindley said in a phone interview that he had not heard of any damage from the quake. He said he felt the temblor for about 15 seconds.

“It wasn’t that bad at all,” Hindley said.

In the San Francisco Bay area, about 250 miles south of Ferndale, the Bay Area Rapid Transit agency said it was running its system with a 10-minute delay and with trains traveling at reduced speeds due to the quake. The move was a standard precaution by BART.
