An earthquake with an estimated magnitude of 6.5 occurred about 25 miles southwest of Eureka, Calif., at 4:27 p.m.

Preliminary reports indicate the earthquake, along the Russ fault, was felt as far away as San Francisco.

[Updated: 5 p.m.: Sandra Hall, owner of Antiques and Goodies in Eureka, said the quake moved her shop in all directions.

Her store is now littered with broken lamps, dishes, and wardrobe items. She said there were at least four people in her store when the quake struck. A couple managed to run out of the store’s main entrance, while two women took cover under a table.

“We’ve been through a lot of earthquakes but I can’t recall there ever being any this bad,” Hall said.]

[Updated, 5:06 p.m.: A tsunami is not expected, according to the National Weather Service. Power is out in at least one neighborhood in the Eureka area, a resident said. Two aftershocks have been detected, magnitude 3.8 and 3.7.]
