A strong earthquake of magnitude 6.5 today struck off the coast of northern California, the United States Geological Survey said.
No major tsunami threat was expected, seismologists said.
The epicenter of the quake, which hit at 6:49 am (1449 GMT), was located 157 kilometers west of Ferndale, California at a depth of 10 kilometers, the US Geological Survey said.
No damage or injuries were reported.
The Pacific Tsunami Warning Center issued a statement saying there is no tsunami threat from the earthquake.
Bonnie Brower, owner of the Ferndale Pie Company, says she was grabbing something from the fridge in the restaurant's kitchen when the quake happened. She didn't see any damage, but said says felt a "big jolt."
"I just felt this very huge jerk and I didn't know what it was," she said. Afterward, it felt like the ground was rolling, "like you were on a boat."
