SAN FRANCISCO >> A 6.5 magnitude earthquake struck off the coast of Northern California today, jolting residents of the coastal town of Ferndale but bringing no immediate reports of damage or injuries. The Pacific Tsunami Warning Center on Oahu said there was no threat of a tsunami.

The quake hit at 6:50 a.m. in the Pacific Ocean about 100 miles west of Ferndale at a depth of about 3 miles, the U.S. Geological Survey said.

Bonnie Brower, owner of the Ferndale Pie Co., says she was grabbing something from the refrigerator in the restaurant’s kitchen when the quake happened. She did not see any damage, but felt a “big jolt.”

“I just felt this very huge jerk and I didn’t know what it was,” she said. Afterward, Brower said, it felt like the ground was rolling, “like you were on a boat.”
