SAN FRANCISCO, Rabi'I 9, 1438, Dec 8, 2016, SPA -- A 6.5 magnitude earthquake struck off the coast of Northern California on Thursday, jolting residents of the coastal town of Ferndale but bringing no immediate reports of damage or injuries, AP reported. The quake hit at 6:50 a.m. in the Pacific Ocean about 100 miles west of Ferndale, the U.S. Geological Survey said. The Pacific Tsunami Warning Center said in a statement there was no threat of a tsunami. 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 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, she said it felt like the ground was rolling, "like you were on a boat." Dennis Gorton, who owns the Francis Creek Inn in Ferndale, said there was no damage and none of the guests panicked. -- SPA 19:54 LOCAL TIME 16:54 GMT www.spa.gov.sa/w286461
