No tsunami threat after magnitude-6.5 quake off California coast

A magnitude-6.5 earthquake struck 100 miles off Northern California's coastline early Thursday, but there was no threat of a tsunami.

The quake struck at 6:50 a.m. local time at a relatively shallow depth of 7.5 miles about 100 miles west of Ferndale, Calif., the U.S. Geological Survey reported.

Light shaking was felt as far south as San Francisco. No damage or injuries were reported.

The Pacific Tsunami Warning Center issued a bulletin stating the temblor was not sufficient enough to generate a tsunami.

Bonnie Brower, owner of the Ferndale Pie Company, told the Associated Press 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 to the AP. Afterward, it felt like the ground was rolling, "like you were on a boat."

Two nearby aftershocks, measuring 5.2 and 4.9, were also reported, the U.S. Geological Survey said.
