People as far away as San Francisco reported feeling the quake, but there were no immediate reports of damage. Officials did not issue a tsunami warning.

“It started rolling and I could feel it. I had time to jump out of bed and crouch down and call the dog before it stopped. So it was a long rolling one,” Pam Cahill told the San Francisco Chronicle from just north of Eureka.

The USGS first reported the earthquake at 6:50 a.m. local time.

Ferndale is about 120 miles south of the Oregon border.

Two quakes with magnitudes topping 4.0 shook the region earlier this week -- one on Monday and one on Tuesday.

On Wednesday, a magnitude-6.5 earthquake in Indonesia killed more than 100 people.
