OFF THE EUREKA COAST (CBS SF) — A strong 6.9 magnitude earthquake struck off the Northern California coast Sunday night, with shaking felt as far away as San Francisco according to one KCBS listener, but so far, there are no reports of damage, and no risk of a tsunami.
The quake was centered 50 miles off the coast from Eureka, along the San Andreas fault, about four miles below the sea floor.READ MORE: Atmospheric River: Parts of San Mateo County Pummeled with Heavy Rain, Flooding
