A 6.4-magnitude earthquake rocked parts of northern California on Tuesday morning, the US Geological Survey said, waking residents abruptly and knocking out power for thousands.
There are no immediate reports of injuries. The tremor occurred at 2:34 a.m. local time near Ferndale, a small community about 345 kilometers north of San Francisco near the Pacific coast.
The epicenter was just off the coast, at a depth of about 16 kilometers.
Just over 72,000 people remained without power by mid-morning on Tuesday, according to poweroutage.us.
A resident has uploaded images of overturned furniture and smashed dishes in her home.
Police have closed a major bridge in the Ferndale area. Images show that the roadway was considerably damaged. There are also reports of some gas leaks.
A magnitude 3.6 earthquake struck the San Francisco Bay Area early Saturday morning, causing only minor damage. The epicenter of this earthquake was in El Cerrito, about 25 kilometers from downtown San Francisco.
