A 6.1-magnitude earthquake rocked California Sunday morning, striking just north of San Francisco, producing power outages and fires throughout the Bay Area and injuring at least 70 people, the Los Angeles Times reported.

CNN reported that the quake, the strongest to hit the Bay Area since 1989, was felt by roughly one million people.

According to the U.S. Geological Survey, the quake's epicenter was 4 miles northwest of American Canyon, close to Napa, and the earthquake hit around 3:20 a.m. PDT (6:20 a.m. EDT).

From the Associated Press:

The tremor set off car alarms and had residents of neighboring Sonoma County running out of their houses in the middle of night. Power was knocked out in some areas.

The USGS says the depth of the earthquake was just less than seven miles, and numerous small aftershocks have occurred in the Napa wine country.

A member of Napa County dispatch tells The Associated Press that there has been one report of structural damage, but additional details were not available.

There was no immediate report of injuries.
