The largest earthquake to hit the Bay Area since 1989 shook Northern California just after 3 a.m. Sunday morning.
The U.S. Geological Survey reported the quake, with a preliminary magnitude of 6.0, was centered about four miles northwest of American Canyon and hit at 3:20 a.m. The temblor, which took place at a depth of about 6.7 miles, was felt at least as far away as Santa Cruz County, according to users of Twitter.
More than 60,000 people were without power in Napa and Sonoma counties, including 27,600 in the city of Napa and 15,400 in the city of Sonoma, according to PG&E.
