An earthquake with a 6.0 magnitude hit northern California’s San Francisco Bay area Sunday morning, according to the U.S. Geological Survey.
The USGS says the depth of the earthquake was just less than 7 miles, and numerous small aftershocks have occurred in the Napa wine country.
California Gov. Jerry Brown declared a state of emergency after the quake.
It was the strongest earthquake to hit the Bay Area since 1989, when a quake struck during the World Series. The USGS says it’s the largest trembler to shake the Bay Area the Loma Prieta quake, with a magnitude of 6.9, which reportedly led to 63 deaths.
The South Napa Earthquake struck about 3:20 a.m. local time, according to the U.S. Geological Survey. The epicenter was located about six miles south-southwest of Napa, California, and 51 miles west-southwest of the state capital, Sacramento.

Thousands of small earthquakes occur in California each year, providing scientists with clear indications of places where faults cut the Earth’s crust. There was 4,895 earthquakes in California between 1974 and 2003 with a magnitude of 3.5 or greater (about 163 a year).
