At 3:20 a.m. Pacific time on Sunday, an earthquake with a magnitude of 6.0 hit the San Francisco Bay Area.
The USGS reports that it occurred 6.7 miles below the surface, with an epicenter just south of Napa and about 30 miles northeast of San Francisco. This is the strongest earthquake felt by the region in 25 years, since the 1989 Loma Prieta quake, which had a magnitude of 6.9.
There have been no deaths or major injuries reported so far, but there are several damaged buildings and roads in and around Napa, including a damaged highway foundation near the city of Vallejo.

Additionally, at least 42,000 homes are without power in the area. At 5:47 am, a magnitude 3.6 aftershock occurred, and the USGS says the probability of another aftershock is strong, with a 54 percent chance of another strong quake in the area in the next week. It'll probably be weaker than this earthquake, but there's a 5 to 10 percent chance it could be equal in magnitude or stronger.
The earthquake is believed to have occurred along the Franklin Fault, which has been inactive for roughly 1.6 million years and runs parallel to a number of more frequently active faults, including the Rodgers and San Andreas. Over time, as the Pacific Plate slides past the North American Plate, energy builds up along these faults and is occasionally released during earthquake events.
