Gov. Jerry Brown of California declared a state of emergency for southern Napa on Sunday after a strong earthquake with a preliminary magnitude of 6.0 hit the region, causing scores of injuries and extensive damage and knocking out power to thousands of people across the region. KTLA News
The temblor struck about 10 miles northwest of American Canyon — six miles south of Napa — around 3:20 a.m., according to the United States Geological Survey. It was the most powerful earthquake to hit the Bay Area since the Loma Prieta earthquake of 1989, which collapsed the Bay Bridge. At least four aftershocks were reported Sunday.
