NAPA, Calif. (AP) — The largest earthquake to hit the San Francisco Bay Area in 25 years sent scores of people to hospitals, ignited fires, damaged multiple historic buildings and knocked out power to tens of thousands in California's wine country on Sunday.

The 6.0-magnitude earthquake that struck at 3:20 a.m. about 6 miles from the city of Napa ruptured water mains and gas lines, left two adults and a child critically injured, upended bottles and casks at some of Napa Valley's famed wineries and sent residents running out of their homes in the darkness.
