The extent of the damage wasn't immediately clear. Two major injuries have been reported, and hospitals have been very busy with moderate injuries, Napa Division Fire Chief John Callanan said.


The 6.0 magnitude earthquake struck just before 3:30 a.m. about 10 miles northwest of American Canyon, which is about 6 miles southwest of Napa, in California wine country, Leslie Gordon of the U.S. Geological Survey said.  It's the largest earthquake to shake the Bay Area since the 6.9 magnitude Loma Prieta quake in 1989, the USGS said.
