MISSOULA, Mont. -

Gov. Jerry Brown has declared a state of emergency for the part of California's wine country hard-hit by a large earthquake.
    
The governor issued a proclamation directing state agencies to help respond to the 6.0-magnitude quake that struck early Sunday about 6 miles from the city of Napa.
    
The strongest earthquake to hit the San Francisco Bay Area in 25 years has damaged some of Napa Valley's famed wineries and injured dozens of people, at least three critically. It left cracks in roads, broke water mains, caused more than 100 gas leaks and ignited at least six fires. Fire officials say a fire at a mobile home park destroyed four homes and damaged two others.
    
Napa Fire Department Operations Chief John Callanan says the city has exhausted its own resources extinguishing fires, transporting injured residents, searching homes for anyone who might be trapped and answering calls about gas leaks, water main breaks and downed power lines.
