NAPA, Calif.-- 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.
Napa Fire Department Operations Chief John Callanan says the city has exhausted its own resources extinguishing six 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.
Callanan says three people are reported to be in critical condition, including a young child who was struck by part of a fireplace and airlifted to a specialty hospital for a neurological evaluation.
Inspectors are evaluating damaged buildings, bridges and roads.
The city of Napa in California wine country said in a statement Sunday that two adults and one child have critical injuries and Queen of the Valley hospital in Napa has treated 87 people. Hospital spokesman Vanessa DeGier says most patients have cuts, bumps, bruises.
The earthquake struck just before 3:30 a.m. about 4 miles northwest of American Canyon, which is about 6 miles southwest of Napa.
Napa Division Fire Chief Darren Drake says the quake caused six significant fires, including at a mobile home park. Four mobile homes have been destroyed and two others damaged.
Thousands are without power, buildings and roadways have been damaged, and water and gas breaks have been reported.
The extent of the damage isn't clear but Napa Division Fire Chief John Callanan says two major injuries have been reported, and hospitals have been very busy with moderate injuries.
Napa Fire Capt. Doug Bridewell says the quake has caused fires and collapses. He himself had to climb over fallen furniture in his home to check on his family before reporting to duty. He says it was the worst shaking he'd ever been in.
The shaking emptied cabinets in homes and store shelves, set off car alarms and had residents of neighboring Sonoma County running out of their houses.
The U.S. Geological Survey says the 6.0-magnitude earthquake struck just before 3:30 a.m. Pacific time about 10 miles northwest of American Canyon. That's about 6 miles southwest of Napa, in California wine country.
USGS says it's the largest earthquake to shake the Bay Area since the 6.9 magnitude Loma Prieta quake in 1989.
