NAPA, Calif. – A strong earthquake rattled a swath of Northern California's wine country in the early hours of Sunday morning, unleashing most of its damage on the city of Napa in the heart of the vineyard-studded region.
No deaths were reported, but more than 200 people sought medical attention and Gov. Jerry Brown declared a state of emergency for southern Napa County.
Here's a look at the quake and its fallout:
MAGNITUDE: The magnitude-6.0 earthquake was the strongest to hit the San Francisco Bay Area since the 6.9-magnitude Loma Prieta temblor in 1989, the U.S. Geological Survey said. That quake collapsed roadways and killed more than 60 people.
EPICENTER: About 5 miles south of Napa.
INJURIES: Queen of the Valley Hospital in Napa reported Monday that 208 people sought treatment for cuts, broken bones, bruises and other ailments immediately after the quake until 11 p.m. PDT Sunday. Hospital officials could not say how many of them were there for injuries suffered in the quake and how many for more routine injuries and illnesses.
Seventeen patients were admitted, a dozen of them for broken bones and other medical problems directly related to the earthquake. The hospital didn't release details on the other five admitted patients.
In addition, a 13-year-old Napa boy was flown to the children's hospital at the University of California, Davis, Medical Center for a neurological evaluation. His condition was listed as serious, hospital spokeswoman Phyllis Brown said.
STRUCTURAL DAMAGE: Four mobile homes in Napa were destroyed and two others damaged in fires caused by the earthquake.
Mark Ghilarducci, director of California's Office of Emergency Service said at a press conference Sunday that as many 100 homes in the region have been deemed unsafe to enter. The office didn't return a phone call Monday seeking an update.
Rick Tooker, Napa's community development director, confirmed that 49 homes and buildings in the city have been deemed unsafe to enter. In nearby Vallejo, seven commercial buildings are uninhabitable.
Many other structures sustained more moderate damage, including broken windows, toppled furniture and broken liquor bottles and kegs. The quake broke thousands of bottles of wine and toppled barrels.
Pacific Gas and Electric says it has restored power to nearly all the 75,000 customers who lost electricity after the earthquake.
Napa officials report 90 water main breaks. The nearby city of Vallejo reported a dozen main breaks.
The public school district in Napa canceled classes Monday.
