Emergency declared after 6.0 earthquake sends 89 to hospital in Napa
A long, rolling 6.0 earthquake shook a wide swath of the Bay Area awake early Sunday, prompting Gov. Jerry Brown to declare a state of emergency. The temblor damaged buildings, cut off power to tens of thousands, sparked fires, and sent at least 89 people to a hospital, including three who were in critical condition.
Centered about nine miles south of wine country's Napa at 3:20 a.m., the quake was felt as far south as Santa Cruz and into Sonoma County. It was the largest earthquake to strike the Bay Area since the 6.9 Loma Prieta temblor of 1989, the U.S. Geological Survey said.
A little more than two hours after the quake, a shallow magnitude 3.6 tremor was reported by the USGS. The aftershock occurred at 5:47 a.m. at a depth of five miles. The National California Seismic System put the chance of a strong aftershock in the next week at 54%. Scientists at UC Berkely released a video showing an early-warning system that sent an alert 10 seconds before the earthquake.
