The 6.0 M near the Bay Area this morning was the largest quake to hit that area since the Loma Prieta earthquake almost 25 years ago.— USGS (@USGS) August 24, 2014
UPDATE: Via the San Francisco Chronicle:
There was widespread damage in downtown Napa, with bricks, concrete chunks and broken glass littering the street and debris landing on parked cars. The Old County Courthouse was among the buildings that sustained damage. Emergency workers usually stationed there were moved to the sheriff’s office. There was a report of some buckling on an off-ramp from westbound Highway 37 to Highway 29 at Sonoma Boulevard. As a result, Highway 37 between Fairgrounds Drive and Highway 29 was closed as Caltrans crews assessed the damage. Some buildings in downtown Vallejo also sustained damage. Some power lines were down in western Contra Costa County, but Bay Area bridges appeared to be fine, according to the California Highway Patrol. There were widespread reports of power outages, gas leaks and flooding in the North Bay, with at least 15,000 Pacific Gas and Electric Co. customers without power in Vallejo, Napa, Rohnert Park, Santa Rosa and Sonoma. Police reminded motorists to stop at darkened intersections. Scientists said the quake was 6.7 miles deep and may have hit on the West Napa Fault. It was the largest in the Bay Area since the 6.9-magnitude Loma Prieta quake killed 62 people on Oct. 17, 1989.
