Earthquake felt as far as Tahoe
The chance of a strong aftershock over the next week from a 6-magnitude earthquake that struck Marin County 3:20 a.m. is 45 percent according the U.S. Geological Survey.
The earthquake was centered eight miles northwest of Vallejo, and damaged buildings in Napa.
California’s Office of Emergency Services was activated, Gov. Jerry Brown said.
“My Office of Emergency Services has been on full activation since early this morning and is working closely with state and local emergency managers, first responders and transportation officials to respond to impacts to residents and critical infrastructure. These public safety officials are doing all they can to help residents and those living in affected areas should follow their guidance and instruction.”
Residents in Reno, Sparks, South Lake Tahoe and Tahoe City reported feeling the earthquake.
According to the Geological Survey, the earthquake occurred near the north shore of San Pablo Bay.
“The bayshore areas in the San Francisco Bay region are underlain by landfill and bay mud and have experienced disproportionately greater damage during historic earthquakes,” geologists said. “Such damage is caused by soil failure in the fills and amplification of ground shaking by the soft bay mud.”
