Sunday earthquake largest since Loma Prieta in 1989

Officials: Expect small aftershocks during the next week

A 6.0 earthquake that centered near South Napa shook Bay Area residents in their beds early Sunday morning. U.S. Geological Survey officials said the earthquake is the largest to hit the Bay Area since the Loma Prieta Earthquake almost 25 years ago.

The temblor was recorded at 3:20 a.m. and was located 6 kilometers northwest of American Canyon, according to the U.S. G. S. It had a depth of 10.8 kilometers. The nearest large city to the epicenter is Vallejo. (View a U.S.G.S. shakemap of the earthquake.)

The U.S.G.S. also reported 2.5 and 3.6 magnitude aftershocks about four miles southwest of Napa at 5:01 a.m. and 5:47 a.m., respectively. Several smaller aftershocks have also been reported.

Officials said 30 to 70 small aftershocks could hit the area during the next week.

Emergency agencies are reporting minor injuries but no deaths have been reported. PG&E is reporting tens of thousands of customers are currently without power across the Bay Area, mainly in Napa and Sonoma counties.

A city spokesman for Napa said firefighters are responding to structure fires, and a number of masonry buildings in downtown Napa have suffered severe damage. He said several stores have broken windows and there are water main breaks in several locations.

Napa also opened an Emergency Operations Center in response, and Vallejo activated its center. Vallejo police are reporting isolated structure damage to downtown buildings and on Mare Island. Police are also reporting water outages from water main breaks, minor roadway damage, minor gas leaks and power outages.

While some roads were closed due to possible damage, including the westbound off-ramp of state Highway 37 and westbound Interstate Highway 80 to state Highway 37, they have since been reopened.

There has been no reported damage to roadways in the South Bay, Peninsula and East Bay, according to the CHP.

Law enforcement and emergency agencies across the Bay Area are asking residents not to call 911 unless they have an emergency.

California Gov. Edmund Brown Jr. said in a statement Sunday morning the impact of the earthquake is being felt throughout the region.

"My Office of Emergency Services has been on full activation since early this morning and is working close with state and local emergency managers, first responders and transportation officials to respond to impacts to residents and critical infrastructure," he said. "These safety officials are doing all they can to help residents and those living in affected areas should follow their guidance and instruction."

Yes...this was a real wake up reminder to be prepared.

In Alamo as I am sure in Danville the earthquake was a slow and gentle roll. Nothing like what the Napa region experienced. I hear people in Danville and yes even in Alamo telling others that it was so bad that it almost pushed them out of bed...what an imagination.

And I would like to remind Gov. Jerry Brown that the Office of Emergency Services does NOT belong to him. He should have said, "the office of emergency services etc. etc." NOT MY OFFICE OF EMERGENCY SERVICES. The OOES belong the the tax payers of California...NOT Jerry Brown.

Thanks for listening, Julia Pardini from Alamo
