Magnitude 3.5 earthquake felt across San Francisco Bay Area

  Magnitude 3.5 earthquake felt across San Francisco Bay Area A small 3.5 earthquake was reported Saturday morning south of San Francisco and was felt over a wide area of the Bay Area. The earthquake's epicenter was one mile from Daly City, two miles from South San Francisco and three miles from San Bruno. The quake struck at 8:41 a.m. Pacific time and occurred at a depth of 4.7 miles.

SAN FRANCISCO – An earthquake with a preliminary magnitude of 4.3 has rattled parts of the San Francisco Bay Area . There are no immediate reports of damage.

Moderate shaking was felt in the Pleasant Hill, Walnut Creek and Concord areas of an intensity that can overturn unsecured objects, such as books and picture frames, and is capable of breaking dishes or windows. Weak shaking was felt in San Francisco, Oakland and San Jose, according to the U.S. Geological Survey. In Fremont, one woman felt short shaking of just 2 seconds.

Close to the epicenter in Walnut Creek, there was strong side-to-side shaking, strong enough to knock CDs off a shelf.

Bay Area earthquakes struck on unusual section of San Andreas fault

  Bay Area earthquakes struck on unusual section of San Andreas fault The magnitude 4.7 earthquake Tuesday east of Monterey Bay hit on a unique section of the San Andreas fault that has long generated interest from scientists. The quake was felt across a wide area and caused no major damage. It was followed Wednesday morning with a 3.4 magnitude aftershock. But it offered a reminder of the San Andreas' presence as a dangerous seismic presence in California.

Residents across the San Francisco Bay area , as far south as San Jose, and as far north as Santa Rosa said they felt shaking. The fact that the Hayward fault produced a magnitude 4 . 5 earthquake means it has, albeit temporarily, reduced strain on that part of the fault without further building up.

"Because any quake can be a foreshock, there's a slight increase in the chance of a bigger quake for the next few days," seismologist Lucy Jones said on Twitter.

The earthquake had a preliminary depth of about 9 miles underneath the surface, fairly deep for this part of the world, Keith Knudsen, USGS geologist and deputy director of the agency's Earthquake Science Center, said in an interview. Such a deep quake would lessen the shaking intensity felt at the surface than if it were shallow.

The earthquake was not directly on top of any of the main Bay Area earthquake faults. The epicenter was about three miles west of the Concord fault, and farther than that off the northern end of the northern Calaveras fault, Knudsen said.

Assistant Chief Chris Bachman of the Contra Costa County Fire Protection District, which provides emergency services to communities close to the quake's epicenter, said that as of about 11 p.m., there were no reports of injuries or property damage related to the earthquake.

California's statewide earthquake alert system launches Thursday

  California's statewide earthquake alert system launches Thursday In Mexico and Japan, warning systems that send out alerts for seismic events have been in place for years, but a similar setup for California has been long-delayed. Finally, on Thursday the first statewide Earthquake Early Warning System will go online. Until now, large-scale alerts have only been available in LA County, where they haven't been triggered yet. As the LA Times reports, Thursday is the 30th anniversary of the Loma Prieta earthquake, where energy from a tremor under the Santa Cruz mountains took up to 35 seconds to reach the northern edge of San Francisco.

A 4 . 5 magnitude earthquake struck early Thursday in Berkeley, California, according to a report from the US Geological Survey, jolting some residents of the densely populated San Francisco Bay area awake in their beds. A 4 . 5 magnitude earthquake that shook the Bay Area on Jan.

The earthquake hit at 2:39 a.m. local time (5:39 a.m. ET), jolting the densely populated San Francisco Bay Area . The epicenter was near the Berkeley-Oakland

The earthquake occurred just three days before the 30th anniversary of the magnitude 6.9 Loma Prieta earthquake, which killed 63 people in Northern California.

In the last 10 days, there have been two earthquakes of magnitude 3.0 or greater centered nearby.

An average of 25 earthquakes with magnitudes between 4.0 and 5.0 occur each year in California and Nevada, according to a recent three-year data sample.

The earthquake occurred at a depth of 9.1 miles. Did you feel this earthquake? Consider reporting what you felt to the USGS.
