Minor quake on Hayward Fault shakes Bay Area

A magnitude 3.0 earthquake centered near Berkeley jostled the Bay Area on Tuesday afternoon, the third notable quake along the Hayward Fault this year.

The 4:05 p.m. shaker was felt by residents around the Bay but did not cause any significant damage, according to United States Geological Survey seismologist Steve Walter.

The quake was centered near the same spot as a 3.4 earthquake on Feb. 23. The Hayward Fault — which runs along the foothills bordering the east side of the Bay — was also hit with a 4.2 quake near Piedmont on July 23.

“There have been a few events on the Hayward fault in the last few months,” Walter said. “Month-to-month it would look out of the ordinary, but there are patches along the Hayward fault that pop off every once in a while.”

Walter said the frequency of the earthquakes was not unusual, although the July event near Piedmont was in a location where activity had not been felt for several decades.

The USGS tracks earthquakes using sensors around the Bay as well as a “Did you feel it?” feature on its Web site, www.usgs.gov.

While readings from seismometers create a specific map of the time and magnitude of earthquakes, the “Did you feel it?” map allows people to input their location and their own description of the quake, to show where the trembling was felt.
