UNION CITY — A short, sharp earthquake registering 3.3 magnitude shook underneath multiple East Bay towns but did not cause any injuries or visible damage, the U.S. Geological Survey said Wednesday.
The quake struck at 6:22 p.m., at a fairly shallow depth of just over 3 miles, and was centered under the southwestern edge of Dry Creek Pioneer Regional Park.
According to a USGS “did you feel it?” community intensity map, citizens reported feeling the quake across parts of San Francisco, the Peninsula and the East Bay.

There were no reports of injuries, damage or other disruptions in either quake. BART trains systemwide were briefly delayed for 20 minutes as part of regular quake-based precautions.
USGS scientists have predicted a 63 percent chance of a magnitude 6.7 or larger quake striking the Bay Area in the next 30 years, and recent earthquakes in the East Bay over last weekend and earlier today, as well as in several Northern California towns Tuesday have focused new attention on the threat to the state’s residents, and how best to prepare.
