Small Earthquake Jolts Northern California

A short sharp earthquake rattled California’s San Francisco Bay Area, but there are no reports of injuries.

The U.S. Geological Survey said the 4.0 magnitude quake struck Monday and was centered just north of Piedmont, near Berkeley. It was felt in downtown San Francisco, along the Peninsula and in the East Bay. The quake struck on the Hayward Fault at a depth of about 3.4 miles, according to the USGS.

The shallow quake at 6:49 a.m. was a sharp jolt, followed by a couple of gentle rolls. It was not immediately known if the quake caused damage.

Bay Area Rapid Transit was holding trains on Monday to check the tracks on the public transit system.
