A 4.0 earthquake shook the Bay Area on Monday morning.
The U.S. Geological Survey reported the earthquake at 6:49 a.m. on the Hayward Fault. It was centered in Oakland just south of the merger of Highways 24 and 13.
Damage was apparently limited to a few falling household items, but Bay Area Rapid Transit said it stopped its trains for 10 minutes as a precaution.
The Associated Press reported that the shallow quake was felt in downtown San Francisco, along the Peninsula and in the East Bay as a sharp jolt, followed by a couple of gentle rolls.
