Three light earthquakes shook the San Francisco Bay Area, bringing to 12 the number of temblors to strike the region in 36 hours. No damage or injuries were reported, authorities said. The strongest of the three quakes had a magnitude of 3.3, officials at the UC Berkeley seismographic station said. The epicenter was 20 miles west of Berkeley in the Pacific Ocean. It was followed by another shaker that measured 2.0 and then another at 0.9. U.S. Geological Survey seismologists in Menlo Park said that 11 of the quakes occurred on or near the San Andreas Fault in the Pacific, eight miles from the Golden Gate Bridge. The scientists said that, although the north coast segment of the San Andreas Fault is not continuously active, clusters of small quakes such as those of the last 36 hours are not unusual. All the San Andreas Fault quakes were felt in San Francisco and the area north of the Golden Gate Bridge in Marin County, the seismologists said.
