BERKELEY -- The second 3.7 magnitude earthquake in just over 48 hours centered near the same location on the Hayward fault as the Wednesday night temblor shook the Bay Area at about 10:49 p.m. Friday evening.
The quake, which struck at about 10:50 p.m., had a preliminary magnitude of 3.7 and was centered about 2 miles east southeast of Berkeley, just across the Bay from San Francisco, according to the U.S. Geological Survey.
There were no intial reports of any damage or injuries.
The temblor occurred on the Hayward Fault, which geologists believe is due for a large quake in the potentially lethal 6.7 to 7.0 range.
The earthquake occurred on the Hayward fault line and although it was a minor quake, it was felt across a broad swath of land.
The Great Quake of 1868 struck on the Hayward Fault, a magnitude 6.9 rumbler that killed five people. Severe quakes have happened on the Hayward Fault every 151 years, give or take 23 years, meaning it is now into the danger zone.
