San Francisco Earthquake Shakes Bay Area About Two Miles East Of Berkeley
San Francisco Earthquake – Bay area residents were startled by repeated tremors at 8:16 p.m. PDT, with a preliminary magnitude of 3.9.
There were repeated jolts that initially came after a 4.0 quake hit in the same region nearly six hours earlier.
Thursday’s quakes come almost 22 years to the day after the Loma Prieta tremor struck the Bay area during the 1989 World Series. The magnitude-6.9 quake killed 63 people, injured almost 3,800 and caused up to $10 billion damage.
San Francisco Earthquake Preparedness Drill
Coincidentally, it all happened as residents in California took part in an annual preparedness drill. One participant joked, stating that it was the best simulator he ever experienced during the test. The 4.0 magnitude jolt struck at 2:31 p.m. and was centered near San Francisco, six miles beneath the University of California, according to U.S. Geological Survey maps.
Jack Boatwright, a seismologist with the USGS, described it as a “sharp little earthquake” that had a “very nice impulsive character.”
Police and officials at UC Berkeley said they had no immediate reports of injuries or damage.
