Several magnitude 2 and 3 earthquakes rumbled through the San Francisco Bay Area on Friday. It’s the latest seismic activity to add to a swarm of 60 earthquakes greater than magnitude 1 to hit the Danville area in the past week. The largest in the sequence, a magnitude 3.6 earthquake, came at 12:19 p.m. Friday. The U.S. Geological Survey received reports from more than 1,000 people who said they felt the quake, extending from the East Bay and into San Francisco. The quake was quite shallow, less than a
third of a mile under the surface of the earth. A magnitude 2.8 aftershock was felt two minutes later. San Francisco has been shaken by a series of small earthquakes over 24 hours in California – the US state where a ‘Big One’ could happen at any moment. Friday’s seismic sequence began at 2:32 a.m., with a magnitude 2.7 temblor, followed by a magnitude 2.8 earthquake less than an hour later. A magnitude 3.3 earthquake hit at 5:28 a.m. The BART train service delayed trains after the magnitude 3 earthquakes Friday as a safety precaution. READ MORE
