Multiple Earthquakes This Morning in Bay Area

A series of small earthquakes have hit the Bay Area in the last hour. I felt only one, the largest one, as a short jolt. The activity is in the area surrounding Concord, CA, which is aprox. 60 miles north west of San Francisco.

UPDATE VIA NBC San Francisco:

In addition to the swarm of quakes today, on Sunday, three earthquakes struck within the span of 15 minutes, according to the USGS. The quakes had magnitudes of 2,5, 3.6 and 2.7.

The Concord quakes Sunday occurred on the Concord-Green Valley fault, one of several in the area that seismologists say are capable of producing major earthquakes. The last large earthquake on the fault happened anywhere from 200 to 500 years ago, the USGS said.
