SAN RAMON – (INT) – A swarm of minor earthquakes is rattling the San Francisco Bay area.

It began Sunday morning with an M3.8 centered 2-miles southeast of San Ramon. It’s been followed by dozens of minor aftershocks, many too weak to be felt.

Multiple faults run through the area, including the Pleasanton Fault and the Calaveras Fault.

There has been no reported damage.

The US Geological survey recorded at least 37 quakes in the first 8-hours since the initial event.
