News: Earthquakes - 3.0 - swarm - Dublin

DUBLIN, CA -- No damage or injuries have been reported but if you live in the San Francisco East Bay your house may have been shaking the last few days. Nearly two dozen earthquakes have hit the Dublin, Ca area since Thursday afternoon. Three more small shakers were recorded early Friday morning. And the biggest so far is documented below. USGS geologists say that with a cluster of quakes like this - the Bay Area could continue to feel the quakes for the next several days or even weeks.
These quakes are not on the dangerous Hayward fault; they are on the so called step-over fault that is between Calaveras and Concord, and all centered near Dublin.
The largest was 3.0 recorded at 6:30 pm on Thursday night.

This comes as a new report warns that the Bay Area is not ready for the big one coming on the Hayward fault.
