Swarm of small quakes rattles San Ramon area

San Ramon has had more than 20 small earthquakes in the past 20 hours, which is quite the coincidence because Thursday is the Great California Shakeout, a day to bring attention to earthquake preparedness.

SAN RAMON, Calif. (KGO) -- Another earthquake has struck the San Ramon area. The latest hit at 6:10 a.m. and was centered just east of El Capitan Drive, north of Crow Canyon, the same area as most of yesterday's quakes.

So far there are no reports of damage or injuries, but people are saying they felt it in Danville, Dublin, Pleasanton and Lafayette.

A 2.5 magnitude earthquake also hit five miles north of Vacaville at 6:21 a.m.

A swarm of more than 20 earthquakes shook the area yesterday. The strongest measured a 3.2 magnitude.

Scientists say over the past 20 years, they've seen many small swarms in the area, they don't believe it's a precursor to the big one.
