Two earthquakes rattle San Ramon region
Two earthquakes struck the San Ramon region Saturday night, just one day after a swarm of six quakes shook the area, authorities said.
The first earthquake, a magnitude 3.9, hit at 6:31 p.m., according to the United States Geological Survey. It was centered three miles southeast of San Ramon and 3.3 miles north of Dublin.
The second earthquake was a magnitude 3.0 that was centered 2.7 miles southeast of San Ramon.
The quakes followed six Friday night that ranged in magnitude from 2.5 to 4.0. Those temblors did not have any immediate reports of injuries but did cause BART trains to temporarily reduce their speed.
There have been several other earthquakes in the region in recent weeks. San Ramon saw 3.1 and 3.0 magnitude quakes on Tuesday.
On Dec. 8, there were more than 30 earthquakes in San Ramon in just a few hour span.
