Did You Feel That Earthquake? Find Out Where In The Bay Area It Came From

SAN RAMON, CA— A magnitude 3.0 earthquake struck San Ramon yet again, according to the United States Geological Survey.

The temblor was reported just after 8:14 a.m. Friday and was centered about 5 miles underground.

The reported quake on Friday contributes to a series of earthquakes that have recently occurred in or near San Ramon, including the one on New Year's Day a 3.2 magnitude tremor that lightly shook the area at 4:58 p.m.

Additional quakes were recorded on Christmas Eve, Dec. 23, and Dec. 20, following another period of multiple tremors within 24 hours.

These earthquakes are part of an ongoing swarm during a notably active period of seismic activity in the region. Over the last month alone, San Ramon has experienced more than 150 earthquakes—the second-highest total in nearly 50 years. That total increases toover 300 earthquakes since November, according to the USGS.

San Ramon is situated along the Calaveras Fault, which has several smaller faults branching off it. The movement of fluids like water or gas through networks of tiny cracks in these micro-faults can rapidly trigger dozens of small earthquakes.
