(ETH) – Another earthquake swarm of four small quakes has reportedly rattled areas around a reservoir in Northern California on Tuesday, for the second time in three days in the same region. According to The USGS, the tremors all transpired along the northern edge of the Calaveras Reservoir in Alameda County, located about 6 miles northeast of Milpitas.
According to the report, a 2.7 magnitude quake struck at 8:16 a.m. local time, followed by a 3.0 temblor about 10 minutes later and then a 1.3. magnitude earthquake in the same area. Then two minutes after 9 a.m., a third 3.3-magnitude earthquake struck the northern reservoir area.
These quakes were all centered along the Calaveras fault system, which is located in the hills east of the San Francisco Bay Area. The quakes were also widely felt by residents in the Fremont, Milpitas, and San Jose areas. “I was just sitting on them bricks right there and I just felt a little jolt,” Milpitas resident Jeff Gio told KPIX-TV after feeling the strongest jolt after 9 a.m.
There have been no reports of damage or injuries from any of the earthquakes. The reported swarm on Tuesday has been the second in three days for the Milpitas areas as Sunday, there was a report of twin quakes also striking along the Calaveras Reservoir.
In less than 30 days ago, two similar-sized shallow temblors also struck the reservoir, the East Bay Times reported. Of course, local residents brushed off the recent activity as just another day living in the Golden State. This region is located along the volatile “Ring of Fire” which is a seismic fault system located at the Pacific Ocean.
