A 3.0-magnitude earthquake shook the East Bay region of California early Monday morning, marking the third seismic event in the area within a few days. The U.S. Geological Survey reported the quake occurred at 6:47 a.m.
The epicenter was located east of Mount Diablo, approximately nine miles south of Antioch and 7.4 miles west-southwest of Brentwood. The preliminary measurement indicated the temblor originated about 10 miles below the surface.
This latest tremor follows a 3.4-magnitude earthquake on Saturday and a 2.6-magnitude quake on Sunday. The recent seismic activity has been clustered near the Greenville Fault.
As of Monday morning, there were no immediate reports of damage or injuries resulting from the earthquake.
