Magnitude 3.2 earthquake strikes near Concord
A preliminary magnitude 3.2 earthquake shook the Concord area shortly after noon on Friday, according to the United States Geological Survey. The earthquake was centered just over a half mile south of the East Bay city. Light shaking was reported in parts of the Bay Area. There were no immediate reports of damage. While the quake was minor, it occurred in a seismically active region along the Concord-Green Valley Fault system. The right-lateral strike-slip fault system experiences a steady creep of up to 5 mm per year, and has been linked through complex fault interactions to nearby faults, including the Mount Diablo Thrust and the northern Calaveras Fault, according to the USGS. The last major surface-rupturing earthquake on the Concord-Green Valley Fault is estimated to have occurred between 200 and 500 years ago. According to the 2003 Working Group on California Earthquake Probabilities, there is a 4% chance that the fault system could produce a magnitude 6.7 or greater earthquake within the next 30 years.

3.2 magnitude quake detected east of San Diego
(FOX 5/KUSI) — A 3.2 magnitude earthquake was detected in eastern San Diego County on Wednesday morning, according to the United States Geological Survey. The quake was detected at 9:31 a.m., near the community of Borrego Springs, at a depth of approximately 2 miles. Which active fault zones are in San Diego County? In the first hour after the quake, nearly two dozen people had used the USGS 'Did you feel it?' tool, with some of the responses coming from as far away as the San Diego coast, a distance of about 90 miles. No damages were reported as of publishing time. Southern California regularly detects earthquakes in the lower magnitudes, with most of these not generating strong enough shaking to be felt at the surface. A 5.2 magnitude earthquake was detected in mid-April in the same area of the county as Borrego Springs, causing strong shaking throughout the southern part of California and parts of the Mexican state of Baja California.
