Borrego Springs, Calif. – A magnitude 3.3 earthquake struck 11 kilometers south-southwest of Borrego Springs Wednesday morning, briefly rattling parts of San Diego County just after 9:30 a.m. local time.
According to the U.S. Geological Survey, the quake hit at 9:31 a.m. PT at a shallow depth of 6.4 kilometers. The epicenter was located in the inland desert region near the Anza-Borrego Desert State Park, roughly 80 miles northeast of San Diego. There were no immediate reports of injuries or damage.
Residents in Borrego Springs and nearby towns such as Ocotillo Wells and Julian reported light shaking, but the tremor was not widely felt in the more populated coastal areas. The California Integrated Seismic Network classified the quake as minor, noting its relatively low magnitude and limited felt reports.
Although no infrastructure impacts were recorded, experts remind residents that even small quakes can serve as reminders to review emergency kits, secure heavy furniture, and know local evacuation routes.
Tuesday’s event follows a quiet seismic period in the region, but officials say continued minor activity is not unusual along Southern California’s complex fault systems.
Seismologists say no further alerts are in effect, but aftershocks are possible. Residents can report shaking at earthquake.usgs.gov.
