Sacramento, CA – Seismic activity ticked upward across Central and Southern California on Wednesday, as at least six small earthquakes were recorded within hours, including three near Markleeville and others near Pinnacles, Toms Place, and Desert Hot Springs. The strongest, a 3.2 magnitude quake, struck just northwest of Pinnacles National Park around 2:46 a.m. PDT at a depth of 7.1 km.
According to the U.S. Geological Survey and the California Integrated Seismic Network, the cluster began early Wednesday morning with a pair of shallow tremors southeast of Markleeville, followed by a 2.7 magnitude quake near Toms Place in Mono County. Roughly three hours later, a 2.6 magnitude quake hit near Desert Hot Springs in Riverside County, felt by at least six residents.
While none of the events caused structural damage or injuries, their proximity to populated and seismically sensitive areas has prompted local emergency officials to remind residents to check emergency kits, secure loose items, and review earthquake safety plans.
No official warnings or alerts have been issued, but geologists note these low-magnitude events are typical for the region and could be part of normal tectonic activity or foreshocks.
USGS continues to monitor the area for further movement. Residents near the San Andreas Fault and Owens Valley should stay informed in case of additional activity through midweek.
