Multiple Minor Earthquakes Shake Various California Locations Oct. 22-23

Several small earthquakes ranging from magnitude 2.0 to 3.3 were recently detected across various counties in California, including San Bernardino, San Mateo, San Benito, Lake, and Fontana. These tremors, occurring at shallow depths, were generally felt by residents but caused no significant damage, consistent with data that quakes below magnitude 5.4 rarely cause harm. The U.S. Geological Survey encourages those who felt the quakes to report their experiences via the USGS Felt Report form to help with data collection. Earthquake safety experts recommend actions such as dropping, covering, and holding on during a quake, and provide specific guidance for people indoors, outdoors, in cars, or in bed. California remains one of the most earthquake-prone areas in the U.S., with thousands of detectable quakes annually, though only a fraction cause damage. These recent events highlight the importance of earthquake preparedness and awareness for residents in the region.
