Ontario, CA — A magnitude 4.0 earthquake in Southern California rattled the Inland Empire early Sunday morning, waking residents and shaking homes across multiple counties.
According to the U.S. Geological Survey (USGS), the earthquake struck at 3:51 a.m., with its epicenter located just south of Highway 60 near the Ontario International Airport at a depth of approximately three miles.
Though the quake was felt widely across Riverside, San Bernardino, Los Angeles, Orange, and even northern San Diego counties, no significant damage or injuries were reported. The earthquake, initially recorded as a 4.3 magnitude before being downgraded, was followed by several minor aftershocks, the strongest registering at 2.5.
Thousands of earthquakes hit California annually, but only about 15 to 20 exceed a magnitude of 4.0, according to the USGS. While Sunday’s quake caused no immediate harm, it’s important to remember that injuries can still occur during seismic events, particularly if individuals are unaware of safety precautions.
The California Office of Emergency Services recommends practicing the “Drop, Cover, and Hold On” technique to protect yourself and reduce injury risks during an earthquake. Staying alert and knowing how to respond can make all the difference in staying safe.
Thankfully, this time, there were no reported injuries, but these incidents serve as reminders of how unpredictable nature can be. Personal safety should always be a priority during such events. We extend our thoughts to those affected by the tremor and hope everyone stays vigilant and prepared for future seismic activity.
