A pair of earthquakes rattled San Bernardino, California, on Monday morning.
The first struck at 9:44 a.m. local time with an initial magnitude of 3.5, followed by a second at 9:48 a.m. measuring 3.0, according to the U.S. Geological Survey.
Both quakes originated roughly three miles north-northeast of San Bernardino, with depths exceeding four miles. So far, no damage has been reported.
The 3.5-magnitude tremor was felt across several areas, including San Bernardino, Ontario, Victorville, Hesperia, and Riverside. Reports also came in from residents in Inglewood, Redondo Beach, Palm Springs, Huntington Beach, and parts of north San Diego County.
One user on X shared, “Felt both!” while another commented, “Yup felt that one…another day in California.”
According to the USGS Felt Report, more than 230 people confirmed experiencing the shaking.
Some residents admitted they didn’t even notice the tremors, given California’s history of much stronger quakes.
“Hell, I’m IN San Bernardino – and I needed social media to tell me there was an earthquake,” one person wrote on X.
“No, did not feel it. And I’m in that area,” another commented on Facebook.
Back in January, California experienced four earthquakes within a single day.
These quakes struck along the notorious San Andreas Fault—a major tectonic boundary separating the Pacific and North American plates. Stretching 800 miles along California’s coastline, this fault has long been a source of seismic concern.
Scientists have repeatedly warned that the region is overdue for a catastrophic earthquake—one that could register a magnitude of 8.0 or higher.
While no injuries or structural damage were reported this time, the quake activity followed a devastating series of wildfires that erupted in Southern California on January 7.
Both the northern and southern segments of the San Andreas Fault carry a significant risk of triggering a massive earthquake in the coming decades.
Such an event—often referred to as “The Big One”—could result in around 1,800 deaths, 50,000 injuries, and $200 billion in damages, according to estimates from the Great California Shakeout.
Experts believe the risk is serious. “We are fairly confident that there could be a pretty large earthquake at some point in the next 30 years,” Angie Lux, a project scientist specializing in Earthquake Early Warning at the Berkeley Seismology Lab, told DailyMail.com.
