Residents across Southern California received an unexpected jolt this afternoon when a 3.5-magnitude earthquake, according to the U.S. Geological Survey (USGS), struck near Ontario. Initially reported as a 3.1-magnitude shaker, the USGS later revised the strength of the quake, which hit at approximately 12:56 p.m., with the epicenter located a mere 1.24 miles southeast of Ontario, according to CBS News Los Angeles.

The tremors extended far beyond the immediate epicenter, with residents feeling the quake as far east as Highland, south to Camp Pendleton, west into Lakewood, and north up to Azusa. These details were sketched out by the USGS shake map, revealing the expansive reach of the quake's effects. Meanwhile, NBC Los Angeles reported shaking reports in various communities, including Rancho Cucamonga, Fontana, Upland, and Riverside, among others, detailing how the shaking was felt throughout regions east of Los Angeles.

Following the 3.5-magnitude quake, there were a series of smaller aftershocks ranging in magnitude from 1.0 to 1.8, originating in areas around Ontario, Corona, and Home Gardens, as per NBC Los Angeles.

As of this writing, despite the perceptible shaking, no substantial damage or injuries have been reported, as detailed by ABC7.
