A 3.5-magnitude earthquake struck near Fontana in Southern California on Tuesday afternoon, according to the U.S. Geological Survey (USGS).
The quake hit at 4:54 p.m. about 3.8 miles from Rialto and 4.5 miles from Fontana, at a shallow depth of 3.6 miles. Shaking was felt across the Inland Empire, including Rancho Cucamonga, Riverside, and San Bernardino.
The USGS says weak tremors were also reported as far north as Victorville and as far south as San Clemente. So far, there are no reports of injuries or significant damage.
This latest quake is part of a series of recent small earthquakes in the region. Just last week, a 4.3-magnitude quake shook the Inland Empire, and earlier this summer, seismologists recorded several similar tremors in what experts call the “Fontana trend” — a zone known for clusters of small to moderate quakes.
Seismologists stress that while Tuesday’s quake is considered minor, it’s a reminder that Southern California remains earthquake country. Residents are encouraged to review emergency plans and ensure they have earthquake kits on hand.
