3.5-magnitude earthquake hits near Fontana, USGS says

RIALTO, Calif. (KABC) -- A 3.5-magnitude earthquake struck near the Fontana area and rattled other parts of the Inland Empire Tuesday afternoon, according to the U.S. Geological Survey.

The quake hit at approximately 4:54 p.m. and had a depth of 3.6 miles, USGS said. The agency said the quake struck about 3.8 miles from Rialto and 4.5 miles from Fontana.

So far, there have been no immediate reports of significant damage or injuries. A USGS map indicates weak shaking was felt as far north as Victorville and south in San Clemente.

The quake comes after a 4.3-magnitude earthquake rattled the Inland Empire last week, with shaking felt across Southern California.
