4.2-Magnitude Earthquake Strikes Near Fontana

Residents in the area said they felt a strong jolt.

A 4.2-magnitue quake was strong enough to rattle nerves across four counties, but turned out to be harmless. Melissa Etezadi reports for the NBC4 News at 6 p.m. on Saturday, July 25, 2015.

Residents were jolted out of bed Saturday morning when a 4.2-magnitude earthquake struck near Fontana at 5:54 a.m.

The United States Geological Survey initially reported 4.3-magnitude shake and later downgraded it to a 4.2-magnitude.

Residents in the area said they felt a strong jolt and reported items falling off shelves.

"We felt it very strong. We thought it was an explosion," said Patty Madrid.

The quake struck one mile east, southeast of Fontana, four miles west of Rialto and eight miles east, southeast of Rancho Cucamonga.

More than 3,700 people in Southern California reported feeling the quake on the USGS' "Did You Feel It?" section.

Residents 100 miles south reported feeling the quake in San Diego County. 

Cal Tech Seismologist Jennifer Andrews said the rattler was about 3 miles deep and shallow, "which can be widely felt."  She described the movement as a "strike-slip," meaning the plates moved traversely making the quake feel like a jolt.

Many people quickly took to social media and shared their experiences with the trembler.

"Being a magnitude 4.2 and very shallow, they felt some reasonable shaking," Andrews said.

She added there was a 5 percent chance of a larger earthquake to follow, but the likelihood decreased with time.

Madrid said the earthquake was a very quick jolt and she heard a "loud boom" before going downstairs.
