Aftershocks Shake Southern California Following 4.4-Magnitude Earthquake

After a 4.4-magnitude earthquake shook the Devore area Tuesday, more than 30 aftershocks struck across SoCal, according to the U.S. Geological Survey.

More than 6,000 people across SoCal reported feeling the quake at 5:48 p.m., centered about 60 miles east of Los Angeles. Several aftershocks hit the same area, ranging in magnitude from 2.7 to 3.8.

A magnitude-2.7 quake was reported in the area early Wednesday morning.

Shortly after the initial earthquake was reported, Caltrans workers inspected the conditions of infrastructures and bridges in the San Bernardino area.

Hundreds of residents said they felt the aftershocks. Residents from Redondo Beach, Newport Beach, Glendale, and Fontana reported shaking.

"In Devore right now..... Felt like a sonic boom," Treasure Ortiz said on NBCLA's Facebook page.

Louann Hess Koscielski, a Facebook user living in Rialto, said she thought her "window was going to break."

"In the last 10 years, we've had nine quakes above a magnitude of 4, so it's a relatively active area," Lucy Jones, U.S.G.S. seismologist, said.

Jones also said the initial quake was shallow, at just three miles below the surface.
