Moderate earthquake shakes Southern California

Updated at 3:07 p.m. ET: A moderate earthquake rattled Southern California on Saturday morning, shaking homes across the Inland Empire region and causing buildings to sway in Los Angeles. There were no reports of injuries or serious damage.

The quake, initially reported at magnitude 4.1, was later downgraded to 3.8. It was centered along the San Andreas Fault about two miles northwest of Devore, in San Bernadino County, the U.S. Geological Survey reported. It struck at 8:07 a.m. at a depth of more than six miles.

"I was just sitting in my old chair when the house started shaking," Frank Chavez of Crestline, a mountain town just east of the epicenter, told The Associated Press. "I looked at my wife and we both said, 'earthquake!'. It was no big deal. These get to be old hat if you live in California awhile."

A San Bernardino County Sheriff's dispatcher in nearby Rancho Cucamonga said the station shook for a few seconds, but there were no calls about damage or injuries, the AP reported.

Buildings swayed in downtown Los Angeles, about 60 miles to the west, according to local media reports.

The USGS said it didn't expect any serious damage from the quake.

NBC4’s Facebook page lit up with reactions from people throughout Southern California who said they felt the quake.

Desiree Carroll said she thought a truck went off the 57 Freeway and hit her house in Diamond Bar.

Pat Gowder said he heard the rumble rather than felt it. “Sounded like my house was sliding but didn't feel movement. I live in Glendora,” Gowder wrote.

Michael V. Muñoz wrote, “Oh Ok! So it wasn't just me feeling like I was going to passout after my run this morning!”
