Moderate earthquake shakes Southern California

Updated at 3:07 p.m. ET: A moderate earthquake rattled Southern California on Saturday morning, 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.

Buildings swayed in downtown Los Angeles, about 60 miles to the west, The Associated Press reported.

Some homeowners in Rancho Cucamonga, just west of the epicenter, reported slight damage, according to City News Service.

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 then 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!”
