11:20 AM PT -- The earthquake has now been downgraded to a 6.4 earthquake. It's the strongest quake in the L.A. area since the devastating 6.7 quake that struck Northridge in 1994. That earthquake, however, was centered in the San Fernando Valley ... causing billions in damages. This latest quake was centered in the desert and far away from a major city.
The Fourth of July got off to a terrifying start for folks in Southern California after a preliminary magnitude 6.6 earthquake shook for what seemed like an eternity.
The U.S. Geological Survey says the quake was centered in the Mojave Desert but people all over SoCal -- from Beverly Hills and Marina del Rey to Universal Studios, downtown L.A. and beyond -- felt the rolling tremor. Some folks in Vegas said on social media they felt it too.
At the epicenter in Ridgecrest, CA ... items toppled off shelves and mirrors came crashing down. The National Weather Service said no tsunami warnings are expected in California, Oregon or Washington. There are no reports of any structural damage to buildings or roads ... at least not yet.
