earthquake on triggered ,4 aftershocks Southern California

An earthquake that triggered a series of aftershocks in Orange County on Wednesday night wasn't quite as strong as initially thought.

Originally reported as a magnitude 4.1 temblor that hit about 8:17 p.m. near Yorba Linda, the U.S. Geological Survey later downgraded it to a magnitude 4 quake.

No damage was immediately reported after the earthquake or the four aftershocks that followed, Orange County officials said. The aftershocks included two magnitude 2.4 temblors that were about two miles north and north-northwest of Yorba Linda, according to the USGS.

The quake was felt over a wide area of Los Angeles and Orange counties, and added a little extra excitement to the star-studded red-carpet opening of the new Cars Land at the Disneyland Resort.

Thousands of people -- celebrities, media and other invitation-only guests -- were gathered at Disney's California Adventure for an event celebrating the final piece of a $1.1-billion expansion of the Anaheim park.

"Earthquake!" @Mouseinfo tweeted. "I guess mother nature wanted to get into #carsland too."
