Earthquake in Southern California

Despite shaking a large swath of Southern California, a magnitude-5.4 earthquake was not the "Big One" that scientists have long feared. Still, it rattled nerves, causing people to vow to step up their emergency preparations.

The quake, which rocked the region from Los Angeles to San Diego on Tuesday, caused only limited damage and minor injuries, and served as a reminder of the seismic danger below sprawling freeways and subdivisions.

The temblor's epicenter was located just outside Chino Hills, 29 miles southeast of downtown Los Angeles in San Bernardino County, and it was felt as far east as Las Vegas. Dozens of aftershocks followed, the largest a magnitude-3.8.

"It's a drill for the Big One that's going to happen someday."

The Judge Judy cameras caught more than just courtroom drama today after a massive earthquake hit Southern California.

The Judge Judy set, at the Paramount lot in Hollywood, was full of audience members and case-participants when the earthquake struck. The cameras kept rolling the entire time.

Kudos to the plaintiff who clearly cares more about the US Justice System than her own life, as she stayed in place during the quake.
