A light earthquake rattled Southern California early Thursday morning in the latest sign of seismic activity this week along the "Ring of Fire," but the shaking did not result in any reports of damage or injuries.
The United States Geological Survey said the quake, with a magnitude of 4.0, occurred just after 2 a.m. Thursday about 31 miles southeast of Anaheim.
The quake had a depth of about six miles, according to the USGS. The Orange County Sheriff's Office told The Associated Press there have been no reports of damage or injury.
