Biggest Quake in 20 Years Hits Southern California On Fourth Of July

On Thursday, the largest earthquake to hit Southern California in roughly 20 years rumbled from 125 miles northeast of Los Angeles.

The 6.4 magnitude earthquake, the biggest in Southern California since the magnitude 7.1 Hector Mine quake hit the Mojave Desert in 1999, struck at roughly 10:30 a.m. and was felt as far away as Las Vegas, Nevada, Reno, Nevada, Phoenix, Arizona, and Ensenada and Mexicali in Mexico. As The Los Angeles Times noted, a 5.4 magnitude aftershock awakened many people Friday morning.
