The 1994 Northridge earthquake affected the Los Angeles area of California on January 17, 1994, at 04:30:55 PST. The epicenter of the moment magnitude 6.7 (Mw) blind thrust earthquake was beneath the San Fernando Valley.[3] Lasting approximately 8 seconds and achieving the largest peak ground acceleration of over 1.7 g, it was the largest earthquake in the area since 1971. Shaking was felt as far away as San Diego, Turlock, Las Vegas, Richfield, Phoenix, and Ensenada.[4] Fifty-seven people died and more than 9,000 were injured.[5][6] In addition, property damage was estimated to be $13–50 billion, making it among the costliest natural disasters in U.S. history.[7][8]
