The Northrige earthquake occurred on January 17, 1994 at 4:31 AM Pacific Standard Time in Reseda, a neighborhood in the city of Los Angeles, California. The earthquake had a "strong" moment magnitude of 6.7, but the ground acceleration was the highest ever instrumentally recorded in an urban area in North America. 72 people died as a result of the earthquake and over 12,000 were injured. In addition, the earthquake caused an estimated $12.5 billion in damage, making it one of the costliest natural disasters in U.S. history.
