There are drills, and then there are drills. At 10 a.m. on November 13th 2008, more than 5 million people throughout Southern California participated in the ShakeOut Drill, the largest earthquake preparedness activity in U.S. history. The Great Southern California ShakeOut is based on a potential magnitude 7.8 earthquake on the southern San Andreas Fault. This is approximately 5,000 times larger than the magnitude 5.4 earthquake that shook southern California on July 29.
The ShakeOut was held concurrently with Golden Guardian 2008, the US’s largest state sponsored emergency response exercise, involving 5,000 participants from dozens of state, local, and federal agencies.
