We all must get better prepared for major earthquakes, and practice how to protect ourselves when they happen. The purpose of ShakeOut is to help people and organizations do both.
The Great California ShakeOut is made possible by generous support of several sponsors, committed organizers from many organizations, the encouragement of many others, and a growing legion of active ECA Associates throughout the state that share the ShakeOut locally.
The Great California ShakeOut is organized by key members of the Earthquake Country Alliance:
Southern California Earthquake Center
United States Geological Survey
California Governor's Office of Emergency Services
California Earthquake Authority
