ECA Southern California

Earthquake Country Alliance Southern California (ECA SoCal) is one of three regional alliances that comprise the statewide Earthquake Country Alliance, a public-private-grassroots partnership of leading earthquake professionals, emergency managers, government officials, business and community leaders, and others.

ECA is best known for coordinating the annual Great California ShakeOut earthquake drill and developing multi-sector educational resources.

Funding for ECA activities is provided by FEMA’s Building Science Branch as part of its support for the California Governor’s Office of Emergency Services Earthquake Program.

Among the many partners in ECA SoCal are the Southern California Earthquake Center, U.S. Geological Survey, Caltech, California Earthquake Authority, California Office of Emergency Services, FEMA, California Geological Survey, County of Los Angeles, County of San Bernardino, City of Los Angeles, MySafe:LA, Providence Health Care, and the American Red Cross.

We encourage you to Join the Alliance
