Earthquake Country Alliance, Bay Area

Earthquake Country Alliance Bay Area (ECA Bay Area) 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.

Earthquake Country Alliance Bay Area is the new name of the Bay Area Earthquake Alliance (which was founded in 2009 by the USGS as an ECA Regional Alliance). The new name better indicates the relationship with the statewide organization and helps to standardize branding and messaging.

We encourage you to Join the Alliance
