The Alliance

Our Purpose

What we do to prepare now,
before the next disaster,
will determine our
quality of life afterwards

Everywhere in California can experience damaging earthquakes. While much has been done to prepare, more is needed.

Those of us committed to improving earthquake safety and reducing risk must find new ways to inspire all Californians to take responsibility and act now to increase resiliency. This is how Californians will not only survive the next big disaster, but get our lives, neighborhoods and businesses back on track quickly.

None of us can do this alone. Creating a culture of resiliency for all Californians depends on leveraging our efforts and sharing our strengths.

The purpose of the Earthquake Country Alliance (ECA) is to facilitate these efforts. ECA is a statewide public-private partnership of people, organizations, and regional alliances that work together to improve preparedness, mitigation and resiliency.


Our Organization

ECA began in 2003 in Southern California and expanded statewide in 2009 in partnership with the Earthquake Country Alliance Bay Area (originally “Bay Area Earthquake Alliance”) and the Redwood Coast Tsunami Work Group. Other regional alliances may join the ECA in the future representing other parts of the state.

Each regional alliance conducts its own activities and collaborates with the others via the statewide ECA, which is administered by the Southern California Earthquake Center at USC. Statewide committees determine sector-based needs and develop resources. ECA is best known for coordinating the annual Great California ShakeOut earthquake drill and developing multi-sector educational resources on this website.

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.


To support and coordinate efforts which improve earthquake and tsunami resilience.


  • People of California take active steps to ready and protect themselves, their families, their businesses, and their communities for earthquakes and tsunamis
  • People of California perpetuate a self sustaining culture of readiness and resiliency by sharing their readiness and mitigation activities with one another
  • A robust network of public and private stake holder organizations, regional alliances, and individuals effectively coordinate earthquake education efforts that inspire the people of California to stay ready and resilient


Strategic Partner Organizations:
