The Earthquake Country Alliance (ECA) is a recently-expanded statewide "alliance of alliances" linking the public information efforts of organizations and individuals that provide earthquake information and services. Participants include the Bay Area Earthquake Alliance, the Redwood Coast Tsunami Workgroup, and the Southern California Earthquake Alliance (new "internal" name of the original ECA). Other regional alliances may join the ECA in the future representing areas such as the Central Coast, Lake Tahoe/Reno, and other parts of the state.

ECA members include: scientists and engineers; non-profit organization and business leaders; community groups and activists; federal, state, and local government leaders and agencies; tribes; and others who share a passion for making a difference towards reducing California's earthquake risk. The slogan of the ECA is We're All in This Together and now extends statewide. Soon earthquakecountry.info will be updated to provide a one-stop source for regional alliance activities and general earthquake preparedness, mitigation, and safety information through its related websites daretoprepare.org, dropcoverholdon.org, terremotos.org (Spanish information), and of course ShakeOut.org.

The ECA is intended to help coordinate the earthquake information materials and programs of organizations with related missions and activities, so that the public receives information that is consistent, from multiple sources they trust, through multiple channels, and serves all California residents.

Mission
The Earthquake Country Alliance unites leaders in government, disaster response, science, business, media, education and local communities to:

• inspire responsibility for community earthquake safety and recovery;
• increase awareness, preparedness, mitigation;
• improve response and recovery planning;
• reduce losses in future earthquakes.
