Interagency Earthquake Committee is an interagency coordination body formed to harmonize seismic research, monitoring, preparedness, and response among federal, state, and international institutions. It convenes experts from scientific agencies, emergency management offices, and engineering bodies to produce standards, protocols, and operational guidance. The Committee acts as a clearinghouse linking research programs, instrumentation networks, and policy instruments to reduce seismic risk and improve resilience.

History

The Committee traces roots to post‑World War II civil defense initiatives influenced by discussions involving National Academy of Sciences, United States Geological Survey, National Research Council (United States), Federal Emergency Management Agency, and academic centers such as California Institute of Technology and Massachusetts Institute of Technology. During the 1960s and 1970s, interactions among United States Geological Survey, United States Department of the Interior, National Science Foundation, and state seismic advisory bodies led to formalized coordination similar to arrangements between National Oceanic and Atmospheric Administration, United States Geological Survey, and regional seismic networks after major events like the 1964 Alaska earthquake and the 1989 Loma Prieta earthquake. Subsequent evolution involved engagement with United Nations Office for Disaster Risk Reduction, World Bank, and multinational research consortia following lessons from the 1995 Kobe earthquake and the 2004 Indian Ocean earthquake and tsunami.

Membership and Organization

Membership typically includes representatives from United States Geological Survey, Federal Emergency Management Agency, National Aeronautics and Space Administration, National Science Foundation, Department of Homeland Security, National Institute of Standards and Technology, and state agencies such as California Governor's Office of Emergency Services and Alaska Division of Geological & Geophysical Surveys. Academic partners often include Stanford University, University of California, Berkeley, Seismological Society of America, and international institutes such as British Geological Survey and Geological Survey of Japan. Technical working groups draw participants from Pacific Northwest Seismic Network, Southern California Seismic Network, Incorporated Research Institutions for Seismology, ComCat (USGS) contributors, and specialist organizations like American Society of Civil Engineers and Earthquake Engineering Research Institute. Organizationally the Committee forms steering committees, scientific panels, and operational task forces mirroring structures used by National Incident Management System and interagency bodies such as Interagency Wildland Fire Policy Committee.

Roles and Responsibilities

The Committee’s responsibilities include coordinating seismic hazard assessment collaborations among United States Geological Survey hazard maps, interoperability standards promoted by National Institute of Standards and Technology, and building code inputs from International Code Council. It facilitates joint initiatives with Federal Emergency Management Agency mitigation programs, supports post‑event scientific response similar to USGS–CGS joint rapid response, and advises legislators alongside committees of the United States Congress and agencies like Office of Science and Technology Policy. The Committee also liaises with international partners such as Global Seismographic Network stakeholders, International Seismological Centre, and United Nations Educational, Scientific and Cultural Organization to align cross‑border protocols.

Research, Monitoring, and Data Sharing

The Committee fosters multi‑agency research linking observational networks like Global Seismographic Network, USArray, and regional arrays operated by California Institute of Technology and University of Washington, with modeling groups at Lawrence Berkeley National Laboratory and Los Alamos National Laboratory. It promotes data interoperability through standards from Incorporated Research Institutions for Seismology, metadata policies of National Centers for Environmental Information, and program coordination with EarthScope initiatives. Collaborative projects have included ground motion prediction studies involving Pacific Northwest National Laboratory, seismic hazard modeling used by Federal Highway Administration, and early warning system development coordinated with ShakeAlert partners and U.S. Geological Survey networks. The Committee recommends data sharing agreements compatible with protocols used by International Federation of Red Cross and Red Crescent Societies and research funders such as National Science Foundation.

Emergency Response and Preparedness

In emergencies the Committee integrates scientific advisory roles with operational response frameworks used by Federal Emergency Management Agency, Department of Homeland Security, and state emergency management agencies. It supports incorporation of rapid scientific assessments produced by USGS Earthquake Hazards Program, field reconnaissance coordinated with American Society of Civil Engineers reconnaissance teams, and damage‑assessment methods informed by FEMA Hazus modeling. The Committee has promoted joint exercises with National Guard units, coordinated communications pathways compatible with National Incident Management System and Incident Command System, and helped structure mutual aid agreements akin to those employed by Emergency Management Assistance Compact.

Policy, Standards, and Public Communication

The Committee develops policy recommendations influencing building codes administered by International Code Council and standards from American Society of Civil Engineers, and it advises National Institute of Standards and Technology on performance objectives. It issues guidance for risk communication drawing on practices from Centers for Disease Control and Prevention crisis messaging and public outreach strategies used by United States Geological Survey and Federal Emergency Management Agency. Public education collaborations have included museums and outreach partners such as Smithsonian Institution and California State University systems to improve community resilience. The Committee also engages with lawmakers in the United States Congress and international policy forums such as World Conference on Disaster Risk Reduction to embed scientific consensus into legislation and international agreements.
