The National Earthquake Hazards Reduction Program (NEHRP): Issues in Brief

The National Earthquake Hazards Reduction Program (NEHRP): Issues in Brief. Congressional Research Service, Library of Congress. Peter Folger. December 3, 2018

Portions of all 50 states and the District of Columbia are vulnerable to earthquake hazards, although risks vary greatly across the country and within individual states. Alaska is the most earthquake-prone state, experiencing a magnitude 7 earthquake almost every year and a magnitude 8 earthquake every 13 years, on average, since 1900. On December 1, 2018, a magnitude 7.0 earthquake struck north of Anchorage at 8:29 AM local time, causing extensive damage. Under the National Earthquake Hazards Reduction Program (NEHRP), four federal agencies have responsibility for long-term earthquake risk reduction: the U.S. Geological Survey (USGS), the National Science Foundation (NSF), the Federal Emergency Management Agency (FEMA), and the National Institute of Standards and Technology (NIST). These agencies assess U.S. earthquake hazards, deliver notifications of seismic events, develop measures to reduce earthquake hazards, and conduct research to help reduce overall U.S. vulnerability to earthquakes. Congressional oversight of the NEHRP program encompasses how well the four agencies coordinate their activities to address the earthquake hazard. Better coordination was a concern that led to changes to the program in legislation enacted in 2004 (the National Earthquake Hazards Reduction Program Reauthorization Act of 2004; P.L. 108-360; 42 U.S.C. 7704).
