Updated Seismic Hazard Model Reveals Increased Earthquake Risk Across U.S.

New findings indicate potential for more damaging earthquakes in Atlantic Coastal corridor and greater shaking in California, Alaska, and Hawai'i.

Nearly 75% of the U.S. could experience damaging earthquake shaking, according to the updated National Seismic Hazard Model (NSHM) by the U.S. Geological Survey.
The new model identifies nearly 500 additional faults that could produce a damaging quake, showcasing the evolving landscape of earthquake research.
Significant changes in the new model show the possibility of more damaging earthquakes along the central and northeastern Atlantic Coastal corridor, including in the cities of Washington D.C., Philadelphia, New York, and Boston.
There is a chance for greater shaking in the seismically active regions of California and Alaska, and Hawai'i is characterized as having greater potential for shaking due to recent volcanic eruptions and seismic unrest.
The updated model will inform the future of building and structural design, offering critical insights for architects, engineers, and policymakers on how structures are planned and constructed across the U.S.
