Earthquakes Hazards


two maps os the U.S.

Map showing the 1‐year chance of minor (top) and moderate (bottom) damaging earthquake shaking in the United States in 2018. Hazard from the western United States from the 2014 National Seismic Hazard Maps (Petersen et al., 2014) is shown on the left of both maps for comparison. (Public domain.)

Induced Earthquakes
Current research on induced earthquakes due to human activities. Observations, modeling, and hazards.

Earthquake Early Warning
A few seconds matter. USGS has been working to develop earthquake early warning for the United States.

Faults, Earthquake Geology, and Special Earthquake Studies
The study of active fault zones, and collections of information for specific significant earthquakes.

To mitigate earthquake losses, scientists evaluate the earthquake hazards across the country.

Earthquake Processes and Effects
Crustal deformation, ground motion, ground failure, and the effects of earthquakes.

Monitoring Improvements
Scientists are doing research to improve earthquake monitoring, detection and analysis.

External Grants
The USGS supports external research that will assist in achieving the goals of the National Earthquake Hazards Reduction Program (NERHP).
