2009 Earthquake Probability Mapping
This web site was designed to display earthquake probabilities that are computed from the source model of the 2008 USGS-National Seismic Hazard Mapping Project (NSHMP) update. The region of model validity is the conterminous (lower 48 states) USA and Alaska. Valid locations in the conterminous 48 states range from [24.6, 50.0] degrees latitude and [-125.0, -65.0] degrees longitude. Valid locations in Alaska range from [50.0, 72.0] degrees latitude and [-200.0, -125.0] degrees longitude.
The generated maps will show the probabilities of earthquakes within a radius of 50 km. A text report of the probabilities for a different, selected radius can also be generated.
