seismic map
This map shows areas of equal seismic hazard and indicates the minimum peak horizontal ground acceleration value, a measure of the how hard the ground shakes in a given area.

The map also shows locations of the 63 US nuclear power plants. The data comes from the US Geological Survey Geological Hazards Team and the US Energy Information Administration. Shapefiles provided by Michael Meuser, http://www.mapcruzin.com/nuclear-power-plant-earthquake-shapefiles/
