Underlying Data Sets For Seismic Design Calculator

These files are used by the Java Ground Motion Parameter Calculator to generate hazard curves and ground motion values for the Conterminous 48 States, Alaska, Hawaii, Puerto Rico, and the Virgin Islands. Click a column header to re-sort data by that column in order to find the particular file for which you are looking. Zip code data files can be found here. See our discussion on binary file formats for more information about how to read/parse the various binary file formats.
