Summary

Probabilistic seismic-hazard maps were prepared for the conterminous United States that portray peak horizontal acceleration and horizontal spectral response acceleration for 0.2, 1.0, and 5.0 second periods with a probability of exceedance of 2%, 5%, and 10% percent in 50 years. Maps and data are available for NEHRP site class B/C and D (Vs30 equal to 760 m/s and 260 m/s). This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude.
