Probabilistic seismic-hazard maps were prepared for the Central and Eastern United States, as well as the Western United States. These maps portray peak horizontal acceleration and horizontal spectral response acceleration for 0.2- and 1.0-second periods with a probability of exceedance of 1 percent in 1 year. 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.
