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. This particular data set is for horizontal spectral response acceleration for 0.2second period with a 1 percent probability of exceedance in 1 year. The data are for the Western United States and are based on the longterm 2014 National Seismic Hazard Model.

These data sets are the results of calculations of hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude. They represent the chance of experiencing potentially damaging ground shaking for fixed ground shaking levels that corresponds with MMI = VII. The values are obtained by averaging the probability of experiencing MMI = VII based on a peak ground acceleration value of 0.2152 g for site class D, and the probability of experiencing MMI = VII based on 1.0second spectral acceleration value of 0.2256 g for site class D. The data are for the Central and Eastern United States.

This dataset provides location information for the seismic reflection line CRmv across Crowleys Ridge in the New Madrid seismic zone, central US. The seismic reflection data are interpreted and discussed in the associated publication

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. It represents the average Modified Mercalli Intensity (MMI) with a 1percent probability of exceedance in 1 year. Using a topographicbased soil classification method, the ground motions are amplified for soil type. The MMI values are the average of the MMI values obtained by converting peak ground acceleration to MMI and 1.0second spectral response acceleration to MMI. The data are for the Western United States and are based on the longterm 2014 National Seismic Hazard Model.
