Summary

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 chance of experiencing damaging earthquakes for fixed ground shaking levels that corresponds with MMI = VI. The values are obtained by averaging the probability of experiencing MMI = VI based on a peak ground acceleration value of 0.1155 g for site class D, and the probability of experiencing MMI = VI based on 1.0-second spectral acceleration value of 0.102 g for site class D. The data are for the Western United States and are based on the long-term 2014 National Seismic Hazard Model.

Purpose

This map is intended to provide a more robust estimate for the chance of experiencing damage from an earthquake by averaging the probabilities obtained from peak ground acceleration hazard curves and hazard curves for 1.0-second spectral response acceleration.
