Summary

A one-year seismic hazard forecast for the Central and Eastern United States, based on induced and natural earthquakes, has been produced by the U.S. Geological Survey. The model assumes that earthquake rates calculated from several different time windows will remain relatively stationary and can be used to forecast earthquake hazard and damage intensity for the year 2016. This assessment is the first step in developing an operational earthquake forecast for the CEUS, and the analysis could be revised with updated seismicity and model parameters. Consensus input models consider alternative earthquake catalog durations, smoothing parameters, maximum magnitudes, and ground motion estimates, and represent uncertainties in earthquake occurrence [...]

Purpose

This map is intended to provide a more robust estimate of Modified Mercalli Intensity (MMI) with a 1-percent probability of exceedance in 1 year, by averaging the MMI values obtained from peak ground acceleration hazard curves and hazard curves for 1.0-second spectral response acceleration.
