Incorporating Induced Seismicity in the 2014 United States National Seismic Hazard Model: Results of 2014 Workshop and Sensitivity Studies U.S. Geological Survey

Incorporating Induced Seismicity in the 2014 United States National Seismic Hazard Model: Results of 2014 Workshop and SensThe U. S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) for the conterminous United States was updated in 2014 to account for new methods, input models, and data necessary for assessing the seismic ground shaking hazard from natural (tectonic) earthquakes. The USGS NSHM project uses probabilistic seismic hazard analysis to quantify the rate of exceedance for earthquake ground shaking (ground motion). For the 2014 NSHM assessment, the seismic hazard from potentially induced earthquakes was intentionally not considered because we had not determined how to properly treat these earthquakes for the seismic hazard analysis. The phrases "potentially induced" and "induced" are used interchangeably in this report, however it is acknowledged that this classification is based on circumstantial evidence and scientific judgment.
