Operationalizing the use of millennial-scale geologic constraints for testing and improving modern seismic hazard models
This Powell Center working group will improve the National Seismic Hazard Model by developing and operationalizing the first comprehensive set of geologic data on past earthquake shaking intensity.
Society needs information about the danger from earthquake ground shaking to make decisions about infrastructure investments, engineering designs, and public safety. The U.S. National Seismic Hazard Model provides this information by forecasting the probability of damaging levels of shaking. Forecasts show that nearly all U.S. states include areas of moderate or high earthquake hazard.
This Powell Center working group will improve the National Seismic Hazard Model by developing and operationalizing the first comprehensive set of geologic data on past earthquake shaking intensity. Geologic data provide the only direct evidence of typical shaking during larger earthquakes at most places. With these data and a workflow to implement them, the working group will provide the means to test National Seismic Hazard Model forecasts and improve the underlying ground motion models, thereby making society safer.
