USGS NSHM Hazard Tool

Description: 

The U.S. Geological Survey (USGS) earthquake hazards website provides web services and applications that give users access to the National Seismic Hazard Models (NSHMs) for the United States and its territories. The NSHM Hazard Tool (https://earthquake.usgs.gov/nshmp) is the main entry point for end-users to calculate hazard and to query data for various USGS NSHMs. The tool currently supports the 2018 conterminous U.S. NSHM and the 2021 NSHM for the State of Hawaii with additional older NSHMs to be added soon. One advantage of recent improvements to the USGS hazard modeling codebase is that models currently under development (e.g., the 2023 NSHMs for the conterminous U.S. and Alaska) can be deployed to the tool for earlier end-user evaluation and adoption. In addition to providing web applications for hazard calculation and disaggregation, the NSHM hazard tool also provides model analysis applications. Applications for working with ground motion models include the response spectrum plotter and ground motion versus distance or magnitude plotters. Applications for working with source models, or earthquake rupture forecast, include a magnitude-frequency distribution plotter and a source data mapping application. All the web applications are backed by services such that the underlying data may be easily accessed via third-party applications (e.g., MATLAB, R). Moreover, each application provides export options to save any plot data in tabular form. Here we provide an overview of the various NSHM Hazard Tool applications, as well as examples of how to leverage the suite of underlying web services.
