USGS Earthquake Hazard Toolbox

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 USGS Earthquake Hazard Toolbox (https://earthquake.usgs.gov/nshmp) web application 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 and 2023 conterminous U.S. NSHMs, the 2021 NSHM for the State of Hawaii, and the 2023 NSHM for the State of Alaska with additional older NSHMs to be added soon. One advantage of recent improvements to the USGS hazard modeling codebase is that models under development 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 forecasts, include a magnitude-frequency distribution plotter and a source data mapping application. Each application is backed by web services that permit the underlying calculations and data to be easily accessed via third-party applications (e.g., MATLAB, Python, R). Moreover, each application provides export options to save any plot data in tabular form and plots as static images. Here we provide an overview of the various USGS Earthquake Hazard Toolbox applications, as well as examples of how to leverage the suite of underlying web services.
