Open Seismic Hazard Analysis logoThe primary goal of OpenSHA is to improve Seismic Hazard Analysis by providing a platform that can accommodate both past and future models. To this end, OpenSHA is object-oriented, web- & GUI-enabled, open-source, and freely available. The goal is to provide a framework where any arbitrarily complex (e.g., physics based) Earthquake Rupture Forecast, ground-motion model, or engineering-response model can “plug in” for analysis without having to change what’s being plugged into.
