As an object-oriented framework, OpenSHA can accomodate arbitrarily complex (e.g., physics based) earthquake rupture forecasts (ERFs), ground-motion models, and engineering-response models, which narrows the gap between cutting-edge geophysics and state-of-the-art hazard and risk evaluations.

Like many open-source projects (see license), OpenSHA is a work in progress. Over twenty years in development, the project has been touched by numerous scientists, developers, and technical experts in the fields of seismology, computer science, and earthquake engineering.
Although primarily focused on California at inception, OpenSHA is now seeing broader, national use via incorporation in the National Sesmic Hazard Mapping (NSHMP) at the USGS, and it is receiving global exposure via the GEM project.
Much of the development of OpenSHA would not have been possible without dedicated financial support of various sponsors.
