The OpenQuake Engine software provides calculation and assessment of seismic hazard, risk and decision-making tools via the data, methods and standards that are being developed by GEM (Global Earthquake Model) and its collaborators.
The seismic hazard calculations of the OpenQuake Engine are powered by the OpenQuake Hazard Library and OpenQuake Risk Library Both libraries were built by the OpenQuake team to serve as a fast, stable, and lightweight alternative to existing risk and hazard libraries.
To get involved in OpenQuake, join us on IRC (irc.freenode.net) in the #openquake channel by using an IRC client or via web at http://webchat.freenode.net. You can also submit questions, comments, or support requests to our OpenQuake users mailing list: http://groups.google.com/group/openquake-users.
