AB: OpenSHA (http://www.OpenSHA.org) is an object-oriented, open-source, and web-based "community modeling environment" for seismic-hazard analysis (SHA). A primary goal has been to enable any arbitrarily sophisticated (e.g., physics-based) model to "plug in" for analysis without having to change what is being plugged into; that is, without rewriting existing code. Another goal has been to enable the models, as well as the various data repositories upon which they depend, to be geographically distributed and run-time accessible via the Internet. Building such a community-modeling environment has raised several issues related to computational speed, ease of use, error prevention, and repeatability of results in an environment where the models and data are continually being updated. The Information Technology Research collaboration of the Southern California Earthquake Center (http://www.SCEC.org/cme) is helping us resolve some of these issues. Our presentation will include live demonstrations of the framework using applications we've developed for computing hazard curves, hazard maps, and scenario ShakeMaps.
