Summary
The Open Seismic Hazard Analysis is an effort to develop object-oriented, web and GUI-enabled, open-source, and freely available code for conducting Seismic Hazard Analyses (SHA).

Our goal is to provide a framework where any arbitrarily complex (e.g., physics based) earthquake-rupture forecast, ground-motion, or engineering-response model can "plug in" for analysis without ... having to change what's being plugged into.

Although some applications will be stand alone, our goal is also to enable the various SHA components to be geographically distributed over the Internet in what we term a "community modeling environment", all tied together with a user-friendly web interface.

This infrastructure should significantly reduce the gap between cutting-edge geophysics and state-of-the-art hazard and risk evaluations.

Specifically, the mean, standard deviation, probability of exceeding a given IML, or the IML that has a given probability of exceedance can can be plotted (on the Y-axis) as a function of whatever independent parameters the Attenuation Relationship depends upon. Any independent parameter that represents a numerical value can be used for the X axis.
