# Documentation: nshmp-haz

***nshmp-haz*** is a USGS developed software stack that supports probabilistic seismic hazard
(PSHA) and related analyses. It is maintained by the National Seismic Hazard Model Project
([NSHMP](https://earthquake.usgs.gov/hazards/)) within the U.S. Geological Survey's
([USGS](https://www.usgs.gov)) earthquake hazards program ([EHP](http://earthquake.usgs.gov)).

*nshmp-haz* supports high performance seismic hazard calculations required to generate detailed
maps over large areas and supports a variety of USGS web services and applications related to
seismic hazards research and the dissemination of hazard data. This documentation explains how
to use *nshmp-haz* as well as underlying model implementation details.
