nshmp-haz-ws is a web-service wrapper around the nshmp-haz probabilistic seismic hazard analysis (PSHA) platform. It is developed and maintained by the National Seismic Hazard Mapping Project (NSHMP) within the U.S. Geological Survey's (USGS) earthquake hazards program (EHP).

nshmp-haz-ws services supply data to the USGS NSHMP Unified Hazard Tool (UHT). While basic documentation on the use of the tool is available here, this documentation describes the details of the underlying data and calculations, including descriptions or examples of:

• How to run hazard and deaggregation services locally.
• The different editions of the hazard models the NSHMP produces and their distinguidhing features.
• Static vs. dynamic data.
• Common use cases.
