Hazus Quick Reference Guide

This page provides quick reference information on the Hazus software, including downloading Hazus, system requirements, available user guidance materials and trainings, where to get assistance and how to stay connected and up-to-date on Hazus news.

Hazus is a nationally applicable standardized methodology that contains models for estimating potential losses from earthquakes, floods, hurricanes, and tsunamis. Hazus uses Geographic Information Systems (GIS) technology to estimate physical, economic and social impacts of disasters. Users can then visualize the spatial relationships between populations and other more permanently fixed geographic assets or resources for the specific hazard being modeled, a crucial function in the pre-disaster planning process.
