To download the Hazus User and Technical Manuals for the Earthquake, Hurricane, Flood, and Tsunami models, or to view additional Hazus manuals and release notes, please visit our Hazus User & Technical Manuals archive page. The User Manuals are designed to support model functionality, while the Technical Manuals provide detailed information about how the models work and how to generate loss estimates.
Hazus Earthquake Manuals
The Hazus Earthquake User and Technical Manuals provide detailed information on how the model calculates damage and loss estimates to buildings, essential facilities, transportation, utility lifelines, and population based on real-time, scenario, or probabilistic earthquakes. Additionally, they address debris generation, fire-following, casualties, and shelter requirements design and calculations. Direct losses are estimated based on physical damage to structures, contents, inventory, and building interiors. The earthquake model includes the Advanced Engineering Building Module for single- and group-building analysis.
Hazus Hurricane Manuals
The Hazus Hurricane Wind User and Technical Manuals provide information on the model outputs, uncertainties, running basic and advanced analyses, damage functions, debris generation, shelter requirements, storm surge, and impacts such as direct economic loss and building damage. The Technical Manual also includes validation studies for historical hurricanes. The Hazus Hurricane Wind Model provides improvements over existing loss estimation models because of the wind hazard-load-damage-loss framework.
Hazus Flood Manuals
The Hazus Flood User and Technical Manuals provide guidance on Flood hazard and analysis, methodology, inventory requirements (including inventory updates), running basic and advanced analyses, results, and how to interpret loss estimates. Specific outputs include damage to building stock, lifelines, economic losses, and much more. The flood loss estimation methodology consists of two modules that carry out basic analytical processes: flood hazard analysis and flood loss estimation analysis. The flood hazard analysis module uses characteristics, such as frequency, discharge and ground elevation to estimate flood depth, flood elevation and flow velocity. Users also have the ability to directly import user-defined flood hazard depth grids in multiple forms. The flood loss estimation module calculates physical damage and economic loss from the results of the hazard analysis. Both coastal and riverine information is covered in these manuals.
Hazus Tsunami Manuals
The Hazus Tsunami User and Technical Manuals provide insight into the tsunami loss estimation methodology, inventory data specifications, running hazard analyses, and outputs for damage assessments, casualty estimation, and direct economic losses. The Hazus Tsunami Model provides practitioners and policy makers with a tool to help reduce tsunami damage, reduce disaster payments, and make wise use of the nation’s emergency management resources for 5 very high-risk states and five high risk U.S. territories: Alaska, Washington, Oregon, California, Hawaii, Northern Mariana Islands, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands.
