Hazards - United States (Hazus)
Hazards-United States (Hazus) is a nationally applicable standardized methodology that contains models for estimating potential losses from earthquakes, floods, and hurricanes. Hazus uses Geographic Information Systems (GIS) technology to estimate physical, economic, and social impacts of disasters. It graphically illustrates the limits of identified high-risk locations due to earthquake, hurricane, and floods. 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.
Hazus is used for mitigation and recovery as well as preparedness and response. Government planners, GIS specialists, and emergency managers use Hazus to determine losses and the most beneficial mitigation approaches to take to minimize them.
Also, the methodology is being used by states and communities in support of risk assessments perform economic loss scenarios for certain natural hazards and rapid needs assessments during hurricane response. Other communities are using Hazus to increase hazard awareness. Successful uses of Hazus are profiled under 'Mitigation and Recovery' and 'Preparedness and Response' on the FEMA website. These map templates are helpful to emergency managers in supporting rapid impact assessment and disaster response.
Hazus can be used to estimate social and economic damage, in addition to physical damage. The tool draws on census block level information to show demographic details including income, population, and housing units. It also includes indirect economic data to understand the post-disaster change in demand and supply of products, changes in employment, and changes in tax revenues.
