This page discusses FEMA's Hazus program and related news updates. This page is intended for Hazus users and other parties interested in using Hazus to support risk-informed decision making efforts by estimating potential losses from earthquakes, floods, hurricanes, and tsunamis and visualizing the effects of such hazards.
Have any interesting Hazus research or success stories to share? Want to get involved with the Hazus program by attending the monthly National Hazus User Group call? Reach out to the Hazus Outreach Team at email@example.com with questions, comments, or to be added to the monthly call invitation.
Service Pack 1 for Hazus 4.2: Service Pack 1 for Hazus 4.2 was released on May 25, 2018. This update enhances usability and utility of Hazus 4.2 by fixing latent bugs, enhancing hazard methodologies, and improving import and export processes. Get more details on this update at the Hazus Releases page, and download the executable on FEMA’s Map Service Center.
Hazus: FEMA's Methodology For Estimating Potential Losses from Disasters
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, flood, and tsunami. 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. Hazus can be used in the assessment step in the mitigation planning process, which is the foundation for a community's long-term strategy to reduce disaster losses and break the cycle of disaster damage, reconstruction, and repeated damage. Being ready will aid in recovery after a natural disaster.
Potential loss estimates analyzed in Hazus include:
- Physical damage to residential and commercial buildings, schools, critical facilities, and infrastructure;
- Economic loss, including lost jobs, business interruptions, repair, and reconstruction costs;
- Social impacts, including estimates of shelter requirements, displaced households, and population exposed to scenario floods, earthquakes, and hurricanes, and tsunamis
As the number of Hazus users continues to increase, so do the types of uses. Increasingly, Hazus is being used by states and communities in support of risk assessments that perform economic loss scenarios for certain natural hazards and rapid needs assessments during hurricane response. Other communities are using Hazus to increase hazard awareness.
