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 and hurricanes and visualizing the effects of such hazards.
The Federal Emergency Management Agency's (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 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. 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.
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. Successful uses of Hazus are profiled under Mitigation and Recovery and Preparedness and Response. Emergency managers have also found these map templates helpful to support rapid impact assessment and disaster response.
As part of a major effort to modernize Hazus, a number of updates are in progress. In late 2014, an update will be released to bring Hazus up to compatibility with ArcGIS 10.2.2 and Windows 8. Later in the Hazus Modernization process, new functional enhancements will be implemented in the flood module and the underlying code of Hazus will be re-architected to align with current practices, enabling future development.

Hazus software is a powerful risk assessment methodology for analyzing potential lossesfrom floods, hurricane and earthquakes. In Hazus, current scientific and engineering knowledge is coupled with the latest geographic information systems (GIS) technology to produce estimates of hazard-related damage before or after a disaster occurs.
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; and
- Social impacts, including estimates of shelter requirements, displaced households and population exposed to scenario floods, earthquakes and hurricanes

Users can also call the FEMA Map Information Exchange (FMIX) at 1-877-336-2627 as an alternative means of support. The FMIX gives Hazus users the ability to speak directly with a support representative during normal business hours to follow up on Help Desk tickets, receive assistance in using the Help Desk or get answers to general questions about Hazus.
Federal, state and local government agencies and the private sector can download the latest version of Hazus free-of-charge online by visiting the FEMA Flood Map Service Center (MSC).
The online download option is only available to U.S. users. International users will continue to order a Hazus DVD by contacting the FEMA Map Information eXchange (FMIX) at 1-877-336-2627 or FEMAMapSpecialist@riskmapcds.com.
