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

Federal, state and local government agencies and the private sector can download the latest version of Hazus and state datasets free-of-charge online by visiting the FEMA Flood Map Service Center (MSC) at msc.fema.gov.
The online download option is only available to U.S. users. International users interested in Hazus should contact FEMA’s International Affairs Division at FEMA-International@dhs.gov.
Orders placed by non U.S. residents typically require more time to process than normal due to the need to obtain special FEMA approval.
Requests for older versions of Hazus can be made by contacting the FEMA Map Information eXchange (FMIX) at:
Telephone: 1-877-FEMA-MAP (1-877-336-2627)
The latest Service Pack (SP) release is Hazus-MH SP03. This update will automatically update to the Hazus-MH application once installed on your computer; however, in order for the SP 03 updates to automatically take place, SP01 and SP02 must be manually installed on your computer.
The following are the links to manually install the Service Packs to your machine:

Users can also call the FEMA Map Information Exchange (FMIX) at 1-877-336-2627 as an alternative means of support. The FMIX helps users during normal business hours to follow up on Help Desk tickets, receive assistance in using the Help Desk or obtain answer general questions about Hazus.
Regularly scheduled Hazus training classes are held at FEMA's Emergency Management Institute (EMI), located on the National Emergency Training Center campus in Emmitsburg, Maryland, 75 miles north of Washington, DC.
Courses provide instruction in all steps of the loss estimation process, from inventory verification and improvement to running a loss analysis; how to use Hazus results for mitigation, as well as for comprehensive planning, response and recovery activities; data management and useful GIS concepts. Emergency managers, GIS specialists, geologists, state and local planners, consultants and all those involved in risk assessment activities benefit from Hazus training. Please check the EMI course calendar for the schedule.
There are also a series of online training courses on Hazus available on the Esri website. Visit the Virtual Course page to view a list and description of these virtual courses.
HUGs provide opportunity for professionals to network and discuss their Hazus-related projects. There are HUGs in most states and many hold regularly scheduled conference calls to help their members connect, train and learn about the latest Hazus software development. More information about specific HUGs and how to join or even start your own, can be found on the Hazus User Groups web page.
