HAZUS-MH Standard for Multihazard Risk Assessment on the National Stage
FEMA and Local Governments Battle Hazards With a New GIS Tool
Nationwide, the recognition of hazard vulnerability is growing. As a result, planners are reevaluating their communities' exposure to risks and considering proactive hazard mitigation measures. Such planning was given a boost in October 2000 when the Disaster Mitigation Act (DMA) was signed into law.
DMA 2000 encourages and rewards predisaster planning, calling for increased coordination between state and local governments. Interim final regulations published in February 2002 require communities to complete mitigation plans in order to receive hazard mitigation funds.
Often the greatest challenge in developing such plans is their scope. Reaching an understanding of how to prepare for, mitigate, respond to, and recover from hazards is a complicated journey. And as all aspects of hazard planning are interrelated, data compilation, evaluation, maintenance, and standardization create an imposing hurdle.
Comprehensive community planning relies on understanding risks to the physical, social, and economic components of a community. Only communities that understand their vulnerability to natural hazards can make informed decisions.
The Federal Emergency Management Agency (FEMA) latest risk assessment and loss estimation software package, HAZUS-MH (Multi-Hazard), can help answer complex hazard planning questions. By using their existing GIS in conjunction with HAZUS-MH tools, planners can integrate and analyze earthquake, hurricane wind, and flood information.
HAZUS-MH maps and displays hazard data, facilitating real-time support for natural disaster response and recovery as well as economic loss estimates for buildings and infrastructure. While a previous version of this software was made available in 1999, the upgraded HAZUS-MH provides emergency managers with new loss estimation tools for hurricane wind and flooding while taking advantage of the ArcGIS software platform.
A free software package, HAZUS-MH helps states, communities, and businesses prepare for, mitigate, respond to, and recover from hazardous events. To provide estimates of hazard-related damage before a disaster occurs, the software takes into account:
Unique Features of HAZUS-MH
HAZUS-MH can quantify the risk for a study area of any size, whether for a region, state, community, or neighborhood. Using ArcGIS technology, HAZUS-MH combines hazard layers with national databases, then applies standardized loss estimation and risk assessment methodology. The GIS environment allows users to create graphic presentations, helping communities visualize and understand their hazard risks and solutions.
Nationwide databases built into HAZUS-MH include data sets on demographics, building stock, essential facilities, transportation, utilities, and facilities with a high potential for loss. The software can estimate losses from earthquakes, hurricane winds, and floods. Updated hazard models supplement these new features:
Third party hazard models that address hazardous material releases and dam breaks are also accessible with HAZUS-MH.
By providing this software free of charge, FEMA hopes to facilitate effective hazard mitigation. Anticipating the scope of disaster-related damage and identifying areas of special concern can help protect the lives and livelihood of a community.
