What is HAZUS-MH?
It is an estimation tool, NOT a deterministic tool
It is a planning tool, NOT an engineering tool Engineering-level data (i.e. Hydrology & Hydraulic studies) can be
input to increase accuracy, but results still produce planning-level estimations
It also assesses population needs related to emergency management
It also allows users to compare results from different study case scenarios, including mitigation actions
HAZUS-MH is a planning tool that estimates damage and losses resulting from natural hazards
HAZUS-MH is an empirical model based on observation and experiment

Data Integration Tools
• Inventory Collection And Survey Tool (InCAST)
• Building Import Tool (BIT)
• * Flood Information Tool (FIT)
Linkage to 3rd-party Models• Areal Locations of Hazardous Atmospheres (ALOHA)
• Flood Waves (FLDWAV)
HAZUS-MH: Technical Components
Software: Custom GIS (geographic information system)
Runs on ESRI products; ArcGIS and Spatial Analyst
• ESRI products must be acquired separately
Spatial Analyst required for Flood Model only
• HAZUS-MH is free from FEMA <www.fema.gov/hazus>
Current HAZUS-MH version (MR1) runs on ArcView 9.0
Data: National data sets
Inventory of assets (buildings, infrastructure, population/demographics, etc.)
• Users may modify data sets or model factors
• Users may add their own data
HAZUS-MH: Technical Notes
Operating System Requirements Windows XP SP1 Windows 2000 SP1 – SP4
GIS Requirements ArcGIS 9.0, SP1 Spatial Analyst extension (Flood Model
only)
HAZUS-MH: Technical RequirementsFrom FEMA Web Site
ArcGIS and HAZUS require significant computing power and resources
(Computer hard disk space varies per dramatically per User)

Response & Recovery
Loss Reduction
(Mitigation)
Emergency Preparedness
HAZUS Applications:Emergency Preparedness
Develop emergency response plans
• Temporary housing
• Debris removal
• Emergency power and water
• Emergency medical services
• Evacuation/emergency route clearance
Organize response exercises
Mitigation Assessment
• Identify ‘at-risk’ communities
Mitigation Measures
• Strengthen existing structures
• Strengthen window/door openings and siding
Mitigation Programs
• Adopt and enforce hazard-resistant building codes
• Land use planning
HAZUS Applications:Mitigation
Post-disaster damage assessment and ground-truthing
Response planning for critical transportation outages
Identify critical infrastructure
Recovery action planning
Long-term economic recovery planning
HAZUS Applications:Response and Recovery
Benefit Summary
HAZUS-MH allows user to:• IDENTIFY vulnerable areas that may require planning
considerations
• ASSESS level of readiness and preparedness to deal with a disaster before disaster occurs
• ESTIMATE potential losses from specific hazard events (before or after a disaster hits)
• DECIDE on how to allocate resources for most effective and efficient response and recovery
• PRIORITIZE mitigation measures that need to be implemented to reduce future losses (what if)
