What is HAZUS-MH?
HAZUS-MH is a planning tool that estimates
damage and losses resulting from natural hazards
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 an empirical model based on observation and experiment

Models
HAZUS-MH is a multi-hazard (MH) application
Flood, Hurricane (Wind), Earthquake
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
Loss
Reduction
(Mitigation)
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
HAZUS Applications:
Mitigation
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:
Response and Recovery
Post-disaster damage assessment and ground-
truthing
Response planning for critical transportation
outages
Identify critical infrastructure
Recovery action planning
Long-term economic recovery planning
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)
