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

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

Applications in Mitigation Planning & Emergency Management

HAZUS-MH

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)
