HAZUS-MH: FEMA’S SOFTWARE PROGRAM FOR ESTIMATING POTENTIAL LOSSES FROM DISASTERS


EarthquakesEarthquakes


FloodingFlooding


HurricanesHurricanes


How can we plan to minimize damage and loss of life to prevent natural hazards from becoming natural

disasters?

HAZUS – a planning applicationHAZUS – a planning application


It is a planning tool, NOT an engineering tool Engineering-level data (i.e. Hydrology & Hydraulic studies for Flood

modeling) can be input to increase accuracy, but results still produce planning-level estimations

It estimates physical damage & economic losses

It assesses population needs related to emergency management

It allows users to compare results from different study case scenarios, including those that result from specific mitigation actions (useful for benefits analysis)

HAZUS-MH is a planning tool that estimates damage and losses from natural hazards

What Is HAZUS-MHWhat Is HAZUS-MH


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

Current HAZUS-MH version (MR3) runs on ArcGIS 9.2

Previous HAZUS-MH version (MR2) runs on ArcGIS 9.1

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

Technical ComponentsTechnical Components


Results can be viewed & mapped many different ways• Including running mitigation scenarios to compare results

Inventory includes many different classifications of general building stock (by occupancy, by building type), essential facilities (several types), transportation systems (several types), demographics and more…

Local data and more sophisticated HAZUS techniques enhance the analysis

State Mitigation PlanState Mitigation Plan

The Florida Hazard Mitigation Plan provides a framework for linking pre- and post-disaster mitigation planning and measures with public and private interests to ensure an integrated, comprehensive approach to disaster loss reduction.

HAZUS used extensively for review and analysis of hazards and risks.

Florida Catastrophic Planning ProjectFlorida Catastrophic Planning Project

The Florida Catastrophic Planning Project considers two catastrophic events: a breach of the Herbert Hoover Dike around the waters of Lake Okeechobee and a Category 5 hurricane making landfall in South Florida, which has a population of nearly seven million.

Additional use of HAZUS Building Stock DataAdditional use of HAZUS Building Stock Data

Debris calculations were performed using the Dewberry Disaster Assistance Response and Recovery Technology (DARRT) for Lee and Palm Beach Counties and a modified United States Army Corps of Engineers debris model for all others.

Except where the DARRT model was used, all building stock data on which estimates are based is from the HAZUS regional database.


Impact on Major Highway BridgesImpact on Major Highway Bridges

Impacts on bridges were modeled in HAZUS using SLOSH outputs from the National Hurricane Center

Why use SLOSH?Why use SLOSH?

Use the existing partnership with NOAA…FEMA doesn’t have surge modeling expertise

SLOSH is simplified and independently valid to within 20% of observed surge heights

Using SLOSH MOMs, the US is covered! FEMA already pays for SLOSH basin updates,

why pay for separate model development? Thousands of hurricane scenarios already

run, just need to do damage estimates
