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 Texas Hazard Mitigation Package (THMP) Easy to Use (less expensive) Identification Tool www.THMP.info HAZUS Loss Estimation Tool Local Hydrology & Hydraulic Studies H & H specific applications H&H Engineering Tools & Data Highly Accurate (more expensive) HAZUS-MH: Family of Products 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 ArcGIS / ArcView & Spatial Analyst www.esri.com 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 Requirements From FEMA Web Site ArcGIS and HAZUS require significant computing power and resources (Computer hard disk space varies per dramatically per User) HAZUS-MH: Methodology 5.
