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
Local Hydrology & Hydraulic Studies www.THMP.info Texas Hazard Mitigation Package (THMP) Identification Tool HAZUS Loss Estimation Tool Local Hydrology & Hydraulic Studies H & H specific applications Engineering Tools & Data Easy to Use (less expensive) All 3 serve a different, yet related, purpose All 3 can be used together to accomplish objectives H & H 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 Project team: Sponsored by FEMA Management by the National Institute of Building Sciences Technical oversight by Committees for earthquake, wind, flood and software Technical development and testing by consultants User involvement throughout development

Applications in Mitigation Planning & Emergency Management Emergency Preparedness Response & Recovery 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
HAZUS-MH allows user to: 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)
