  2. What is HAZUS? • HAZUS is an add-on to ArcGIS to estimate physical, economic, and social impacts of disasters. It graphically illustrates the limits of identified high-risk locations due to natural disasters. • HAZUS is supported and promoted by FEMA for the purpose of providing communities with the means to identify risk from natural hazards. • Available from FEMA free of charge (requires ArcGIS license)

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

  4. What is a Hazard? • From our EOHS 572 course: • “a property or situation that in particular circumstances could lead to harm” (Royal Society, 1992) • A condition or situation which has the potential to create harm to people, property of the environment Royal Society, 1992. “Risk Analysis, Perception and Management.” The Royal Society, London.

  5. Supported Hazards • Hurricane Wind • Riverine and Coastal Floods • Earthquakes • Storm Surge (with most current version, combines flood and hurricane features)

  6. History • Program initiated in 1992 • Earthquake model first released in 1997 • Hurricane and Flood model development initiated in 1998 • Annual updates along with interim patches as required • Most recent version has Storm Surge option

  7. Loss Estimation Process • Identify physical landscape • Identify hazard • Consider what is at risk • Analyze social and economic impacts • Produce maps, tables, and reports

  8. HAZUS-MH: Models FLOOD HURRICANE EARTHQUAKE

  9. Background Inventory • HAZUS-provided inventory • General building types and occupancies • Lifelines • Replacement costs • Demographics • Hazard-specific • Specific building types • Elevation • Building configurations

  10. Integrating User-Provided Data • Non-Hazard Data Integration Tools • Comprehensive Data Management Systems (CDMS) enables integration of locally developed non-hazard data • CDMS validates that user data are compliant with HAZUS requirements • Hazard Data Integration • User-provided hazard maps (soils, elevation, liquefaction, etc.) can enhance the accuracy of loss estimations • Each model includes tools for integrating user-provided hazard maps

  17. Applications in Mitigation Planning & Emergency Management Emergency Preparedness Response & Recovery HAZUS-MH Loss Reduction (Mitigation)

  18. 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

  19. 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

  20. HAZUS Applications:Response and Recovery • Post-disaster damage assessment • Response planning for critical transportation outages • Identify critical infrastructure • Recovery action planning • Long-term economic recovery planning

  21. How Does HAZUS Support Emergency Management? • IDENTIFY vulnerable areas • ASSESS level of readiness and preparedness to deal with a disaster before disaster occurs • ESTIMATE potential losses from specific hazard events • 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)

  22. Who is HAZUS User? • HAZUS is used by a variety of communities and organizations across the United States: • Local and State Government • Federal Agencies • Educational Institutions • Private Industry • Others • Considerable international interest
