may need further investigation
  • THMP
  • Provides easy-to-use, online application (free)
  • Identify historical hazard occurrences
  • actual hazard event locations
  • summarized by county
  • Identify hazard risk areas
  • Determine relative vulnerability (to population
    and property value)
  • Provides a complex, desktop application (at a
    cost?) to
  • Quantify the impact of a specified hazard event
  • Perform damage assessment and loss estimation
  • Study case may be identified in HAZUS,
    pre-determined by local experts and related
    information or by vulnerable areas previously
    determined in THMP

What is HAZUS-MH?
HAZUS-MH is a planning tool that estimates
damage and losses from natural hazards
  • 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
  • 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 Technical Components
  • Software Custom GIS (geographic information
  • 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 (MR1) runs on ArcGIS 9.x
  • Previous HAZUS-MH version runs on ArcGIS 8.x
  • 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

Applications in Mitigation Planning Emergency
Response Recovery
Emergency Preparedness
Loss Reduction (Mitigation)
Emergency Preparedness
  • Develop emergency response plans
  • Temporary housing
  • Debris removal
  • Emergency power and water
  • Emergency medical services
  • Evacuation/emergency route clearance
  • Organize response exercises

Loss Reduction (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

Response and Recovery
  • Post-disaster damage assessment and
  • Response planning for critical transportation
  • Identify critical infrastructure
  • Recovery action planning
  • Long-term economic recovery planning

Buildings) Mapped
Although damage was light (1-10) for most
residential buildings, many were impacted
particularly in one Census Block. The previous
THMP population vulnerability map indicated this
HAZUS-MH Analysis ex. General Building Stock /
Loss Estimate
Total economic loss can calculated for impacted
area or single Census Block The previously
identified Block totals 10,530,000 economic loss
HAZUS-MH Other Notes
  • Results can be viewed mapped many different
  • Including running mitigation scenarios to compare
  • 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

Training for Hazard Mitigation Emergency
Managers Professionals
  • Training Options
  • THMP
  • Texas Hazard Mitigation Package (THMP
    pronounced thump) is an online mapping system
    from TXGS for
  • displaying historical hazard occurrences,
    identifying relative risk areas and assessing
    vulnerabilities to population
  • and property. THMP is also a geographic data
    distribution tool for other mapping/GIS systems.
  • Course is designed to introduce all people to an
    easy-to-use, free application
  • HAZUS-MH is a custom GIS planning tool from FEMA
    used for damage assessment and loss estimation
    from real
  • or potential disasters Introductory and
    advanced courses focused on Flood and Hurricane
    modules (ArcGIS required)
  • Intro to GIS for THMP HAZUS Users
  • ArcGIS 9.0 is a geographic information system
    (GIS) from ESRI used for a multitude of
    applications, including
  • hazard mitigation and emergency response
  • Course is designed at an introductory level for
    THMP HAZUS Users

The Texas Geographic Society is pleased to
announce a new Training Program aimed at
professionals that need to more effectively
mitigate, manage and respond to hazards using
application-specific information and mapping
technology. The courses are intended to be free
or provided at a minimal cost.
2005 Schedule Texas GIS Forum (April) Texas
Hurricane Conference (May) Stay tuned for many
new training workshops held at hazard-related
venues (June Dec)
