B. Asset Vulnerability:
Vulnerability = Exposure / Hazard Risk Zone
Vulnerable areas are displayed and classified by census geography
(Block or Census Tract) where Hazard Risk Zones intersect
Exposed Assets (Population, Property Value)
Hazard Risk Zone
Exposure
(ex. Population)
THMP Data Layers:

THMP to HAZUS
 THMP
Provides easy-to-use, online application (free) to:
 Identify historical hazard occurrences
• actual hazard event locations
• summarized by county
 Identify hazard risk areas
 Determine relative vulnerability (to population and property value)
 HAZUS
Provides a complex, desktop application (at a cost?) to:
 Quantify the impact of a specified hazard event
• Perform damage assessment and loss estimation analysis
…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
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: 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 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

(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 groundtruthing
 Response planning for critical transportation
outages
 Identify critical infrastructure
 Recovery action planning
 Long-term economic recovery planning
HAZUS-MH:
Digital Elevation Model & Stream Generation
Ex. Travis County being prepared for Hydrologic and Hydraulic analysis
HAZUS-MH: Compute Hydrology & Hydraulics
Flood area polygon (100-yr return) & Flood depth grid
for selected stream
This is our Study Case; same area identified in THMP
HAZUS-MH: Analysis
Damage Assessment: (ex. Residential Buildings)
Number of Residential Buildings in each Census Block
(of Study Area) with 1 – 10% structural damage
HAZUS-MH:
Damage Assessment: (ex. Residential 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 potential
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 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

Professionals
Training
Options:
 THMP [www.thmp.info]
 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
 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.
