3. THMP Map Viewers [ Internet Mapping ]
Intro to Map Viewers and the 3 “viewing/mapping” options: 1 Summary option (Hazard Summary), 2 Detail options (Weather & Non Weather).
Note: A variety of Base Map data is included in all 3 Viewers
THMP Map Viewers
[ Internet Mapping ]

4. SUMMARY DATA:
Number of hazard occurrences (frequency) over reported period of time,
summarized by county – and mapped into 4 classes (5 counting “0”)
Summary data is provided for 10 different hazards:
Hurricanes & Tropical Storms
Tornadoes
Floods
Other Storms
Drought
Outdoor Fires
Extreme Temperatures
Earthquakes
Hazardous Materials
Subsidence
For the 10 hazards, Weather and Non Weather are “combined” for the Summary Viewer

5. Hurricanes: 1851 - 2001 Map 1: Hurricanes:
Layer List shown w/ Data Layer visible (checkmark) and active (button on & highlighted)

6. Hurricanes & Tropical Storms 1851 - 2001
Hurricanes and Tropical Storms data layers shown at the same time.
This is a rare example of it being OK to overlay 2 hazards (but these are closely related).
Otherwise, it is typically not wise to do so – because the data will become obscured

7. Map 3:
Floods

8. Floods: 1961 – 1999 Map 3 ZOOM: Legend and Attribute Table Displayed
Ex. Blanco county selected; 13 Floods = Class 2 on map
Floods: 1961 – 1999

9. Other Storms 1955-2003: Identify = Travis County

10. DETAIL DATA:
Hazard occurrences by actual location of event (if available),
hazard risk zones, and other significant data used in identification
and quantification of hazard risk
Detail data is provided for the same 10 hazard categories,
separated into Weather-related and Non Weather-related:
Weather-related Hazards
Hurricanes & Tropical Storms
Tornadoes
Floods
Other Storms
Drought
Outdoor Fires
Extreme Temperatures
Non Weather-related Hazards
Earthquakes
Hazardous Materials
Subsidence
Reminder that Detail data and the corresponding Map Viewers break hazards data into Weather & Non Weather

11. BASE MAPS: Reference geography to overlay with hazards
Base maps are provided for 6 different categories:
Administrative Boundaries
Transportation
Hydrography
Landscape
Population
Weather-base data
Reminder that a variety of Base Map data is provided for all 3 Map Viewers, but the 2 Detail Map Viewers have substantially more.

There are so many “points” along the ocean-side coast, they appear as a solid red line,
…but they’re really like the inland-side red points.

34. THMP to HAZUS Provides a complex, desktop application (at a cost?) to:
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

35. 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)

36. 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 <
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
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

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

38. Emergency Preparedness
Develop emergency response plans
Temporary housing
Debris removal
Emergency power and water
Emergency medical services
Evacuation/emergency route clearance
Organize response exercises

39. 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

40. 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

41. HAZUS-MH: Digital Elevation Model & Stream Generation
Ex. Travis County being prepared for Hydrologic and Hydraulic analysis

42. 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

43. HAZUS-MH: Analysis Damage Assessment: (ex. Residential Buildings)
Number of Residential Buildings in each Census Block
(of Study Area) with 1 – 10% structural damage

44. Although damage was light (1-10%) for most residential buildings,
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

45. 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

46. 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

Instructor-led, Computer-based 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
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.
