  1. Part III: Tools for Risk AssessmentRADIUS Tool- Simple Damage Estimation Software - Dr. Carlos Villacis

  2. Software Purposes • To facilitate preliminary estimation of earthquake damage in developing countries • To be used by city administrators and general public, not for professional purposes • To assist in decision making • To raise awareness of earthquake risk

  3. Software Characteristics Goal: To make it as useful and accesible as possible • Widely available platform (runs on MS-Excel) • Simple, user-friendly • Help Function/User Instructions are included • Narrated Demonstration Video is included • NOT a GIS(Geographic Information System) type of program • A GIS Sample is added for comparison (GIS is a very useful risk-assessment tool)

  4. Input Data Program uses commonly available city information • Shape of target region (entered as a grid) • Population and its distribution • Building Inventory and its distribution • Ground Characteristics (Soil conditions) • Lifelines information • Choice of Scenario Earthquake and its parameters

  5. Output • Ground Shaking Distribution (PGA or MMI Intensity) • Building damage • Lifelines damage • Human Impact (number of deaths and injuries) • Summary Tables and Thematic Maps showing the results

  6. Example of Data Input Process • Shape of target region input as a grid Example for Kobe city

  7. Example of Data Input Process • Specify the City Area using Excel Mesh • Input Total Population and Building Counts

  8. Example of Data Input Process • Input Area ID and Area Name

  9. Example of Data Input Process Specify the Mesh Weight (building, population distribution)

  10. Example of Data Input Process • Input Mesh Weight to distribute the building and population count

  11. Example of Data Input Process • Specify Ground Characteristics (Soil conditions)

  12. Example of Data Input Process • Input Local Soil Characteristics

  13. Example of Data Input Process • Specify Building Inventory by Area • Percentage of 10 Building Classes in each Area

  14. Example of Data Input Process • Input Building Inventory by Area • Buildings and Population are distributed by Mesh Weight

  15. Example of Data Input Process • Specify and Enter Scenario Earthquake

  16. Output Examples • Building Damage Distribution

  17. Tool Applications • Understanding of cities’ earthquake risks • Estimation of impact of past well-known earthquakes • Estimation of impact of any number of possible future earthquakes • Delineation of planning policies by decision makers • Education and risk awareness of the public

  18. Incorporating DRM in Urban Planning Katmandú Tijuana Dehradun Antofagasta

  19. Working with local organizations Training to Kathmandu City officers Working session with Tijuana planners Public seminar in Antofagasta to discuss project findings

  20. Results 2007 2003 2012 2022

  21. CRÍTICO ALTA MEDIA BAJA LEVEL RISK- Antofagasta -Chile Developing solutions…

  22. Tangible Products Seismic scenarios Development plans Local Capacity Building

  23. Mitigation Option 1 Cost= $ Mitigation Option 2 Cost= $$$ Mitigation Option 3 Cost= $$ Mitigation Option 4 Cost= $$ 30% 60% 90% Risk Reduction Potential Tangible Products Mitigation Options

  24. Tangible Products Investing to reduce Tijuana’s risk Curve e = Investing $15 Mill. in 25 years

  25. END Thank you for your Attention.
