  1. GIS BASED SEISMIC DAMAGE ESTIMATION FOR THE CITY OF KELOWNA Md. Nurul Alam Graduate Student Supervisors: Dr. Solomon Tesfamariam and Dr. M. ShahriaAlam

  2. 6.4 Magnitude Quake Shakes Southwest B.C. Friday, September 09, 2011 at 12:41:34 PM ( Source : USGS)

  3. USGS PAGER - Prompt Assessment of Global Earthquakes for Response Report Green Alert

  4. Outline • Background • Methodology • Outcome • Conclusion & Future Directions

  5. Effects of Earthquake in Haiti, January 2010

  6. Effects of Earthquake in Chile, February 2010

  7. “Know Risk, No Risk” International Strategy for Disaster Reduction

  8. Seismic Damage Assessment for the City of Kelowna

  9. Objective • Development of a GIS-based Seismic Damage Assessment Tool with the help of RADIUS • Implement a Case Study for the City of Kelowna

  10. RADIUS Risk Assessment Tools for Diagnosis of Urban Areas against Seismic Disasters

  11. Proposed GIS based RADIUS Method Query GIS Modeling for Input Approved Data Collection Data Inventory Quality Inspection Engineering Analysis with RADIUS Generation of Seismic Damage Maps in GIS Not Approved

  12. Scenario Earthquake Selection Seismic Hazard Seismic Damage Estimation Soil Classification Data Inventory and Vulnerability GIS Platform Simplified RADIUS Methodology ( After Nippon Koi and Oyo 2001)

  13. What is GIS? Geographic Information System

  14. GIS Implementation Process Sources Analog2Digital Layering Output & Analysis Design & Linking

  15. Scenario Earthquake Selection Seismic Hazard Seismic Damage Estimation Soil Classification Data Inventory and Vulnerability

  16. Source: Natural Resources Canada

  17. Selection of Probable Seismic Event • Scenario 1: Mw = 6.5 underneath the City • Scenario 2: Mw = 7.3 in Cascadia Subduction Zone

  18. Scenario Earthquake Selection Seismic Hazard Seismic Damage Estimation Soil Classification Data Inventory and Vulnerability Simplified RADIUS Methodology

  19. Surface Ground Amplification for Different Soil/Rock types in RADIUS (After Nippon Koi and Oyo 2001)

  20. Soil Classification

  21. Scenario Earthquake Selection Seismic Hazard Seismic Damage Estimation Soil Classification Data Inventory and Vulnerability

  22. Data Sources • Secondary Data • City of Kelowna • Statistics Canada • USGS • Agriculture Canada • UBC Vancouver • Primary Data • Survey through Google maps

  23. Existing Database

  24. Compilation of Inventories in GIS

  25. Compilation of Inventories in GIS (continued)

  26. Study Area with 4km × 4km grids Basic Input for RADIUS

  27. Scenario Earthquake Selection Seismic Hazard Seismic Damage Estimation Soil Classification Data Inventory and Vulnerability Simplified RADIUS Methodology

  28. Mean damage factors (MDF) for major classes of buildings in Kelowna (After Onur et al. 2005)

  29. Casualty Coefficient After UNISDR 1999

  30. Probable Damage

  31. Scenario 1 : Mw = 6.5 underneath the City Distribution of Casualties ( Casualty Count :161) Distribution of Damaged Buildings (Count : 2374) Distribution of MMI

  32. Scenario 1 : Damage to lifelines

  33. Scenario 2 : Mw =7.3 in Cascadia Subduction Zone Distribution of Building Damage Distribution of Injuries Distribution of MMI

  36. Wildfire Risk Assessment

  37. Proposed Wild Fire Risk Assessment Methodology

  38. Wildfire Risk

  39. Selected Risky Areas A8, C2, C3, C8, D6, D7 and E7

  40. Priorities : C2>E7>A8>D7>D6 & C8>C3

  41. Future Fire Station Location Selection

  42. Contingency Planning

  43. Goal & Main Tasks of the project… Overall Goal: • To develop a comprehensive multi-hazard risk reduction “Contingency Planning” strategy that is linked to an easy implementation framework Main Tasks: • Task I: Determine status of existing contingency plans • Task II: Turn existing contingency plans into scenario-based contingency plans (using geo-hazard vulnerability map)

  44. Contingency Planning Framework Establish the Context in Relation to Potential Hazards Vulnerability Assessment & Loss Estimation • Scenario Development • (Scenario will be developed using RADIUS tool) • Low Risk • Moderate Risk • High Risk Develop Template for Contingency Plans to Address Needs and Suite Risk Scenarios Plan Development at City Level

  45. Review Mandates for Various Levels & Sectors Extended Roles and Responsibilities of agencies Compare with existing and Gap analysis Training & Capacity Building Urban planning solutions Pre-positioning of facilities Contingency Planning Framework Establish the Context in Relation to Potential Hazards Vulnerability Assessment & Loss Estimation Scenario Development • Low Risk, Moderate Risk, High Risk Develop Template for Contingency Plans to Address Needs and Suite Risk Scenarios Plan Development at Various Levels Perform Review & Revision After Major Events or as needed

  46. W h o , W h a t , W h e r e • Coordination and Support • Services • Disaster Management • Education • Food Security • Health / Health and Nutrition • Infrastructure • Livelihood Economic recovery • Protection • Shelter • Water Hygiene and Sanitation • Psycho social • Early Recovery
