  1. STRATEGIES FOR BECOMING DISASTER RESILIENT DURING 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA 

  2. PART 3: MAKE THE MEGACITIES MORE DISASTER RESILIENT

  3. MEGACITIES FACE HUGE DISASTERS FROM … • EARTHQUAKES • FLOODS • SEVERE WINDSTORMS • LANDSLIDES • VOLCANIC ERUPTIONS • WILDFIRES • TSUNAMIS • DROUGHTS

  4. WHAT HISTORY TEACHES • CITIES AND MEGACITIES EXIST BY GEOLOGIC, HYDROLOGIC, AND ATMOSPHERIC CONSENT, WHICH CAN BE WITHDRAWN WITHOUT NOTICE.

  5. A DISASTER OCCURS WHEN THE MEGACITY’S PUBLIC POLICIES ALLOW IT TO BE … UN—PREPARED UN—PROTECTED UN--WARNED UN—ABLE TO RESPOND EFFECTIVELY UN (NON)—RESILIENT IN RECOVERY

  6. QUESTION • WHAT IS A MEGACITY AND WHAT VULNERABILITY REDUCTION MEASURES WILL MAKE IT LESS VULNERABLE TO THE POTENTIAL DISASTER AGENTS OF A NATURAL HAZARD?

  11. CAIRO IS A MEGACITY AT RISK FROM NATURAL HAZARDS

  12. ISTHANBUL IS A MEGACITY AT RISK FROM NATURAL HAZARDS

  13. ISTHANBUL: CAUSES OF VULNERABILITIES • SIZE • FRAGILITY OF EXISTING BUIDINGS/INFRASTRUCTURE • INADEQUATE PROTECTION MEASURES • CONSTRUCTION MATERIALS AND PRACTICES

  14. SAN FRANCISCO: DEPENDENT ON TRANSPORTATION • DAMAGE TO ONE SPAN OF THE BAY BRIDGE IN 1989 CHANGED THE LIVES OF MILLIONS AND DISRUPTED MANY BUSINESSES. • NO ONE KNOWS THE TRUE COST.

  17. NAT. HAZARDS • INVENTORY • VULNERABILITY • LOCATION • PREPAREDNESS • PRPTECTION • EARLY WARNING • EMERGENCY RESPONSE • RECOVERY • EDUCATIONAL SURGES RISK ASSESSMENT DISASTER RESILIENCE ACCEPTABLE RISK RISK UNACCEPTABLE RISK VULNERABILITY REDUCTON DATA BASES AND INFORMATION MEGACITY HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS

  18. QUESTION • CAN WE MAKE MEGACITIES MORE RESILIENT TO NATURAL HAZARDS?

  19. YES BUT, IT IS A TIME-, PEOPLE-,, AND STAPLE- DEPENDENT PROCESS!

  20. INTERLOCKING CONCEPTS ON MEGACITIES AND NATURAL HAZARDS • NATURAL HAZARDS, GENERATE POTENTIAL DISASTER AGENTS WHICH CREATE RISK TO THE BUILT ENVIRONMENT. • THE CHOICE: LIVE WITH UNACCEPTABLE RISK OR ACCEPTABLE LEVELS OF RISK.

  21. INTERLOCKING CONCEPTS ON MEGACITIES AND NATURAL HAZARDS • UNACCEPTABLE RISK CALLS FOR PUBLIC POLICIES TO REDUCE VULNER-ABILITIES.

  22. INTERLOCKING CONCEPTS ON MEGACITIES AND NATURAL HAZARDS • VULNERABILITIES REFLECT POLICY FLAWS WITH RESPECT TO PREPAREDNESS, PROTECTION, EARLY WARNING, EMERGENCY RESPONSE, AND RECOVERY

  23. INTERLOCKING CONCEPTS ON MEGACITIES AND NATURAL HAZARDS • PREPAREDNESS, PROTECTION, RESPONSE, AND RECOVERY ARE THE MOST EFFECTIVE MEASURES. • BUT, THEY ARE HARD TO SELL TO THE PUBLIC AND TAKE TIME TO IMPLEMENT.

  24. POLITICAL SOLUTIONS CA MEGACITY DISASTER RESILIENCE WHAT’S NEEDED: A COMMON AGENDA (CA) OF TECHNICAL AND POLITICAL SOLUTIONS TECHNICAL SOLUTIONS

  25. POLITICAL SOLUTIONS CA STAPLE FACTORS S P O T THE EFFECTIVE SOLUTION FOR GREATER DISASTER RESILIENCE FACT: BUILD ON EACH MEGACITY’S UNIQUE STAPLE FACTORS TECHNICAL SOLUTIONS
