Knowledge from hurricane disasters which occur annually in the Caribbean Sea, Gulf of Mexico and Western Pacific should be enough to make any nation susceptible to hurricanes adopt and implement policies that will facilitate disaster resilience. The people who know: 1) what to expect (e.g., storm surge, high-velocity winds, rain, flash floods, and landslides,), 2) where and when it will happen, and 3) what they should (and should not) do to prepare will survive. What is also needed is integration of scientific and technical solutions with political solutions for policies on preparedness, protection, early warning, emergency response, and recovery.

Two Hurricanes Approaching Hawaiian Islands 7-9 August 2014

  1. 1. TWO HURRICANES HEADED FOR HAWAII August 7, 2014
  2. 2. HURRICANES ISELLE (center) AND JULIO (right)
  3. 3. THEY ARE THE FIRST HURRICANES TO HIT HAWAII IN 22 YEARS Hurricane Iniki struck the island of Kauai on September 11, 1992 with peak intensity winds reaching 145 MPH
  4. 4. Hurricane Iniki Wind Damage 11 September 1992
  5. 5. FORECAST: ISELLE PREDICTED TO MAKE LANDFALL ON THURSDAY (7 August) JULIO WILL PASS PASSED BY THE ISLANDS TO THE NORTH ON SUNDAY (10 August)
  6. 6. FOR EXTRA MEASURE A Magnitude 4.5 EARTHQUAKE RATTLED THE BIG ISLAND AS THE HURRICANES APPROACHED ON 7th AUGUST
  7. 7. POTENTIAL DISASTER AGENTS AND RISK FROM HURRICANES
  8. 8. POTENTIAL DISASTER AGENTS (AKA HAZARDS) OF A HURRICANE • WIND FIELD [CAT 1 (55 mph) TO CAT 5+ (155 mph or greater)] • DEBRIS • STORM SURGE/FLOODS • HEAVY PRECIPITATION/FLOODS • LANDSLIDES (MUDFLOWS) • COSTAL EROSION
  9. 9. Debris Damage from Iniki
  10. 10. HAZARDS ELEMENTS OF WINDSTORM RISK EXPOSURE VULNERABILITY LOCATION RISK
  11. 11. HIGH POTENTIAL LOSS EXPOSURES IN A HURRICANE Entire communities; People, property, infra- structure, business enterprise, government centers, crops, wildlife, and natural resources.
  12. 12. A DISASTER CAN HAPPEN WHEN THE POTENTIAL DISASTER AGENTS OF A HURRICANE INTERACT WITH A COMMUNITY’S VULNERABLE ELEMENTS
  13. 13. WIND PENETRATING BUILDING ENVELOPE HURRICANE UPLIFT OF ROOF SYSTEM FLYING DEBRIS STORM SURGE IRREGULARITIES IN ELEVATION AND PLAN SITING PROBLEMS FLOODING AND LANDSLIDES CAUSES OF DAMAGE “DISASTER LABORATORIES”
  14. 14. A DISASTER is --- The set of failures that overwhelm the capability of a community to respond without external help when three continuums: 1) people, 2) community (i.e. a set of habitats, livelihoods, and social constructs), and 3) complex events (e.g. windstorms, floods) intersect at a point in space and time.
  15. 15. Disasters are caused by single- or multiple-event natural hazards that, (for various reasons), cause extreme levels of mortality, morbidity, homelessness, joblessness, economic losses, or environmental impacts.
  16. 16. THE REASONS ARE . . . When it does happen, the functions of the community’s buildings and infrastructure can be LOST.
  17. 17. THE REASONS ARE . . . The community is UN- PREPARED for what will likely happen, not to mention the low-probability of occurrence, high-probability of adverse consequences type of events.
  18. 18. THE REASONS ARE . . . • The community has NO DISASTER PLANNING SCENARIO or WARNING SYSTEM in place as a strategic framework for early threat identification and coordinated local, national, regional, and international countermeasures.
  19. 19. THE REASONS ARE . . . • The community LACKS THE CAPACITY TO RESPOND in a timely and effective manner to the full spectrum of expected and unexpected emergency situations.
  20. 20. THE REASONS ARE . . . • The community is INEFFICIENT during recovery and reconstruction because it HAS NOT LEARNED from either the current experience or the cumulative prior experiences.
  21. 21. THE ALTERNATIVE TO A HURRICANE DISASTER IS HURRICANE DISASTER RESILIENCE
  22. 22. CHILE’S COMMUNITIES DATA BASES AND INFORMATION HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS •WINDSTORM HAZARDS •PEOPLE & BLDGS. •VULNERABILITY •LOCATION WINDSTORM RISK RISK ACCEPTABLE RISK UNACCEPTABLE RISK GOAL: HURRICANE DISASTER RESILIENCE • PREPAREDNESS •PROTECTION •EARLY WARNING •EMERGENCY RESPONSE •RECOVERY and RECONSTRUCTION POLICY OPTIONS
  23. 23. TECHNOLOGIES FOR MONITORING, FORECASTING, WARNING, AND DISASTER SCENARIOS ARE VITAL FOR SURVIVAL IN A HURRICANE
