  • 1. 542 OF THE 1,500 ACTIVE VOLCANOES ARE LOCATED IN “RING OF FIRE”
  • 2. REMEMBERING SOME OF THE LESSONS FROM ONE OF 2013’S NONDISASTERS PART 5: EXPLOSIVE VOLCANIC ERUPTIONS
  • 3. INDONESIA
  • 4. VOLCANO SINABUNG ON NORTH SUMATRA, INDONESIA ERUPTS November 3, 2013 --- But No Disaster This Time
  • 5. UNDERSTANDING EXPLOSIVE VOLCANOES
  • 6. 542 OF THE 1,500 ACTIVE VOLCANOES ARE LOCATED IN “RING OF FIRE”
  • 7. VOLCANOES IN INDONESIA INDONESIA, A PART OF THE PACIFIC “RING OF FIRE,” HAS 127 ACTIVE VOLCANOES AS A RESULT OF COMPLEX SUBDUCTION OF THE INDO-AUSTRALIA AND EURASIA TECTONIC PLATES
  • 8. INDONESIA’S VOLCANOES
  • 9. PHYSICAL EFFECTS OF EXPLOSIVE VOLCANIC ERUPTIONSA NATURAL HAZARD VERTICAL ASH PLUME, HIGH-VELOCITY LATERAL BLAST, TEPHRA, LAVA FLOWS, LAHARS, AND VOLCANIC WINTER
  • 10. VOLCANO HAZARDS CAN HAVE FAR REACHING IMPACTS • VERTICAL ASH PLUME (can affect jet aircraft) • ASH AND TEPHRA • LATERAL BLAST • PYROCLASTIC CLOUDS, BURSTS, AND FLOWS
  • 11. VOLCANO HAZARDS CAN HAVE FAR REACHING IMPACTS • LAVA FLOWS • LAHARS (can bury villages) • EARTHQUAKES (related to movement of lava) • “VOLCANIC WINTER” (causing famine and mass extinctions)
  • 12. CAUSES OF RISK LATERAL BLAST PYROCLASTIC FLOWS FLYING DEBRIS EXPLOSIVE VOLCANIC ERUPTIONS CASE HISTORIES VOLCANIC ASH LAVA FLOWS LAHARS TOXIC GASES
  • 13. BEFORE AUGUST, 2010, SINABUNG HAD BEEN INACTIVE FOR 400 YEARS The August eruption led to an evacuation of 30,000 people
  • 14. MOUNT SINABUNG: NOV. 3, 2013
  • 15. SEPTEMBER 2013 ERUPTION • An eruption in September 2013 also prompted an evacuation--about 3,500 villagers lining within 3 km of the volcano.
  • 16. OCTOBER 2013 ERUPTION • Another eruption on October 24th also prompted an evacuation of about 3,500 villagers lining within 2-3 km of the volcano.
  • 17. WHAT HAPPENED NOVEMBER 3RD • The 8,530-foot-high mountain erupted early on Sunday, November 3rd, sending a vertical ash plume 7,000 feet into the air. • This eruption prompted an evacuation of 1,500 people living within 3 km of the volcano.
  • 18. TOWARDS VOLCANIC ERUPTION DISASTER RESILIENCE
  • 19. VOLCANO RISK •VOLCANO HAZARDS •PEOPLE & BLDGS. •VULNERABILITY •LOCATION DATA BASES AND INFORMATION ACCEPTABLE RISK RISK UNACCEPTABLE RISK INDONESIA’S GOAL: VOLCANO DISASTER RESILIENCE COMMUNITIES POLICY OPTIONS HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS • PREPAREDNESS •PROTECTION •EARLY WARNING •EMERGENCY RESPONSE •RECOVERY and RECONSTRUCTION
  • 20. TOWARDS DISASTER RISK REDUCTION FOR VOLCANOES RISK ASSESSMENT • VULNERABILITY • COST • EXPOSURE VOLCANIC ERUPTIONS • EVENT EXPECTED LOSS • BENEFIT •CONSEQUENCES POLICY ASSESSMENT POLICY ADOPTION
  • 21. THE KEYS TO RESILIENCE: 1) KNOW THE ERUPTIVE HISTORY OF YOUR REGION’S VOLCANOES, 2) BE PREPARED 3) HAVE A WARNING SYSTEM 4) EVACUATE 5) LEARN FROM THE EXPERIENCE AND BE READY TO START OVER
  • 22. CREATING TURNING POINTS FOR FLOOD DISASTER RESILIENCE  USING EDUCATIONAL SURGES CONTAINING THE PAST AND PRESENT LESSONS TO FOSTER AND ACCELERATE THE CREATION OF TURNING POINTS
  • 23. 2014--2020 IS A GOOD TIME FOR A GLOBAL SURGE IN EDUCATIONAL, TECHNICAL, HEALTH CARE, AND POLITICAL CAPACITY BUILDING IN ALL FIVE PILLARS OF COMMUNITY DISASTER RESILIENCE
  • 24. CREATING TURNING POINTS FOR FLOOD DISASTER RESILIENCE INTEGRATION OF SCIENTIFIC AND TECHNICAL SOLUTIONS WITH POLITICAL SOLUTIONS FOR POLICIES ON PREPAREDNESS, PROTECTION, EARLY WARNING, EMERGENCY RESPONSE, AND RECOVERY
  • 25. INTEGRATION OF TECHNICAL AND POLITICAL CONSIDERATIONS OPPORTUNITIES FOR TURNING POINTS: For Disaster Resilience on local, regional, national, and global scales THE KNOWLEDGE BASE Real and Near- Real Time Monitoring Hazard, Vulnerability and Risk Characterization Best Practices for Mitigation Adaptation and Monitoring Situation Data Bases APPLICATIONS EDUCATIONAL SURGES Relocation/Rerouting of Cities and City Lifelines Enlighten Communities on Their Risks Create a Hazard Zonation Map as a Policy Tool Implement Modern Codes and Lifeline Standards Cause & Effect Relationships Introduce New Technologies Anticipatory Actions for all Events and Situations Move Towards A Disaster Intelligent Community Interfaces with all Real- and Near Real-Time Sources Gateways to a Deeper Understanding Build Strategic Equity Through Disaster Scenarios Involve Partners in Turning Point Experimemts Multiply Capability by International Twinning Update Knowledge Bases After Each Disaster
