  1. VOLCANO SINABUNG ON NORTH SUMATRA, INDONESIA ERUPTSNovember 3, 2013 Walter Hays, Global Alliance for Disaster Reduction, Vienna, Virginia, USA 

  2. MOUNT SINABUNG: NOV. 3, 2013

  3. UNTIL AUGUST, 2010, SINABUNG HAD BEEN INACTIVE FOR 400 YEARS The August eruption led to an evacuation of 30,000 people

  4. SEPTEMBER 2013 ERUPTION • An eruption in September 2013 also prompted an evacuation--- about 3,500 villagers lining within 3 km of the volcano.

  5. 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.

  6. 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.

  7. INDONESIAN AUTHORITIES HAVE NOW INCREASED THE ALERT LEVEL

  8. UNDERSTANDING EXPLOSIVE VOLCANOES

  9. INDONESIA

  10. INDONESIA’S VOLCANOES

  11. VOLCANOES PART OF THE PACIFIC “RING OF FIRE,” INDONESIA HAS 127 ACTIVE VOLCANOES AS A RESULT OF COMPLEX SUBDUCTION OF THE INDO-AUSTRALIA AND EURASIATECTONIC PLATES

  12. 542 OF THE 1,500 ACTIVE VOLCANOES ARE LOCATED IN “RING OF FIRE”

  13. VOLCANO HAZARDS CAN HAVE FAR REACHING IMPACTS • VERTICAL PLUME (can affect jet aircraft) • ASH AND TEPHRA • LATERAL BLAST • PYROCLASTIC CLOUDS, BURSTS, AND FLOWS

  14. 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)

  15. CAUSES OF RISK LATERAL BLAST PYROCLASTIC FLOWS FLYING DEBRIS VOLCANIC ASH VOLCANIC ERUPTIONS LAVA FLOWS CASE HISTORIES LAHARS TOXIC GASES

  16. VOLCANO HAZARDS • PEOPLE & BLDGS. • VULNERABILITY • LOCATION • PREPAREDNESS • PROTECTION • EARLY WARNING • EMERGENCY RESPONSE • RECOVERY and • RECONSTRUCTION VOLCANO RISK POLICY OPTIONS ACCEPTABLE RISK RISK UNACCEPTABLE RISK GOAL: VOLCANO DISASTER RESILIENCE INDONESIA’S COMMUNITIES DATA BASES AND INFORMATION HAZARDS: GROUND SHAKING GROUND FAILURE SURFACE FAULTING TECTONIC DEFORMATION TSUNAMI RUN UP AFTERSHOCKS

  17. RISK ASSESSMENT • VULNERABILITY • EXPOSURE • EVENT • COST • BENEFIT VOLCANIC ERUPTIONS EXPECTED LOSS POLICY ADOPTION • CONSEQUENCES POLICY ASSESSMENT TOWARDS DISASTER RISK REDUCTION FOR VOLCANOES

  18. THE KEYS TO RESILIENCE: 1) KNOW THE ERUPTIVE HISTORY OF YOUR REGION’S VOLCANOES,2) BE PREPARED3) HAVE A WARNING SYSTEM 4) EVACUATE5) LEARN FROM THE EXPERIENCE AND START OVER

  19. MONITORING TECHNOLOGIES AND WARNING SYSTEMS ARE A VITAL PART OF BECOMING RESILIENT

  20. AIR AND LAND MONITORING TECHNOLOGIES ARE VITAL .
