Presentation Transcript

  1. Temperatures in the mountainous Tibetan plateau 5 km above sea level can reach minus six degrees at night, so the government quickly arranged to send five thousand tents and fifty thousand blankets for the homeless survivors.

  2. The government allocated $30 million for relief and mobilized more than 5,000 soldiers,medical workers and other rescue workers to join with 700 troops already on the ground.

  3. TAIWAN: APRIL 26, 2010

  4. M6.5 EARTHQUAKE AND 3- DAYS OF RAIN CREATE CONDITIONS FOR LANDSLIDES APRIL 26, 2010

  5. LANDSLIDE

  6. LANDSLIDE

  7. SEARCH AND RESCUE

  8. INDONESIA’S TRIPLE DISASTER STARTED WITH EARTHQUAKE AND TSUNAMI ON OCTOER 25, 2010 October 25-27 – November 24, 2010

  9. A M7.7 EARTHQUAKE, A 3 M-TSUNAMI-WAVE RUN UP, AND A LONG ERUPTION OF MOUNT MERAPI CAUSED LOSSES IN THE TENS OF MILLIONS, DISPLACED OVER 340,000, KILLING NEARLY 1,000 , AND POTENTIALLY AFFECTING THE HEALTH AND QUALITY OF LIFE FOR THOUSANDS,

  10. INDONESIA HAS MORE THAN 17,000 ISLANDS

  11. Sandwiched between two active earthquake belts, the Pacific “Ring of fire,” and the Alpide Belt, Indonesia experiences some of the most powerful earthquakes and volcanic eruptions on Earth.

  12. Indonesia is home to 129 active volcanoes, with the two most active ones — Mount Kelut and Mount Merapi — located on the island of Java, which also contains the Indonesian capital of Jakarta, roughly 500 km (300 mi) northwest of them.

  13. INDONESIA’S 129 ACTVE VOLCANOES(MOUNT MERAPI IS BOTTOM LEFT CENTER)

  14. Monday and Tuesday: Oct 25-26 Indonesia endured two days of environmental extremes after a powerful earthquake, a tsunami, and a volcanic eruption struck the Java region of the Indonesian archipelago.

  15. CASUALTIES: 538 ON OCT 26, BUT TOLL LIKELY TO RISE IN THE FUTURE The earthquake and tsunami run up left at least 500 dead, and the initial volcanic eruption left 38 dead, BUT, health impacts associated with Mount Merapi’s continuing eruption may have long-term impacts.

  16. THE M7.7 EARTHQUAKEEarly response was hindered by twenty-two aftershocks ranging from M5- 6.2

  17. TECTONICS OF THE REGION • The Australian and Eurasian plates meet in Indonesia, creating a tectonic setting favorable for generating earthquakes, tsunamis, and volcanic eruptions.

  18. TECTONICS OF THE REGION (Continued) • The Australian plate is moving northward and being subducted under the Eurasian plate in a zone marked by a submarine trench that can be traced from the northern tip of Sumatra to the Lesser Islands.

  19. SUBDUCTION ZONE

  20. SEISMICITY MARKS THE PLATE BOUNDARIES

  21. THE TSUNAMIRESPONSE WAS EXACERBATED BY REMOTENESS OF THE ISLANDS

  22. INDONESIA: LOCATION OF HISTORICAL TSUNAMIS

  23. The M7.7 earthquake generated a near-source tsunami with 3 m (10 ft) waves that struck within 5 minutes after the quake---so quickly that the regional tsunami warning system that was improved after the December 26, 2004 tsunami disaster, was ineffective..

  24. The tsunami, triggered by the 7.7-magnitude undersea quake, hit the Mentawai Islands late Monday, leaving thousands homeless, killing at least 500 people, and sweeping hundreds out to sea.

  25. TSUNAMI WAVE RUN UP IN MENTAWAI ISLAND

  26. MENTAWAI ISLAND: MANY SWEPT OUT TO SEA

  27. SEARCH AND RESCUE HINDERED BY POOR COMMUNICATIONS

  28. KNOWING WHERE, WHEN, AND WHY A TSUNAMI OCCURS IS A VITAL PART OF THE ART AND SCIENCE OF INTELLIGENT RISK REDUCTION.

  29. Tsunamis Are Associated with Subduction Zone Earthquakes • M7 or larger earthquakes that occur in oceanic subduction zones can cause: • Tsunamis

  30. A TSUNAMI WAVE CAN REACH 10 M OR MORE IN HEIGHT

  31. TSUNAMI HAZARDS (AKA POTENTIAL DISASTER AGENTS) • HIGH-VELOCITY, LONG-PERIOD WATER WAVES • WAVE RUNUP • FLOODING • WAVE RETREAT • SHORELINE EROSION

  32. CAUSES OF DAMAGE HIGH VELOCITY IMPACT OF INCOMING WAVES INLAND DISTANCE OF WAVE RUNUP VERTICAL HEIGHT OF WAVE RUNUP INADEQUATE RESISTANCE OF BUILDINGS TSUNAMIS FLOODING “DISASTER LABORATORIES” INADEQUATE HORIZONTAL AND VERTICAL EVACUATION PROXIMITY TO SOURCE OF TSUNAMI

  33. THE ART AND SCIENCE OF KNOWING WHEN TO EVACUATE BEFORE A TSUNAMI WAVE ARRIVES AND WHERE TO GO CAN BE THE DIFFERENCE BETWEEN LIFE AND DEATH.

  34. YOU CAN’T OUTRUN OR DIVERT10-M-HIGH, DEBRIS-LADEN, OCEAN WAVES THAT ARRIVE WITH A HIGH VELOCITY (E.G., 30 TO 300 KM/HR) AND MOVE INLAND FOR 2-3 KM, OR MORE

  35. M6.5 EARTHQUAKE STRIKES SOUTHEASTERN IRAN DECEMBER 21, 2010

  36. The M6.5 earthquake, centered near the location of the 2003 Bam quake in southeastern Iran, killed at least 11, damaged 1,800 homes, downed phone lines, and triggered landslides.

  37. Almost exactly seven years ago in the same region, a M6.6 earthquake struck the nearby city of Bam, killing more than 25,000 people and destroying a medieval castle that was one of Iran's most treasured archaeological sites.

  38. M7.2 EARTHQUAKE STRIKES VANUATU TSUNAMI WARNING ISSUED, THEN WITHDRAWN DECEMBER 25, 2010

  39. VANUATU
