1. REMEMBERING 2O10’S VOLCANIC ERUPTIONS Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA

2. 2010 THE YEAR OF “RECORD AND NEAR-RECORD” NATURAL DISASTERS

3. VOLCANOES are awesome manifestations of heat flowing as a result of hot spots (e.g., Hawaii and Iceland) and movement along faults located in subduction zones (e.g., the Pacific Rim).

4. PLANET EARTH HAS 1,500 “VOLCANO LABORATORIES” EACH VOLCANO HAS A UNIQUE ERUPTION HISTORY, WHICH CONTAINS VALUABLE LESSONS ON DISASTER RISK REDUCTION

5. GLOBAL DISTRIBUTION OF 1,500 ACTIVE VOLCANOES

6. 2010’S NOTABLE VOLCANIC ERUPTIONS ICELAND March 20 and April 14, 2010 INDONESIA October 25-27 – November 24, 2010

7. IMPACTED NATIONS Iceland (Europe) Indonesia

8. SOCIETAL IMPACTS DURING 2010 The volcanic ash cloud over Europe from Iceland’s Eyjafjallajökull volcano paralyzed air travel in Europe for weeks and cost the industry over $2 B. The eruption of Mount Merapi immediately after a M7.7 earthquake and a tsunami caused loss of life and a triple disaster in Indonesia.

9. INDONESIA A LAND OF ISLANDS AND SUBDUCTION ZONE VOLCANOES

10. INDONESIA HAS MORE THAN 17,000 ISLANDS

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

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. SUBDUCTION ZONE VOLCANOES

14. MOUNT MERAPI, INDONESIA, IS A SUBDUCTION ZONE VOLCANO Mount Merapi has a history of starting full scale erupt- ions with a pyroclastic cloud and flow.

17. ICELAND A LAND OF FIRE (HOT SPOT VOLCANOES) AND ICE

18. ICELAND’S VOLCANOES

19. Unlike the subduction zone volcanoes along the Pacific Rim where the slow rise of magma gives early seismic warnings that an eruption is imminent, Iceland's hot spot volcanoes tend to erupt under ice sheets with little warning.

20. Iceland lies on the Mid-Atlantic Ridge, the highly volatile divergent boundary between the Eurasian and North American tectonic plates that is marked by earthquakes and volcanic eruptions.

36. A dark and spectacular volcanic cloud spread over Britain and toward continental Europe on Thursday, April 15, forcing airlines to cancel thousands of flights as it drifted at high altitude south and east from the continuing eruption in Iceland.

37. ASH CLOUD FROM APRIL 14 ERUPTION

38. ICELAND’S AIR TRAFFIC DISRUPTED BY THE ASH

39. EUROPEAN AIR TRAFFIC DISRUPTED: APRIL 15, 2010

40. The ash cloud, made up of minute particles of silicate that can severely damage jet engines, left airplanes stranded on the tarmac at some of the world’s busiest airports.

41. APRIL 19: Eyjafjallajökull is still erupting.

42. MAP OF AIRPORTS CANCELLING FLIGHTS: APRIL 15, 2010

43. A week of airspace closures caused by the ash threat to planes created the worst breakdown in civil aviation in Europe since World War II, which caused more than 100,000 flights to be canceled and airlines to lose over $2 billion.

44. The Eyjafjallajökull Volcano: Lava and Lightning

53. A NEW THREAT: Scientists said the 800-meter fissure caused by the eruption was growing and heading towards the Myrdalsjokall glacier, which sits atop Iceland’s powerful Katla volcano

54. An eruption at the Katla volcano would likely be very disastrous for Iceland as well as for other nations.

55. ERUPTION OF MOUNT MERAPI EXACERBATED THE EARTHQUAKE-TSUNAMI DISASTER THAT OCCURRED ON OCTOER 25, 2010 October 25-27 – November 24, 2010

56. 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,

57. 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.

58. KNOWING THE ERUPTION HISTORY OF A VOLCANO IS A VITAL PART OF THE ART AND SCIENCE OF INTELLIGENT EVACUATION.

59. 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.

60. CASUALTIES: 538 ON OCT 26, BUT TOLL CONTINUED TO RISE 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.

61. MOUNT MERAPI ERUPTED THREE TIMES: OCT 26, 2010

62. THE RESPONSE TO A HUGE HUMANITARIAN NEED BEGINS The Indonesian government started by constructing 4000 shelter homes, while Aid workers were scrambling to provide tents, food, clothing, and medicine to evacuees while awaiting international assistance.

67. A LARGE ERUPTION: NOV 3

68. In consideration of the violence of the eruption on November 3 rd, the government widened the radius of the evacuation zone around Merapi from 5 to 10 km, and eventually to 12 km.

69. Aid workers say the conditions in the evacuee camps are very poor, with some shelters having as few as five lavatories for every thousand residents.

70. VERY VIOLENT ERUPTION ON NOV 5 Just before midnight, Merapi erupted with a 10 km ash plume that affected locations 250 km away and a pyroclastic cloud of ash and rock fragments that raced down the slopes at speeds of up to 100 km per hour.

74. NOV. 6 TH : A massive aid operation is underway to provide humanitarian assistance to some 200,000 people who fled the most violent eruptions in 100 years, especially on Thursday night (Nov 4 th ), which killed over 70 people.

75. Local government, the security forces, the Indonesian Red Cross, NGOs and hundreds of volunteers are distributing food, water and organizing basic medical care.

76. MERAPI’S ERUPTIONS CONTINUE : NOV 10

77. USA SENDS THREE VOLCANO EXPERTS WITH EXPERIENCE IN THE MAY 1980 ERUPTION OF MOUNT ST HELENS TO ASSIST INDONESIAN EXPERTS IN THEIR ASSESSMENTS OF MERAPI.

78. Merapi’s eruptions, which began on Oct. 26, passed the 120-hour mark on Nov. 11, eclipsing its old record set in 1872.

79. NEW HEALTH CARE PROBLEMS: HIGH SULFUR DIOXIDE : NOV 11

80. NOV 11: According to the National Disaster Management Agency, 194 deaths, 598 people are hospitalized, and 343,909 people have been evacuated to the safety zone, 12.4 miles (20 km) away from Merapi.

81. NEW THREAT-FLASH FLOODS: Volcanic debris has clogged many of the rivers (e.g., Code River) that begin on Merapi's slopes, and officials are now worried that cold lava could overwhelm these rivers and create conditions for flash floods.

82. ASH-COVERED SCHOOL: NOV 14

83. NOV 15 th Evacuees begin returning home to take care of livestock and to assess vitality of resuming their former livelihoods

84. AS OF NOV 16 th Merapi had emitted more than 140 million cubic meters of materials, higher than the 100 million cubic meters emitted in 1872 and the 14 million cubic meters emitted in 2006.

90. NOV 19 th The Government declared that it will end the emergency response period for the Mount Merapi volcanic eruption disaster on November 24 th

91. NOV 20 th Indonesia's Yogyakarta airport, which had been closed for about two weeks by the eruption of the Mount Merapi volcano, reopened for operations on Saturday, November 20.

92. After the end of the emergency response period, the National Disaster Management Agency (BNPB) will begin implementing the reconstruction and rehabilitation programs for Mount Merapi victims

93. The BNPB has at its disposal Rp397 billion to help disaster victims, with 80 percent allocated to meet the victims` physical needs and 20 percent allocated for operational expenses..

94. "Houses that have been damaged or destroyed will be rebuilt; people who have lost cattle will be financially compensated, and food will be provided for those who lost crops.

95. But there also was more than Rp3 trillion in stand-by funds to respond to the needs of reconstruction and rehabilitation

96. NOVEMBER 26-28: Indonesia’s Mount Bromo, also located on Java, began to erupt on Friday, eventually emitting ash clouds on Sunday that reached a height of up to 700 meters (2,300 feet). on Sunday.

97. POTENTIAL EVACUEES WATCH AS MOUNT BROMO ERUPTS: NOV 28

98. Those living in the vicinity of Mount Bromo remained on high alert as the East Java administration closed the airport and began to prepare nearby residents for the possibility of an urgent evacuation.
