  2. Asian Tsunami: December 26th 2004 • Largest Earthquake in the World in 40 years • It is the fourth largest earthquake recorded since seismographic recording in 1900. • Major Tsunami engulfs coasts around the Indian Ocean • Probably the largest and most widespread disaster in modern history • Requires and is getting (with your help) the Greatest Disaster response in World History

  3. Totals of fatalities for each country 10 749 59 150 2 5 313 29 854 68 1 173 981 82 10 3 5 554

  4. Statistics • 12 countries around Indian Ocean affected • First estimates on 26/12/04: 15,000 dead • By 28/12/04 estimated over 50,000deaths • 29/12/04 estimated numbers reach 70,000 by later in the day this figure was 80,000 • UN estimates 5 million survivors are lacking food, shelter and clean water. • 30/12/04 estimated fatality figures now 120,000 (of which 80,000 thought to be in Indonesia) • 31/12/04 Indonesian government announce they have stopped counting the number of fatalities.

  5. The first views of the Tsunami:

  6. Afriyanti - has lost everyone in her family and all of her school friends.

  7. A Thai soldier cradles a western child - almost half the disaster's victims in Thailand are thought to have been holidaying foreigners.

  8. Many children – foreign and local – have lost parents

  9. The power of tsunamis only becomes clear as they approach shallow water along the coast

  10. But from the beaches few people recognised the danger of the white line on the horizon

  11. Their full force is unleashed as they break on to land

  12. Sundar Raj, 21, fisherman I was sleeping in our boat when the sea began making a rumbling sound. I saw the water level rising. I jumped into the water and tied my boat to the wharf as the waves began lashing me from behind. I climbed on to the jetty and ran.

  13. Whole villages were flattened as here in Sri Lanka

  14. Fishing boats, which provide essential food supplies for local people here in India, have been washed ashore

  15. Low lying areas have been left flooded with seawater which quickly becomes contaminated with sewage and dead bodies Male in the Maldives Banda Aceh in Sumatra, Indonesia

  16. Millions of people have been left homeless Cuddalore, south of Madras, India Penang, Malaysia

  17. A family survey what is left of their home south of Colombo, Sri Lanka

  18. Freeze Frame - Tsunami swallows the Chedi resort beach restaurant in Phuket.

  21. Early reports gave no hint of the scale of the disaster……. The Aftermath “Thousands are reported to have been killed, but there has been little news from the worst-hit areas where all transport and communication links were destroyed. “ bbc.co.uk 27.12.04

  22. Low lying coastal areas were left obliterated and flooded as here in Aceh province in Sumatra, Indonesia Current reports indicate that the north and west coasts of Sumatra have experienced the worst destruction

  23. Whole villages were flattened as here in Sri Lanka

  24. Fishing boats, which provide essential food supplies for local people here in India, have been washed ashore

  25. Scenes which were repeated across the Indian Ocean Sri Lanka Phuket, Thailand

  26. Why it happened

  27. Subduction zone where the Indian dives under the Eurasian Plate

  28. Tsunamis are created when: • Seafloor quickly changes shape • Water is displaced • Waves are formed as the displaced water mass, which is affected gravity, tries to move back

  29. Two tectonic plates, the Australian and Eurasian plates, meet just off Sumatra's south-west coast, grinding together and sending periodic seismic tremors through the region. At 0059 GMT a violent rupture occurred on the sea floor along a fault about 1,000km long.

  30. Tectonic Facts • The earthquake came just three days after a magnitude 8.1 earthquake in an uninhabited region west of New Zealand • Possible connection between these two earthquakes • Possibility of a seismic chain reaction across neighboring plates has also been considered • Total energy released by a magnitude 9.0 earthquake exceeds the total amount of energy consumed in the U.S. in one month • Massive release of energy and shift in mass insignificantly altered the Earth's rotation

  31. The USGS (United States Geological Survey) record of the earthquake

  32. The seismograph recording of the earthquake
