Tsunami

  1. 1. <ul><li>What does the word Tsunami mean? </li></ul><ul><li>The term tsunami comes from the Japanese meaning harbour and wave . Tsunamis are common throughout Japanese history ; approximately 195 events in Japan have been recorded over the centuries. </li></ul><ul><li>It was called this because Tsunamis can suck all the water out of a harbour before the waves come back into shore. These waves may grow more than 100 feet tall and flatten whole villages. Hence its meaning. </li></ul>
  2. 2. <ul><li>What is a Tsunami? </li></ul><ul><li>A tsunami is a series of great sea waves caused by an underwater earthquake, landslide, or volcanic eruption. It is very rare but sometimes a tsunami can be generated by a giant meteor impact with the ocean </li></ul><ul><li>Try and imagine when you have tossed a pebble into a pond, then watched ripples spread out over the surface? Well a Tsunami works in much the same way. </li></ul>
  3. 3. <ul><li>What is a Tsunami? </li></ul><ul><li>These underwater earthquakes, landslides, or volcanic eruptions can generate a tsunami by creating a sufficient force and violent movement of the earth. This movement then causes a substantial and sudden displacement of a massive amount of water. </li></ul>
  4. 5. <ul><li>What is a Tsunami? </li></ul><ul><li>When the ocean is deep tsunamis can travel unnoticed on the surface at speeds up to 800 kms per hour, crossing the entire ocean in a day or less! A tsunami may be less than 30cm in height on the surface of the open ocean, which is why they are not noticed by sailors. </li></ul>
  5. 6. <ul><li>What is a Tsunami? </li></ul><ul><li>The powerful shock wave of energy travels rapidly through the ocean as fast as a commercial jet. Once a tsunami reaches shallow water near the coast it is slowed down. The top of the wave moves faster than the bottom, causing the sea to rise dramatically and wave to get allot bigger! </li></ul><ul><li>Tsunamis have been known to get as high as 30 meters, however most tsunamis cause the sea to rise no more than 9 meters. </li></ul>
  6. 7. What is the most devastating Tsunami on record? Show real life footage!
  7. 14. 2004 Tsunami <ul><li>The earthquake that generated the great Indian Ocean tsunami of 2004 is estimated to have released the energy of 23,000 Hiroshima-type atomic bombs, according to the U.S. Geological Survey (USGS). </li></ul>
  8. 16. 2004 Tsunami <ul><li>This Tsunami was caused by giant forces that had been building up deep in the Earth for hundreds of years. Then on December 26 they were released, suddenly shaking the ground violently and unleashing a series of killer waves that sped across the Indian Ocean at the speed of a jet airliner. </li></ul>
  9. 17. 2004 Tsunami <ul><li>By the end of the day more than 150,000 people were dead or missing and millions more were homeless in 11 countries, making it perhaps the most destructive tsunami in history. </li></ul>
