Transcript of "David+bellon"

  1. 1. Effects of Earthquakes David Bellon Mrs. Smith 5th hour April 8, 2011
  2. 2. About Earthquakes <ul><li>What is an earthquake? </li></ul><ul><li>Shaking that results from the movement of rock beneath Earth’s surface </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>A device that converts ground movements into a signal that is recorded and printed. This is called a seismograph </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>The measurement of the Earthquakes sttrenght based on seismic waves </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>The moment-magnitude scale measures magnitude </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>Can cause unstable objects to fall </li></ul><ul><li>Dramatic ground movements can cause landslides </li></ul><ul><li>Buildings can collapse </li></ul><ul><li>Undersea Earthquakes can send tsunamis onto the land. </li></ul>
  4. 4. Waves <ul><li>What are earthquake waves called? </li></ul><ul><li>Seismic waves </li></ul><ul><li>What two types of seismic waves are there? </li></ul><ul><li>P Waves, Primary Waves. </li></ul><ul><li>S Waves, Secondary Waves. </li></ul><ul><li>What two types of body waves are there? </li></ul><ul><li>When P and S Waves arrive at the surface, some of them turn into Surface Waves </li></ul>
  5. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>P Waves compress and expand and can travel through solids and liquids, these arrive at the surface first </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>S Waves vibrate side to side and up and down and can only travel through solids </li></ul><ul><li>Which move faster? </li></ul><ul><li>P Waves </li></ul>
  6. 6. Elastic Rebound <ul><li>States that Tectonic Plates move relative to each other </li></ul><ul><li>Transform Boundary </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>Friday March 11, 2011 5:46 P.M. </li></ul><ul><li>This quake occurred </li></ul><ul><li>Northeast of Honshu </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>9.0 </li></ul>
  8. 8. Effects on the environment/earth <ul><li>Japans coastline may have shifted 4 meters </li></ul><ul><li>Probably shifted the Earth’s axis by 6.5 inches </li></ul><ul><li>Made the day shorter by 1.8 millionth of a second </li></ul>
  9. 9. Effects on the People of Japan <ul><li>Many people died </li></ul><ul><li>There is a need for food and water </li></ul><ul><li>Need to find family </li></ul>
  10. 10. Effects on the Economy of Japan <ul><li>Type one effect here </li></ul><ul><li>Type one effect here </li></ul><ul><li>Type one effect here </li></ul>Replace these words with an appropriate image. Replace these words with an appropriate image. Replace these words with an appropriate image.
  11. 11. GPS Sensors <ul><li>One interesting fact about this earthquake is that it moved several GPS sensors. This will require …(Type answer here) </li></ul><ul><li>How does elastic rebound explain this movement? </li></ul><ul><li>Type your answer here . </li></ul>
  12. 12. Tsunamis <ul><li>What is a tsunami? </li></ul><ul><li>Type your answer here. You can erase the question. </li></ul><ul><li>How do tsunami waves appear at sea? </li></ul><ul><li>Type your answer here. You can erase the question. </li></ul><ul><li>How high can tsunami waves be? </li></ul><ul><li>Type your answer here. You can erase the question. </li></ul><ul><li>How fast can tsunami waves move? </li></ul><ul><li>Type your answer here. You can erase the question. </li></ul>
