Transcript of "Donovan flackericmacneil"

  1. 1. Earthquakes Donovan Flack Eric MacNeil 3rd hour April 8, 2011
  2. 2. Basic Background Information <ul><li>What is an earthquake? </li></ul><ul><li>A series of vibrations induced in the earth’s crust by abrupt rupture. </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>By a Richter scale. </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>greatness of size or amount. </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>Using the Richter scale you can assign a number on the size of the earthquake by measuring it’s maximum amplitude of the seismic wave. </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>Buildings are destroyed. </li></ul><ul><li>People are killed </li></ul><ul><li>City’s are destroyed and a lot of cultural damage is done. </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 and S waves </li></ul><ul><li>What two types of body waves are there? </li></ul><ul><li>P and S </li></ul>
  5. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>They travel fast through rock material by making the rock to vibrate. </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>S waves travel by making the rock vibrate in right angles where the wave is moving. </li></ul><ul><li>Which move faster? </li></ul><ul><li>P-waves move faster then S-waves do. </li></ul>
  6. 6. Elastic Rebound <ul><li>The elastic rebound theory is an explanation for how energy is spread during earthquakes. </li></ul><ul><li>They occur at plate boundaries. </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>occurred near the northeast coast of Honshu. </li></ul><ul><li>This quake occurred </li></ul><ul><li>March 11, 2011 </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>The magnitude was 9.0 </li></ul>
  8. 8. Effects on the environment/earth <ul><li>The earthquake effected the earth’s mineral supplies </li></ul><ul><li>The earthquake effected the people who live there </li></ul><ul><li>The earthquake effected the economy of Japan. </li></ul>
  9. 9. Effects on the People of Japan <ul><li>Jobs are ruined </li></ul><ul><li>Everyone houses are destroyed. </li></ul><ul><li>Business are ruined </li></ul>
  10. 10. Effects on the Economy of Japan <ul><li>Japan will go in a depression. </li></ul><ul><li>Japan has to rebuild everything </li></ul><ul><li>Japan is in a economic disaster. </li></ul>
  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>A tsunami is a tidal wave </li></ul><ul><li>Tsunami waves are formed as the displaced water, which acts under the influence of gravity, attempts to find a stable position again. </li></ul><ul><li>Typically, the height of a tsunami wave is anywhere from 30-50 feet tall, sometimes reaching 100-300 hundred feet tall. </li></ul><ul><li>The speed at which tsunamis travel depends on the ocean depth. A tsunami can exceed 500 mph in 15,000 feet of water but slows to 40 feet or less in 100 feet of water. </li></ul>
