Transcript of "Lyricandbrooke"

  1. 1. Earthquakes! Brooke Brown Lyric Estrada Mrs. Smith 3rd Hour April 8, 2011
  2. 2. Basic Background Information <ul><li>What is an earthquake? </li></ul><ul><li>The Shaking that results from the movement of rock beneath earth’s surface. </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>Seismograph </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>The measurement of an earth quakes strength based based on seismic waves and movement along faults. </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>Mercalli scale, and richter scale. </li></ul>
  3. 3. Waves <ul><li>What are earthquake waves called? </li></ul><ul><li>Seismic waves, P waves, S waves, surface waves. </li></ul><ul><li>What two types of seismic waves are there? </li></ul><ul><li>P waves (Primary), S waves (Secondary). </li></ul><ul><li>What two types of body waves are there? </li></ul><ul><li>Body and surface waves. </li></ul>
  4. 4. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>P waves travel through the body of the earth. </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>S waves travel only through solids. </li></ul><ul><li>Which move faster? </li></ul><ul><li>P waves travel faster than S waves. </li></ul>
  5. 5. Elastic Rebound <ul><li>Elastic Rebound, is a theory which attributes faulting to stresses. </li></ul><ul><li>Elastic rebound occurs in the transform boundary. </li></ul>
  6. 6. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>March 11. At 2:46. </li></ul><ul><li>This quake occurred </li></ul><ul><li>Japan. </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>9.0 magnitude. </li></ul>
  7. 7. Effects on the People of Japan <ul><li>Thousands of people are confirmed dead, injured or missing. </li></ul><ul><li>Towns in the country’s northeast coast were literally wiped out. </li></ul><ul><li>Countless people are seeking shelter. </li></ul>
  8. 8. GPS Sensors <ul><li>All the GPS’s will have to be reset. </li></ul><ul><li>How does elastic rebound explain this movement. </li></ul><ul><li>As plates on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their intial strength is exceeded. </li></ul>
  9. 9. Tsunamis <ul><li>What is a tsunami? </li></ul><ul><li>A giant wave caused by an earthquake on the ocean floor. </li></ul><ul><li>How do tsunami waves appear at sea? </li></ul><ul><li>3 or 4 foot waves. </li></ul><ul><li>How high can tsunami waves be? </li></ul><ul><li>Depends on the depth and size. </li></ul><ul><li>How fast can tsunami waves move? </li></ul><ul><li>475 mph in 15,000 feet of water last slide, copy the links. </li></ul>
