  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 the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating. </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>We use a device that marks the waves of the earthquake. </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>greatness of size or amount. </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>tsunamis </li></ul><ul><li>“ a series of giant waves .” </li></ul><ul><li>Aftershocks </li></ul><ul><li>Make matters worse. </li></ul><ul><li>And unfortunately Death tolls go up </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>
  5. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>Travels through solids and liquids </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>. Travels through solids </li></ul><ul><li>Which move faster? </li></ul><ul><li>P waves </li></ul>
  6. 6. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>2:46 pm </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 </li></ul>

  10. 10. GPS Sensors <ul><li>One interesting fact about this earthquake is that it moved several GPS sensors. This will require modifications. Japan moved 5 inches closer to the u.s. </li></ul><ul><li>How does elastic rebound explain this movement? </li></ul><ul><li>The plates are moving and the plate that japans on moved. </li></ul>
  11. 11. earthquakes <ul><li>Scientists are interested in earthquakes I think there deadly and dangerous </li></ul><ul><li>A positive thing about earthquakes is they form mountains and other landforms </li></ul><ul><li>A negative thing about earthquakes is that they destroy </li></ul><ul><li>So earthquakes create and destroy. Wow. </li></ul>
