  2. 2. Basic Background Information <ul><li>What is an earthquake? </li></ul><ul><li>An earthquake is a vibration which travels through the Earth’s crust. </li></ul><ul><li>How are earthquakes measured? Earthquakes are measured using a seismograph. They are usually measured in magnitude, but can be measured using the Marcelli Scale (which measures damage). </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>The size and/or amount of something. </li></ul><ul><li>How is magnitude measured? Magnitude used to be measured using the Richter Scale, but are now measured using the Moment Magnitude Scale. </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>Cracks in the ground </li></ul><ul><li>Objects breaking </li></ul><ul><li>Buildings are destroyed </li></ul><ul><li>Explosions and fires </li></ul>
  4. 4. Waves <ul><li>What are earthquake waves called? </li></ul><ul><li>Seismic w aves </li></ul><ul><li>What two types of seismic waves are there? </li></ul><ul><li>They are called P waves and S waves </li></ul><ul><li>What two types of body waves are there? </li></ul><ul><li>Surfac e waves a nd seismic waves </li></ul>
  5. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>P wa ves trav el in all directions </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>S wav es tra vel u p and dow n </li></ul><ul><li>Which move faster? </li></ul><ul><li>S wav es trav el faster </li></ul>
  6. 6. Elastic Rebound <ul><li>Th eor y tha t states tha t earthquak  envisages gr adual de formation of the fault zone wi thout fau lt slippage until friction is overcome </li></ul><ul><li>It occu rs at a transfo rm bound ary </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>23:3 2 </li></ul><ul><li>This quake occurred </li></ul><ul><li>At Honshu Jap an </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>7.9 </li></ul>
  8. 8. Effects on the environment/earth <ul><li>Cracks </li></ul><ul><li>Fir es </li></ul><ul><li>Nucle ar expo sure </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>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.
