  • 1. Replace this with YOUR title Customize your font!! Jennifer Bosworth and Brittany east Mrs.. Smith 5TH April 8, 2011
  • 2. Basic Background Information <ul><li>What is an earthquake? </li></ul><ul><li>The shaking that results from the movement of rock beneath earths surface. </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>The instrument used to measure earthquakes is called a seismograph.There are three ways of measuring earthquakes the mercalli scale,the Richter scale,and the moment magnitude scale </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>Magnitude is the measurement of earthquake strength based on seismic waves and movement along fault. </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>It is measured in three different types of scales(mercalli scale,Richter scale,and moment magnitude scale) </li></ul>
  • 3. Damage Caused by Earthquakes <ul><li>Landslides </li></ul><ul><li>Buildings falling off foundations </li></ul><ul><li>Wide cracks in the ground </li></ul><ul><li>tsunamis </li></ul>
  • 4. Waves <ul><li>What are earthquake waves called? </li></ul><ul><li>Seismic waves(P waves, S waves ,and surface 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 waves and S waves. </li></ul>
  • 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>They leave the focus by compressing and expanding to earths surface. </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>They leave the focus by moving from side to side up to earths surface </li></ul><ul><li>Which move faster? </li></ul><ul><li>P waves </li></ul>
  • 6. Elastic Rebound <ul><li>An elastic rebound is where a bend in earths surface occurs and breaks the land so it is straight. </li></ul><ul><li>An elastic rebound occurs at a transform boundary. </li></ul>
  • 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>5:46 </li></ul><ul><li>This quake occurred </li></ul><ul><li>tohoku </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>9.0 </li></ul>
  • 8. Effects on the environment/earth <ul><li>Nuclear radiation was released into the air and water. </li></ul><ul><li>The problems were reported at two nuclear plants run by Tohoku Electric Power Co </li></ul>
  • 9. Effects on the People of Japan <ul><li>Many people had to flee buildings. </li></ul><ul><li>People who had houses near the power plants had to be evacuated. </li></ul><ul><li>Millions of dollars worth of damage was needed to help repair. </li></ul>
  • 10. Effects on the Economy of Japan <ul><li>Millions of dollars were spent on the repair from the earthquake. </li></ul><ul><li>Thousand of homes were destroyed. </li></ul><ul><li>Many of people were killed </li></ul>
  • 11. GPS Sensors <ul><li>One interesting fact about this earthquake is that it moved several GPS sensors. This will require …new gps maps. </li></ul><ul><li>How does elastic rebound explain this movement? </li></ul>
  • 12. Tsunamis <ul><li>What is a tsunami? </li></ul><ul><li>An unusualy large sea wave caused by a sea quake.. </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>
  • 13. Websites Used <ul><li>Copy and paste the URLs of the websites and articles you used. </li></ul>
