  1. 1. Earthquake Project Ashley Hammon Jessica Brock Mrs. Smith 3rd hour April 8, 2011
  2. 2. Basic Background Information <ul><li>What is an earthquake? </li></ul><ul><li>A series of vibrations in the earth’s crust. </li></ul><ul><li>How are earthquakes measured? </li></ul><ul><li>Earthquakes are measured by magnitude. </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>Magnitude is the measurement of an earthquakes strength. </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>Magnitude is measured by the Richter Scale. </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>Cracks in the crust. </li></ul><ul><li>Pipe lines break. </li></ul><ul><li>Housing and buildings get damaged. </li></ul><ul><li>Tsunami’s and landslides form. </li></ul>
  4. 4. Waves <ul><li>What are earthquake waves called? </li></ul><ul><li>They are called seismic waves. </li></ul><ul><li>What two types of seismic waves are there? </li></ul><ul><li>Primary and Secondary waves. ( P & S waves) </li></ul><ul><li>What two types of body waves are there? </li></ul><ul><li>Surface waves and Body waves. </li></ul>
  5. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>P waves have the ability to travel through liquids and solids. </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>S waves can only travel through solids. </li></ul><ul><li>Which move faster? </li></ul><ul><li>Primary waves move faster than Secondary waves. They are also the first to arrive at the surface. </li></ul>
  6. 6. Elastic Rebound <ul><li>Elastic Rebound is a mechanism used by geologists to explain earthquakes and surface ruptures. </li></ul><ul><li>Elastic Rebound occurs in a divergent plate boundary. </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>5:46pm </li></ul><ul><li>This quake occurred at : </li></ul><ul><li>Northeast Honshu, Japan. </li></ul><ul><li>The magnitude of this quake was </li></ul><ul><li>9.0 </li></ul>
  8. 8. Effects on the environment/earth <ul><li>Homes and buildings were knocked over. </li></ul><ul><li>People died, which caused population to decrease. </li></ul><ul><li>Pipe lines break causing the water to not work. </li></ul>
  9. 9. Effects on the People of Japan <ul><li>No homes for many people. </li></ul><ul><li>Many people have died. </li></ul><ul><li>Many people have gone missing. </li></ul>
  10. 10. Effects on the Economy of Japan <ul><li>Ruined fishing because of the radiation leak. </li></ul><ul><li>Most of the food has radiation in it. </li></ul><ul><li>Automotive industry can’t make parts, which means no money will be coming in. </li></ul>
  11. 11. GPS Sensors <ul><li>One interesting fact about this earthquake is that it moved several GPS sensors. This will require </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>A long high sea wave caused by an earthquake or other high disturbance. </li></ul><ul><li>How do tsunami waves appear at sea? </li></ul><ul><li>They are barely visible. </li></ul><ul><li>How high can tsunami waves be? </li></ul><ul><li>30 meters. </li></ul><ul><li>How fast can tsunami waves move? </li></ul><ul><li>From 30 miles to 500 mph. </li></ul>
  13. 13. Websites Used <ul><li>Copy and paste the URLs of the websites and articles you used. </li></ul>
