  1. 1. Earthquakes Hayley Cross and Emily Janis Mrs. Smith 5th hour April 8, 2011
  2. 2. Earthquake Background Information <ul><li>What is an earthquake? </li></ul><ul><li>Earthquakes are 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>Earthquakes are measured by seismographs. </li></ul><ul><li>What does magnitude mean? </li></ul><ul><li>The measurement of Earthquakes strength based on seismic waves and movement along faults. </li></ul><ul><li>How is magnitude measured? </li></ul><ul><li>Magnitude is measured on the Moment Magnitude Scale. </li></ul>
  3. 3. Damage Caused by Earthquakes <ul><li>Landslides </li></ul><ul><li>Building Collapse </li></ul><ul><li>Tsunamis </li></ul><ul><li>Power Outages </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>Body Waves and Surface 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. 5. Body Waves <ul><li>How do P waves travel? </li></ul><ul><li>They compress and expand like and accordion </li></ul><ul><li>How do S waves travel? </li></ul><ul><li>They vibrate up and down as well as side to side. </li></ul><ul><li>Which move faster? </li></ul><ul><li>Primary </li></ul>
  6. 6. Elastic Rebound <ul><li>A Mechanism used by geologists to explain Earthquakes and surface ruptures, seen when a deep fault’s movement breaks through to the Earth’s surface. </li></ul><ul><li>They occur at all types of plate boundaries. </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>This quake occurred at : </li></ul><ul><li>March 11, 2011 at 9:10 am eastern time </li></ul><ul><li>This quake occurred </li></ul><ul><li>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>It caused a tsunami </li></ul><ul><li>Surface ruptures </li></ul><ul><li>Landslides </li></ul>Replace these words with an appropriate image. Replace these words with an appropriate image. Replace these words with an appropriate image.
  9. 9. Effects on the People of Japan <ul><li>Oiling Blackouts </li></ul><ul><li>Damage of nuclear power plants </li></ul><ul><li>Losses of Hundreds of thousands of lives </li></ul>Replace these words with an appropriate image. Replace these words with an appropriate image. Replace these words with an appropriate image.
  10. 10. Effects on the Economy of Japan <ul><li>Production is expected to decrease </li></ul><ul><li>High costs of rebuilding. </li></ul><ul><li>Disruption of power and water </li></ul>
  11. 11. GPS Sensors <ul><li>One interesting fact about this earthquake is that it moved several GPS sensors. This will require All of the GPS sensors to be reset </li></ul><ul><li>How does elastic rebound explain this movement? </li></ul><ul><li>It can detect an objects ability to return to its original shape. </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 disturbances. </li></ul><ul><li>How do tsunami waves appear at sea? </li></ul><ul><li>Very small </li></ul><ul><li>How high can tsunami waves be? </li></ul><ul><li>From 30 to 300 feet </li></ul><ul><li>How fast can tsunami waves move? </li></ul><ul><li>30 to 500 mph </li></ul>
