  1. 1. Earthquakes Aubrey Meagher Brooklyn Jerzewski Mrs.Smith 5th Hour April 8, 2011
  2. 2. Basic Earthquake Information <ul><li>An earthquake is the shaking that results from the movement of rock beneath earth’s surface. </li></ul><ul><li>Earthquakes are measured by magnitude </li></ul><ul><li>Magnitude means the strength based on seismic waves. </li></ul>
  3. 3. Damage caused by earthquakes <ul><li>Earthquakes can cause landslides, tsunamis, and can knock down buildings. </li></ul>
  4. 4. Waves <ul><li>Earthquake waves are called seismic waves. </li></ul><ul><li>Two types of seismic waves are surface waves and body waves. </li></ul><ul><li>Two types of body waves are primary waves ( P- waves) and secondary waves( S- waves). </li></ul>
  5. 5. Body Waves <ul><li>P- waves travel at about 1 to 5 miles per second depending on the material it’s traveling through. </li></ul><ul><li>S- waves come after P- waves. </li></ul><ul><li>P- waves move faster than S- waves. </li></ul>
  6. 6. Elastic Rebound <ul><li>An elastic rebound is an explanation for how energy is spread during earthquakes. </li></ul>
  7. 7. The Tohoku Earthquake <ul><li>The earthquake occurred Friday March 11, 2011 at 2:46 pm at epicenter time. </li></ul><ul><li>The quake occurred at 38.322 degrees north, 142.369 degrees east. </li></ul><ul><li>The magnitude of this quake was 9.0, near the northeast coast of Honshu, Japan. </li></ul>
  8. 8. Effects on the Environment <ul><li>Tsunamis </li></ul><ul><li>Landslides </li></ul><ul><li>Buildings collapse </li></ul><ul><li>The crust of the Earth can separate </li></ul>
  9. 9. Effects on the people of Japan <ul><li>Destroys homes </li></ul><ul><li>Destroys work places </li></ul><ul><li>Injures/kills people </li></ul><ul><li>People missing </li></ul>
  10. 10. Effects on the economy of Japan <ul><li>Sony’s six factories in the region were affected by the earthquake </li></ul><ul><li>No idea when Sony will re-open </li></ul><ul><li>Assembly plants for Toyota, Honda, Nissan were closed </li></ul><ul><li>The Japanese economy threatens to suffer another bout of recession </li></ul><ul><li>Nuclear plants have problems </li></ul>
  11. 11. GPS Sensors <ul><li>One interesting fact about the earthquake in Japan is that it moved several GPS sensors. </li></ul><ul><li>This will require all GPS sensors to be reset </li></ul><ul><li>Certain things wouldn’t be there because of elastic rebound </li></ul>
  12. 12. Tsunamis <ul><li>An unusually large sea wave produced by a seaquake or undersea volcanic eruption </li></ul><ul><li>Ranges from 3-1,640 feet </li></ul><ul><li>At the speed of a commercial jet plane </li></ul>
