Transcript

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