    Cecil Cecil Presentation Transcript

    • Cecil Greene Austin Guyer Mrs. Smith 3rd Hour April 8, 2011 Earthquake Project
    • Basic Background Information
      • 1.)What is an earthquake?
      • An series of vibration in the Earths crust by the abrupt rupture of rocks.
      • 2.) How are earthquakes measured?
      • Magnitude. 3.)What does magnitude mean?
      • The strength of an earthquake based on seismic waves.
      • 3.)How is magnitude measured?
      • Richter scale
    • Damage Caused by Earthquakes
      • Tsunamis
      • Buildings falling
      • Landslide
      • Liquefaction
    • Waves
      • What are earthquake waves called?
      • Seismic wave.
      • What two types of seismic waves are there?
      • Body and Surface waves.
      • What two types of body waves are there?
      • P waves and S waves.
    • Body Waves
      • How do P waves travel?
      • Compress and expand.
      • How do S waves travel?
      • Side to side and make the ground roll like oceans.
      • Which move faster?
      • P waves.
    • Elastic Rebound
      • A theory of earthquakes that envisages gradual deformation of the fault zone.
      • An elastic rebound occur in a transform boundary.
    • The Tohoku Earthquake
      • This quake occurred at :
      • Friday March 11
      • This quake occurred
      • Tokyo Japan
      • The magnitude of this quake was
      • 9.0
    • Effects on the environment/earth
      • Shifted the cost line 13 feet to the east.
      • Shifted earth on its axis by about 6.5 inches.
      • Cause the planet to rotate somewhat faster.
    • Effects on the People of Japan
      • Nuclear reactor leaks radiation.
      • They are homeless.
      • Lost love ones
    • Effects on the Economy of Japan
      • Can not manufacture as many parts.
      • Cant export produce if its contaminated.
      • Damaged factories cant make products to export.
    • GPS Sensors
      • One interesting fact about this earthquake is that it moved several GPS sensors. This will require.. Maps, property records, and driving directions to be changed.
      • How does elastic rebound explain this movement?
      • Because Japans location was changed on the earth.
    • Tsunamis
      • What is a tsunami?
      • An large ocean wave that is caused by earthquakes or volcanic eruptions.
      • How do tsunami waves appear at sea?
      • An under water earthquake or volcanic eruptions.
      • How high can tsunami waves be?
      • 98 feet.
      • How fast can tsunami waves move?
      • 5 hundred and 89 miles per hour.
