    • Replace this with YOUR title Customize your font!! Jennifer Bosworth and Brittany east Mrs.. Smith 5TH April 8, 2011
    • Basic Background Information
      • What is an earthquake?
      • The shaking that results from the movement of rock beneath earths surface.
      • How are earthquakes measured?
      • The instrument used to measure earthquakes is called a seismograph.There are three ways of measuring earthquakes the mercalli scale,the Richter scale,and the moment magnitude scale
      • What does magnitude mean?
      • Magnitude is the measurement of earthquake strength based on seismic waves and movement along fault.
      • How is magnitude measured?
      • It is measured in three different types of scales(mercalli scale,Richter scale,and moment magnitude scale)
    • Damage Caused by Earthquakes
      • Landslides
      • Buildings falling off foundations
      • Wide cracks in the ground
      • tsunamis
    • Waves
      • What are earthquake waves called?
      • Seismic waves(P waves, S waves ,and surface waves)
      • What two types of seismic waves are there?
      • P waves and S waves.
      • What two types of body waves are there?
      • P waves and S waves.
    • Body Waves
      • How do P waves travel?
      • They leave the focus by compressing and expanding to earths surface.
      • How do S waves travel?
      • They leave the focus by moving from side to side up to earths surface
      • Which move faster?
      • P waves
    • Elastic Rebound
      • An elastic rebound is where a bend in earths surface occurs and breaks the land so it is straight.
      • An elastic rebound occurs at a transform boundary.
    • The Tohoku Earthquake
      • This quake occurred at :
      • 5:46
      • This quake occurred
      • tohoku
      • The magnitude of this quake was
      • 9.0
    • Effects on the environment/earth
      • Nuclear radiation was released into the air and water.
      • The problems were reported at two nuclear plants run by Tohoku Electric Power Co
    • Effects on the People of Japan
      • Many people had to flee buildings.
      • People who had houses near the power plants had to be evacuated.
      • Millions of dollars worth of damage was needed to help repair.
    • Effects on the Economy of Japan
      • Millions of dollars were spent on the repair from the earthquake.
      • Thousand of homes were destroyed.
      • Many of people were killed
    • GPS Sensors
      • One interesting fact about this earthquake is that it moved several GPS sensors. This will require …new gps maps.
      • How does elastic rebound explain this movement?
    • Tsunamis
      • What is a tsunami?
      • An unusualy large sea wave caused by a sea quake..
      • How do tsunami waves appear at sea?
      • Type your answer here. You can erase the question.
      • How high can tsunami waves be?
      • Type your answer here. You can erase the question.
      • How fast can tsunami waves move?
      • Type your answer here. You can erase the question.
