    Investigating earthquakes Investigating earthquakes Presentation Transcript

    • Investigating Earthquakes Anne Wampler C6 C6 C6
    • CONTENTS
      • Our Maps
      • What have you learned about earthquakes and earthquake prediction?
      • What factors influence earthquake prediction?
      • Where on Earth do most of the really big earthquakes strike?
    • Our maps
    • Significant AND BIG Quakes
      • These are the quakes ranging in magnitude from 7 to 10 that occurred from 2150 BC to 1994 AD. Each pink dot represents an earthquake.
      These are all of the earthquakes above magnitude 4 which occurred in 2011. Each yellow dot represents an earthquake 2011 QUAKES
    • Earthquakes and Earthquake Prediction Earthquake Prediction Earthquake Prediction
    • THings i learned
      • It is possible to predict fairly accurately when an earthquake is due.
      • the methods which scientists use to predict earthquakes
      • that some types of plate boundaries are more prone to earthquakes than others
      Put picture of both Sig_Big and 2010-11
    • Methods of Prediction
      • Mostly, scientists today predict earthquakes by looking at areas where pressure is building up and, judging by the recency of the last quake, guessing at the general date of the next.
      • Satellite radar can sense any plate movement, even at the slow rate of 1mm per year.
    • Future methods
      • Satellites may be able to predict earthquakes by sensing the infra red light that is produced by the pressure build up in the rock.
      • Scientists may be able to use the miniscule fluxuations in earth’s magnetic field that occur just before major earthquakes.
    • Factors
    • Location
      • proximity to plate boundaries
        • The further a place is from a boundary, the less likely it is to have a major earthquake.
      • type of plate boundary
        • Most major earthquakes occur near convergent plate boundaries.
    • Plate Boundaries
      • The blue lines mark the convergent plate boundaries which I think are most likely to cause earthquakes soon because they havd not had a major quake recently.
    • Major earthquake locations
    • Top 10 Countries that are due for an earthquake that are due for an earthquake
      • Mainland United States
      • Mexico
      • Russia
      • Venezuela
      • Colombia
      • Algeria
      • Spain
      • Portugal
      • India
      • New Zealand
    • Reasons
      • I believe that these 10 countries are most likely to have a major earthquake soon because they are:
        • on convergent boundaries
        • have had large earthquakes in the past
        • have not had a significant earthquake in the past year.
    • Most likely country to have a major earthquake next
      • The United States
        • I believe this because:
          • the U.S.’s north west coast is on a convergent boundary
          • they have constant small quakes
          • that part of the boundary has not had as many major quakes as the rest of the convergent boundaries
