Investigating earthquakes

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