Earthquake data

  1. 1. Analyzing and Predicting Earthquake Data (GIS) Sally Kafelghazal C7
  2. 2. Big Earthquakes Data
  3. 3. Significant Earthquakes Data
  4. 4. 2010 Data
  5. 5. All Combined Data
  6. 6. 10 Overdue Earthquake Locations 1 2 3 4 5 6 7 9 10 8
  7. 7. Reason’s Why I Chose These Locations… <ul><li>1. I chose this area because the previous earthquakes were very big, significant, and a lot of them occurred recently. Also because that is a subduction zone which may cause more earthquakes to occur. </li></ul><ul><li>2. This area was chosen because there were some earthquakes that occurred here and because this is where there are transform plate boundaries and where the San Andreas fault is. I believe that will cause more earthquakes soon. </li></ul><ul><li>3. I chose this area because it is part of the border for many Plate Boundaries and is where there is a subduction zone. Also because there hasn’t been many recent earthquakes so I predict one will occur soon because it is a seismic gap. </li></ul><ul><li>4. I chose this area because many earthquakes occurred here, many being big and significant. I also chose this area because there is relative motion of the South American plate and the Nazca plate, both going toward this area. </li></ul><ul><li>5. This area was chosen because there is a large cluster of significant earthquakes that occurred here and none have recently taken place so I believe it is a seismic gap. Also, because there is a convergent plate boundary here. </li></ul>
  8. 8. <ul><li>6. I chose this area because it is the plate border between the Eurasion and Indian-Australian plates and there is a subduction zone here. On top of that, there is relative motion of both plates going toward that subduction zone which may cause more earthquakes. </li></ul><ul><li>7. This area was chosen because there are a lot of significant, big, and recent earthquakes that occurred here. There is a subduction zone located here too. </li></ul><ul><li>8. I chose this area because there is relative motion of the Pacific and Indian-Australian plates going toward the subduction zone located in this area. Also because there were a lot of earthquakes that recently occurred here. </li></ul><ul><li>9. I chose this area because it is near a mid-ocean ridge and is a convergent plate boundary. Also because many big, significant, and recent earthquakes occurred here so I think one might occur soon. </li></ul><ul><li>10. This area was chosen because it is the Aleutian Trench, it is a convergent plate boundary, and has relative motion of the North American and Pacific plates going toward this area. Lastly, there were many significant earthquakes. </li></ul>Reason’s Why I Chose These Locations…
  9. 9. Follow Up Questions <ul><li>What do you notice about the contribution of these earthquakes? </li></ul><ul><li>The division of these earthquakes correspond with the boundaries among the tectonic plates. </li></ul><ul><li>How does the contribution of these earthquakes compare to the others? </li></ul><ul><li>Big earthquakes tend to be strong where tectonic plates are colliding, rather than pulling apart. Concentrations of big earthquakes border the Pacific ocean in the pattern often described as the Ring of Fire. </li></ul>What factors influence earthquake predictions? <ul><li>Some factors are the strength and duration of seismic shaking and the occurrence of earthquakes in the past and their properties (magnitude, etc.) </li></ul>
  10. 10. Follow Up Questions <ul><li>What have you learned about earthquakes and earthquake prediction? </li></ul><ul><li>I have learned many things. One thing I have learned was that an earthquake is caused by the release of energy in earth’s crust which creates seismic waves. I have also learned that earthquakes occur where convergent, transform fault, and divergent boundaries are at. I also learned that scientists study historical records of earthquakes, use devices to measure uplift, strain rocks near active faults, and study seismic gaps for earthquake prediction. </li></ul><ul><li>Where on Earth do most of the really big earthquakes occur? </li></ul><ul><li>Big earthquakes occur along where convergent plate boundaries, divergent plate boundaries, and transform fault boundaries are. Also, where there is plate motion. According to my “Big Earthquake Data” map, most large earthquakes occur where there are convergent plate boundaries. </li></ul>
