1. DREW M Investigating Earthquakes with ArcExplorer GIS 2. Part 3: Question #1: What do you notice about the distribution of these earthquakes? Answer: Most of these earthquakes follow the pattern of the tectonic plate boundaries almost exactly. Question #2: How does the distribution of these earthquakes compare to the others? Answer: There are many more big earthquakes in areas where the tectonic plates are colliding, such as the ring of fire. 3. Part 3 Continued: Question #3: What type of plate boundary is associated with earthquakes that have a magnitude of 7.0 or greater? Answer: Convergent Plate Boundaries Question #4: What percentage of big earthquakes occur within 100 miles of a convergent plate boundary? Answer: 47% of earthquakes Question #5: What percentage of big earthquakes occur within 200 miles of a convergent plate boundary? Answer: 71% of earthquakes 4. Part 4: Top 10 List of Places Overdue for an Earthquake(Not in order): 1. The Area around Crete, because it is on a convergent boundary. 2. The California Coast, because it is on a fault line 3. The Stan Countries (Afghanistan, etc.) because they are on a convergent boundary. 4. Malaysia, because it is on a convergent boundary, and has had many past earthquakes. 5. Spain and Portugal, because they have had many past earthquakes. 6. New Guinea, because it is on 2 convergent boundaries. 7. East Upper Russia, because there is a fault line right through it. 8. New Zealand, because it has had many past earthquakes. 9. Area Around Thailand because it has had many past earthquakes 10. Latin America because it is on a convergent boundary and has had many past earthquakes. Question #2: What new tools or techniques are seismologists using to help them better predict earthquakes? Answer: They are using satellites, and searching for infrared radiation, as well as detecting magnetic signals by satellite. Place that will have the next big earthquake: The Area Around Crete, because it is on a convergent boundary. 5. Part 4 Continued: Question #2: What have you learned about earthquakes and earthquake prediction? Question #3: What factors influence earthquake prediction? Question #4: Where on Earth do most of the really big earthquakes strike? Answer: Most of the really big earthquakes strike on Tectonic Plate Boundaries, but mostly on Convergent Type Boundaries.

  • Answer:
  • The factors that influence earthquake prediction are:
  • The time since the last earthquake
  • The location of prediction
  • If on a boundary, the boundary type
  • Amount of previous earthquakes on location (annually or otherwise).
  • Answer:
  • I have learned:
  • About Earthquakes:
  • They follow plate boundaries
  • Most big earthquakes happen on Convergent Plate Boundaries
  • About Earthquake Prediction:
  • Seismologists use satellites to measure infrared radiation and magnetic signals.
  • Earthquakes can be predicted by looking at past earthquakes
  • Earthquakes can be predicted with relative ease
