Most earthquakes follow plate boundaries and large quakes of magnitude 7 or greater primarily occur along convergent plate boundaries. About 50% of large quakes happen within 100 miles and 70-75% are within 200 miles of these boundaries. Seismologists use new tools like satellites to detect infrared radiation and magnetic signals to better predict earthquake locations, with the area around Crete cited as being overdue for a significant quake.

2. Part #3 1.)Q: What do you notice about the distribution of these earthquakes? A: Most of the earthquakes follow the pattern of the plate boundaries. 2.)Q: How does the distribution of these earthquakes compare to the others? A: There are a lot more big earthquakes in areas where the plates are colliding, like the Ring of Fire.

3. Part #3 Cont. 3.) Q: What type of plate boundary is associated with earthquakes that have a magnitude of 7.0 or greater? A: Convergent plate boundaries 4.) Q: What percentage of big earthquakes occurs within 100 miles of a convergent plate boundary? A: About 50% 5.) Q: What percentage of big earthquakes occurs within 200 miles of a convergent plate boundary? A: About 70 to 75%

Part #4 1.)Top 10 List of Places Overdue for an Earthquake: Area around Crete California Coast Afghanistan Pakistan area Malaysia Spain and Portugal New Guinea East Upper Russia New Zealand Area around Thailand Latin America 2.) Q:What new tools and techniques are seismologists using to help them better predict earthquakes? A: They are using satellites and searching for infrared radiation, as well as detecting magnetic signals by satellite. The place with the next big earthquake will be Crete

5. Part #4 Cont. 2.) Q: What have you learned about earthquakes and earthquake prediction? A: Some things I have learned about earthquakes and earthquakes prediction are: Earthquakes follow plate boundaries Most big earthquakes happen on convergent plate boundaries Seismologists use satellites to search for radiation Earthquakes can be predicted quite easily 3.) Q: What factors influence earthquake prediction? A: Some factors that influence earthquake prediction are: The time sense the last earthquake The location of prediction If on a boundary, the boundary type Amount of previous earthquakes on location 4.) Q: Where on Earth do most of the really big earthquakes strike? A: Most of the really big earthquakes happen on Tectonic and Convergent plate boundaries.
