4. Why does California have more earthquakes than Florida? California has a higher hazard zone than Florida because California’s hazard zone is 32+ and Florida’s hazard zone is only 0-2. California has a higher hazard zone than Florida because California’s hazard zone is 32+ and Florida’s hazard zone is only 0-2.

5. What hazard zone are we located in? Our hazard zone is located in the 0-16 area. Our hazard zone is located in the 0-16 area.

The earthquake Sumatra. The earthquake Sumatra. It occurred on December 26,2004. It occurred on December 26,2004. It happened in South East Indonesia. It happened in South East Indonesia.

7. What are the three types of plate boundaries? Convergent plate boundary Convergent plate boundary Transform plate boundary Transform plate boundary Divergent plate boundary Divergent plate boundary

8. What is a Convergent plate boundary? A convergent plate boundary is when two plates come together or converge. A convergent plate boundary is when two plates come together or converge.

9. What is a Divergent plate boundary? A divergent plate boundary is when two plates move away from each other. A divergent plate boundary is when two plates move away from each other.

10. What is a Transform plate boundary? A transform plate boundary is when two plates slip past each other, moving in opposite directions. A transform plate boundary is when two plates slip past each other, moving in opposite directions.

11. What are tsunamis, what causes them, and how fast do they travel? Tsunamis are gigantic ocean waves. Tsunamis are gigantic ocean waves. They are normally set off by undersea earthquakes. They are normally set off by undersea earthquakes. Tsunamis travel at about 500 mph. Tsunamis travel at about 500 mph.

12. Tsunami in Japan

13. What are the two types of energy waves, how do they differ, which wave travels faster? The two types of waves are primary waves and secondary waves. The two types of waves are primary waves and secondary waves. They are different because primary waves move in a compressional motion and secondary waves move in a shear motion. They are different because primary waves move in a compressional motion and secondary waves move in a shear motion. Primary waves travel faster. Primary waves travel faster.

14. How much more energy is released in a 7.2 earthquake than by a 6.2 earthquake? A 7.2 earthquake creates 10 times more motion in the ground than a 6.2 earthquake, the 7.2 earthquake releases about 32 times more energy. A 7.2 earthquake creates 10 times more motion in the ground than a 6.2 earthquake, the 7.2 earthquake releases about 32 times more energy.

15. What applications does seismology have besides measuring magnitude and location of earthquakes? Other applications would be that seismology provides means to monitor for nuclear used to test and build weapons. Other applications would be that seismology provides means to monitor for nuclear used to test and build weapons.

16. Where did most of the earthquakes happen last week? Many of the earthquakes were in different areas of the United States. Many of the earthquakes were in different areas of the United States.

17. Can Scientists Predict Earthquakes? No! No! Scientists cannot predict earthquakes and they may never be able to. Scientists cannot predict earthquakes and they may never be able to. Scientist have tried to predict many earthquakes but never have succeeded. Scientist have tried to predict many earthquakes but never have succeeded.

18. How do scientists know where an earthquake actually occurred? They know where earthquakes occurred based on how the plates move in the earth and the fault zone locations. They know where earthquakes occurred based on how the plates move in the earth and the fault zone locations.
