4- What are the 3 types of faults? What happens at each type of fault line?

5- What is the difference between the focus and the epicenter?

6- What are the 3 kinds of seismic waves? Which one arrives first? Which one causes the most damage?

7-How many points do you need to determine the epicenter?

8-What are the 4 kinds of damage we listed that can be caused by earthquakes?
