Take a look at the theories behind why earthquakes occur, what makes them so hard to predict and the warning system technologies we rely on today. 


QUESTIONS: 

1. Discuss how earthquakes occur. 

2. Do you think an earthquake is the world’s scariest natural disaster? Why or why not? 

3. Scientists say animals know hours before that an earthquake will strike. How do you think this is possible?
