1. Tsunamis have occurred many times in history. As a matter of fact, legends abound about them. Conduct an Internet search to find out:

a.Where have tsunamis occurred in the last 100 years?
b.Which suboceanic faults caused them?
c.What magnitude on the Richter scale earthquake caused them?
d.How much damage was done to the land and property?

It might also be helpful to correspond through e-mail or talk in a web discussion site with a seismologist or geologist. Prepare a multimedia presentation to share what you have learned with your classmates. Below is a link to get you started:
