Synopsis: Tsunamis harbor an element of surprise: In the deep ocean, tsunami waves pass unnoticed beneath boats, yet they rise to dangerous heights near shore. How do tsunamis work? What was the worst tsunami in recorded history? How does a tsunami warning system work?

Questions
1. Why can't sailors detect a tsunami mid-ocean? What makes the waves rise "out of nowhere" near the coast?
2. How does the current tsunami warning system work? What technology is currently being used? What technologies may be used in the future?
3. What should you do if, during a trip to a beach on the Pacific coast, you feel a large earthquake? Where should you go? For how long?
Lesson Plans/Activities
1. Tsunami Effects! After developing an understanding of the physics of tsunami waves, students research effects of a recent tsunami on a country of their choice. Recommended for grades 9-12.
2. Tsunami Experiment! Students collect data to show the relationship between wave speed and water depth, an important factor in tsunami behavior. Recommended for grades 10-12.
3. Makin' Waves! Students compare the behavior of waves in the open ocean or in a narrow fjord. Recommended for grades 6-8.
4. Wave Watch! Photos and animations within this multi-page online article allow students to visualize how tsunamis work and how destructive they can be. Recommended for grades 5-12.
