Host Philippe Cousteau examines the cause of volcanoes, earthquakes and tsunamis. We visit the Big Island of Hawaii, where there is still an active volcano. Then we visit a laboratory at Oregon State University that is able to simulate a tsunami. We’ll explore the damage that these massive waves cause. Then we head to the Puget Sound in Washington and discover the history of tsunamis in the Northwest with the help of geologist, Brian Atwater. We’ll learn if a tsunami will happen again on the west coast.
