Dr. Richard Fiske (Smithsonian Institution) presents a lecture on the eruption of Krakatoa and answers viewers' questions. Introduced by Dr. Leon Silver, California Institute of Technology.
In this episode, the subject is the use of innovative methods to more accurately measure natural catastrophes, such as earthquakes, volcanoes, and hurricanes. While the scientists take their measurements there, the viewer observes a full eruption at Kilauea Volcano. Kilauea is located on the island of Hawaii, and is one of the largest and most spectacular craters in the world. It is also one of the most active volcanoes, and in this film, it puts on an amazing display of fire and power.
