Description: Describes and illustrates the study of volcanoes as done at the Kilauea Volcanic Observatory in Hawaii, and also discusses the hypotheses formulated to explain volcanic origins by scientists working at this observatory. Actual eruptions and lava flows are observed from many angles including a large number of close-ups made with a telephoto lens. Scientists working at the observatory explain and diagram their hypothesis and use this hypothesis with seismological studies to follow a prediction of an eruption through the actual event.
