Eruptions of Mount St. Helens: Past, Present, and Future

This on-line book, published by the United States Geological Survey (USGS), covers the 1980 eruption of Mount St. Helens in Washington state. There is a discussion of the events leading up to the eruption, as well as an explanation of the mountain's volcanic history. Immediate effects are covered, including the ash falls, pyroclastic flows, and debris. Post-eruption topics include subsequent activity after the May 18th blast, comparison with other volcanoes, and possible future behavior. Additional reading resources are given for further reference.
