An assessment of expectable kinds of future eruptions and their possible effects on human life and property.

With climate change and deforestation, debris flows and debris avalanches have become the most significant landslide hazards in many countries. In recent years there have been numerous debris flow avalanches in Southern Europe, South America and the Indian Subcontinent, resulting in major catastrophes and large loss of life. This is therefore a major high-profile problem for the world's governments and for the engineers and scientists concerned. Matthias Jakob and Oldrich Hungr are ideally suited to edit this book. Matthias Jakob has worked on debris flow for over a decade and has had numerous papers published on the topic, as well as working as a consultant on debris flow for municipal and provincial governments. Oldrich Hungr has worked on site investigations on debris flow, avalanches and rockfall, with emphasis on slope stability analysis and evaluation of risks to roads in built-up areas. He has also developed mathematical models for landslide dynamic analysis. They have invited world-renowned experts to joint them in this book.

This comprehensive book traces the warning, planning, and response to the eruption of Mount St. Helens in May 1980, as seen through the eyes of key actors in the emergency. Based on first-hand accounts by 130 officials of government, private industry, and volunteer organizations--individuals who played prominent roles in preparing for and dealing with the eruption--it represents a unique overview of the problems and procedures involved in learning about, planning for, and dealing with a major disaster. Ironically, the first official warning had come as early as two years previously. More warnings came several months before the explosion. Yet many persons involved either ignored them or remained unaware that they could be affected. The book shows how this happened, suggesting steps that can be taken to insure future preparedness for large-scale emergencies.
