Mass movement of rocks in high mountains can severely injure the population and damage man made structures in these areas. This book focuses on the understanding of the mechanisms of rockslides and rockfalls using a quantitative approach. The range and velocity of these hazards are calculated to serve as a basis for evacuations and other preventive measures. Examples from four continents illustrate the necessity of this kind of information. The book contains a wealth of information for practitioners and scientists working in the field of catastrophe prevention.
