The Proceedings of the 11th International Conference and Field Trip on Landslides deals with landslides in soil and rock as well as snow and slush avalanches. It contains analyses, experimental investigations and stability evaluation of landslides in soil. Case records with detailed surveys illustrate the topographic conditions and the movements that take place. Numerous case records from rock slides give new information about the extent of such slides and the geological conditions where such slides occur. The sliding mechanism is described and modelled and there is consideration of the climatic conditions which have a significant effect on the triggering of such slides. Several papers deal with the monitoring of snow and slush avalanches. Additional studies include models and experiments that contribute to an understanding of what happens in the field. Authors and co-authors from 18 countries contributed to this interesting collection of scientific work. The publication is an important addition to what has already been written on these topics and is a valuable reference for a better understanding of landslides and avalanches.
