This book begins with the dynamic characteristics of the covering layer-bedrock type slope, containing monitoring data of the seismic array, shaking table tests, numerical analysis and theoretical derivation. Then it focuses on the landslide mechanism and assesment method. It also proposes a model that assesing thhe hazard area based on the field investigations. Many questions, exercises and so…
Still a single word on the built up of the volcano as appears from the exposures out side the crater. In all ravines visited by the author, this are the lahar Badak, the lahar Siwalan, the Kali Ijir and the lahar ligobo, the number of lava out flows was not to be called a few. On portrait 17 we see more of such andesite break-through exposed in the ravine of the lahar Ngobo. Remarkable is the f…
The objective of landslide hazard zonation is subdivision of an area into zones with an equal susceptibility to or probability for the occurrence of mass movements. Many different methods have been proposed in the literature. These methods have in common the combination and integration of a series of input maps, which is a time consuming process if done manually.
