Abstract

This Kamojang area is an Indonesian geothermal field that produces electricity since 1983. As many other geothermal fields in Indonesia, Kamojang area is located in high relief volcanic terrain where landslides frequently occur. Hydrothermal alteration of volcanic rocks is an important geological process which reduce slope stability due to the reduction of the rock mass strength properties. Landslides in a geothermal area are hazards that can adversely affect roads, pipelines, as well as injection and geothermal wells. The aim of this study is to enhance the understanding of landslide processes in highly weathered and hydrothermal altered volcanic rock masses based on field, laboratory and numerical modelling studies. Exemplarily for this geological situation, the study site of the geothermal area of Kamojang in Indonesia was chosen. This article presents an overview of the study area and some preliminary results from a data compilation study and a field survey during this summer.
