Indonesia has enormous geothermal potential because most of Indonesia's territory is located in an active volcano route. One of the challenges in developing geothermal energy is that its location is located on the slopes of a Quaternary Volcanoes which is suceptible to landslides. The purpose of the research that has been carried out is to determine the distribution of landslide-hazard areas on the western slopes of the Arjuno-Welerang Volcano. The analysis was performed using the Analytical Hierarchy Process method based on morphological, geological and structural geological parameters. Geomorphological mapping was carried out by contour map analysis, then classified based on morphometry and morphogenesis. Geological mapping uses the principle of volcanostratigraphy, while mapping of geological structures is done by analyzing contour maps made by Digital Evalation Model and field checking. The high and very high landslide hazard zones are scattered along the fault zone, while the very high landslide hazard areas are located in the ancient crater valleys
