Abstract

Abstract. The Wungkal Mountain area is a Godean hill which is probably an ancient volcano. It is an open green space area in Sleman Regency for the development of mining, housing, tile and brick industries. Because it is growing rapidly, the impact of land movement risks needs to be monitored and this is done by mapping soil movement from lithology data, soil type, land use, rainfall, and slope. The data was processed with Arc GIS software to obtain five maps from the data collected by the Analytical Hierarchy Process (AHP) method. This method is capable of calculating the weight of the landslide risk level in the Wungkal Godean mountain area. From the results of the risk mapping of ground motions, this area was found to be prone to landslides, especially in the area to the right of Mount Wungkal which is being mined for raw materials for making roof tiles and red bricks as well as for housing development. The lithology was found in the form of andesitic igneous rock which is massively altered by lithosol and grumusol soil types. Meanwhile, residential areas are safe areas for living because there has been a lot of sedimentation
