Abstract

Landslides are most common in steep areas with heavy rainfall. Aside from rainfall, there are numerous other factors that contribute to landslides. The presence of slip fields in the subsurface layer is one of the primary causative factors. South Makale is one of the sub-districts in Tana Toraja Regency that is located in the mountains, where landslides frequently occur, claiming lives. The purpose of this study was to determine the slip area of potential landslides in three sub-districts, which are Sandabilik, Tiromanda, and Randan batu villages. The geoelectric method with the Wenner-Sclumberger configuration type was used. The measurement data is in the form of rock resistivity values, which are then interpreted based on the rock layer type. The findings revealed that the Sandabilik and Randan Batu villages were landslide risk areas. Sandabilik Village has a slip area in the form of lava rock at a depth of 6.5 - 19.8 meters on line 1 and 1.5 - 16 meters on line 2. Rocks of the same type can also be found in Randan Batu Village, a landslide point with depths ranging from 2 to 16 meters on line 1 and 5 to 20 meters on line 2.
