This study aims to identify the presence and depth of slip planes in landslide-prone areas in Lamboo Village, Moramo Subdistrict, South Konawe using the Wenner-Schlumberger configuration of the electrical resistivity method. The method involes injecting electric current into the ground and measuring the potential diffrerence to determine subsurface resistivity variations. Measurements were conducted along five survey lines to reveal subsurfaces  geological  structures  potentially  acting  as  landslide zones. The inversion results showed low resistivity zones interpreted as water-satured clay layers, which serve as slip planes. These slip zones vary in depth acroos the survey lines. The findings are crucial for landslide risk mitigation and can inform safer land-use planning for local communities
