Landslides are one of the disasters that often occur in Srimartani Village, Piyungan District, Yogyakarta. The biggest cause of landslides is the steep slope and the existence of a sliding plane on the slope. This study aims to identify the sliding plane on the slopes in Srimartani Village. This research was conducted using geoelectric method Wenner configuration with a: 10 m and n: 6. The data acquisition was taken in 6 lines. Data processing was done using Res2Dinv software and the result is a 2D true resistivity cross section. The results of the interpretation of the six lines indicate the existence of a sliding plane which is characterized by low resistivity contrast at the bottom and higher resistivity near the surface. Low resistivity (10 Ωm) is identified as clay rock and high resistivity ( 10 Ωm) above is identified as surface soil.
