Penelitian ini bertujuan untuk mengetahui potensi longsor pada lereng kampus 2 UKI Toraja dengan menggunakan metode Geolistrik. Metode geolistrik dapat digunakan untuk pemetaan secara lateral (mapping) maupun secara vertikal (Sounding). Identifikasi perbedaan resistivitas secara lateral maupun secara vertikal dapat dilakukan dengan menggunakan konfigurasi Wenner Schlumberger. Identifikasi secara vertikal dapat dilakukan dengan menggunakan konfigurasi Schlumberger. Pengukuran geolistrik dilakukan dilakukan sebanyak 3 lintasan dengan panjang masing- masing lintasan yaitu 100 m. Nilai resistivitas yang berada pada rentang 4,21 ?m sampai dengan 43,9?m yang berada pada kedalaman 6 m sampai dengan 19,8 m maka lapisan tersebut diduga batupasir yang mengandung air (akuifer). Lapisan mengandung kuarsit diduga memiliki nilai resistivitas pada rentang 389 ?m sampai dengan 1026 ?m. Nilai resistivitas yang kurang dari 4 ?m yang berada kedalam kurang dari 2 m diduga lapisan tersebut merupakan lapisan penutup yang bersifat basah. Pada simulasi pemodelan lereng dengan menggunakan Software Geo Studio/ W 2012, diperoleh nilai Safety Factor sebesar 1,554. Dari hasil yang diperoleh dapat dikatakan bahwa lereng pada daerah penelitian dianggap stabil. Selain itu, adapun nilai parameter dari massa longsoran (Slide mass).
