Identification of the slip area of a landslide using resistivity geoelectric method

Abstract

Research on the tracking of the slip area of a landslide using resistivity geoelectric method with Wenner configuration that aims to determine the subsurface structure which is alleged potential as the slip area has been done. Measurements took place in the Dusun II of Kalora Village, Subdistrict of Kinovaro, District of Sigi by taking three measurements trajectory. Based on the results of 2D modelling using software Res2Dinv for every trajectory obtained two layers, with the first layer of resistivity value ranges <500 Ωm identified as dry sand and the second layer resistivity values ranges> 500 Ωm that identified as a conglomerate rock. Based on the 2D cross-sectional area of research, which was thought as the field boundary slip was between 7-8 m depth on the path I with the West-East direction.
