Using the Schlumberger configuration resistivity geoelectric method to analyze the characteristics of slip surface at Solok

Abstract

Landslides are the frequent disaster in the wavy topography zone, such as Sungai Lasi Solok. Landslide disaster was difficult to predict. Based on these conditions, we need to do the research. The aims of the research were to find out the characteristic of landslide slip surface at Sungai Lasi Solok base on Geoelectric Data. Data were collected by Automatic Resistivity Multi-electrode using Resistivity Geoelectric Method with Schlumberger configuration. The interpretation of the Geoelectric data was used Two Dimensions Least-Square Inversion Method. Characteristics of the landslide such as were estimated by Trigonometry theory in order to get both the angle and the depth of landslide slip surface. The results of the research are both the angle and the depth of the slip surface is 40 degrees and 14 meters.
