Determination of Slip Surface Using 2D Geoelectric Resistivity Method and Laboratory Analysis for Landslide Prone Area Pesawaran, Lampung

Abstract

Padang cermin sub district is the only access to beach tourism in Pesawaran District, which is the main tourist destination in Lampung. Along Padang cermin road consists of cliffs and hills that are vulnerable to landslides. so it is necessary to study the vulnerability of landslides in the area. 2D geoelectric measurements have been carried out in the Padang cermin area to find out the resistivity values that can be used to determine the land that makes up the slope and the skid plane. From the measurement results it is found that in the Padang cermin area there are five layers of soil in a row namely clay, clay sand, Alluvium, Sandstones and limestone. Slip surface area is at the boundary between the fourth and fifth layers at a depth of 39m.
