Analisis Potensi Longsor Pesisir Pantai Menggunakan Metode Geolistrik 1 Dimensi Daerah Amurang, Minahasa Selatan, Sulawesi Utara.

Abstract

Ahmad Rizal Mukhoyyar. 101218023. Coastal Landslide Potential Analysis Using 1 Dimension Geoelectrical Method Amurang Region, South Minahasa, North Sulawesi. This study contains an analysis of the potential for landslides on the Amurang coast, with the aim of determining areas prone to landslides around the coast and providing disaster prevention and mitigation measures. The main method used is an analysis of 1-dimensional geoelectrical data and drill log data in the study area by providing subsurface lithology information. Then, the results of the analysis will determine the potential for coastal landslides using the land cover map of the study area. In addition to these data, there are other additional data such as the Digital Elevation Model (DEM) and the groundwater table to assist in the analysis of potential landslides in each geoelectrical data and drill log data. The results of these data will determine the potential for coastal landslides, which are dominantly high (prone) on the coast with a distance of ±30 meters, medium with a distance of 30-100 meters, and low with a distance of ±100 meters. Based on the results of an analysis of the potential for coastal landslides with high, medium and low prone conditions, mitigation methods for landslides around the coast will be carried out such as building groins, outreach to the community about mitigation of houses prone to coastal landslides / cliff areas, predictions and warnings of impending disasters are carried out by authorized agencies related to landslides such as the Meteorology, Climatology and Geophysics Agency.
