Abstract

Landslides is one of the natural disasters that often occur in Pesisir Selatan Regency. According to the Geological Agency, Center for Volcanology and Geological Hazard Mitigation, in August 2015, all areas in Pesisir Selatan Regency were divided into medium to high levels for soil movement. This resulted in considerable losses, including transportation infrastructure in the form of roads which is one of the important and vital aspects to accelerate the pace of national development. The location of the Pesisir Selatan Regency which plays an important role as a liaison between regions and even between provinces is also very important, so that an alternative action is needed to avoid losses due to landslides and damage to road infrastructure in the region.
