Abstract
Sukabumi District located in Southern West Java known as a region that has diverse natural characteristics, however, it is vulnerable to disasters, especially landslides. Moreover, this study focuses on Cisolok District because this region always occurred landslides every year due to topography aspect. The aim of this study is to analyze the influence of geomorphology to landslide-prone area in Cisolok District to reduce landslides. This study used overlay analysis for geomorphology mapping, while the Frequency Ratio (FR) method used for landslide-prone area mapping. Several physical variables used in this study such as slope, elevation, lithology, geological structure, road network, stream network, land use, soil type, rainfall, and landslide location. The result shows that the study areas have diverse geomorphology units dominated by volcanic slope with steep topography. While landslide-prone area consist of four classes : namely 17,03% low, 62,05% medium, 14,4% high, and 6,51% very high. Variety of landslide vulnerability in study area influenced by terrain form, land genesis, and geomorphic process.
Highlights
One of the natural disasters that often occurred in Indonesia is landslides [1]
Morphology of study area divided into six classes there is flat area dominated by slope
According to information from BPBD officer, all landslides triggered by steep slopes and unstable land
Summary
One of the natural disasters that often occurred in Indonesia is landslides [1]. It becomes an annual disaster, especially during the rainy season. Landslides in Indonesia usually occurred in steep topography and in weathered volcanic rocks [2]. In 2017, there were 848 landslides occurred in Indonesia which resulted in 163 deaths [3]. West Java Province is one of the areas with the most landslides, precisely in Sukabumi Regency [4]. There has been a major landslide, hoard a residential block in the Halimun National Park area, Cisolok District. Landslide in Cisolok triggered by high rainfall, steep slope, and unstable land [4]
