Geomorphology of Landslide Prone Area in Cimanggung District, Sumedang Regency, West Java

The research area is located on Cimanggung District, Sumedang Regency, West Java Province at coordinate 6°51'33,0" S - 6°59'38,6" S and 107°42'26,2" E -107°58'44,5" E. This research aims to identify and characterize the geomorphology features related to landslide prone area in the Cimanggung area. This research was conducted using the studio analysis method with several supporting data such as: slope, drainage patterns, geological maps, and satellite images of the Cimanggung area. The results of the research show that the Cimanggung area is located between the morphology of volcanic hills with steep to very steep slopes. Radial and subparallel drainage patterns were identified in the Cimanggung area indicating that the area is relatively close to the hilltop and hillsides. Moreover, the research area is geologically composed by the dominance of undifferentiated young volcanic products. On the other hand, the satellite images show that the Cimanggung area and its surroundings have undergone land use changes, especially into residential areas. These conditions indicate the Cimanggung area has a fairly high level of landslide susceptibility. Therefore, a systematic and integrated regional planning program is needed to minimize the potential for landslides that can occur.
