Abstract
Cimaung Village is one of the villages part of the Cimaung District which is in the southern part of Bandung. Location is right at the confluence of three remaining volcanoes namely Mount Malabar, Mount Tilu and Mount Tanjaknangsi. Its existence in this valley is very vulnerable to geological disasters, such as floods, landslides, etc. Residual activity of the three volcanoes greatly influences the geomorphological conditions. Rocks produced from volcanic activity play an important role in the formation of a distinctive geomorphology. The rocks in the Cimaung area and its surroundings are the result of volcanic activity such as lava, lava and pyroclastic. Geomorphological analysis was carried out by analyzing river flow patterns, topographic maps, slopes and landsat imagery in the form of DEM (Digital Elevation Model) as well as direct observations in the field. Results of the geomorphological analysis are poured into geomorphological maps and maps of disaster-prone areas. Geomorphological unit in the study area consists of 11 (eleven) geomorphological units, in which morphological changes are still continuing today. Main control for significant morphological changes is controlled by human activities, weathering and land clearing will continue to this day.
