Ground motion is the process of moving masses of soil or rock in the upright, horizontal and oblique directions from the original or original state, the Cianjur region has experienced many earthquakes at some time so it is necessary to study the fault zone in this area and see the geological aspects of this area. This research is located in Cugenang and surrounding areas, Cianjur Regency, West Java Province. This research aims to be able to determine the ground motion vulnerability zone according to the parameters that affect the research area, and to determine the place of evacuation zone based on the results of the ground motion vulnerability zone map in the research area. The method used is overlapping based on the classification of the Directorate of Volcanology and Geological Hazard Mitigation (DVMBG) with five parameters, namely: rainfall, land use, slope, soil type, and geology. From the results of making ground motion vulnerability zones, three types of ground motion vulnerability zones were obtained in the research area, namely: very high ground motion zone ± 72.72%, high ground motion zone ± 24.74%, and moderate ground motion zone ± 4.54%. The study area has an evacuation zone located in the east and southwest of the study area. This research can be a reference to be used as a mitigation measure for Landslide disasters in the research area.
