A landslide occurrence may involve a rapid movement and poses a substantial risk to a densely populated area. Thus, an effort to reduce the substantial landslide risk requires understanding landslide velocity and run-out distance. The study presented in this paper attempts to estimate the run-out distance and velocity of a potential landslide movement in the Sidamukti area, Bandung Regency, using two different slope stability analysis software and the center of mass approaches. The slope stability analysis results show that the estimated potential landslide masses obtained from PyBimstab software show a good agreement with those obtained by Geostudio software. Accordingly, the results of the center of mass analysis of both estimated landslide masses resulted in a run-out distance of approximately 60 m and a velocity of more than five m/s. Thus, the landslide in the study area can be classified as an extremely rapid landslide. © 2023 Author(s).
