Abstract
- Rainfall-induced landslides are a very common occurrence in hilly regions in West Java Province. Efforts to mitigate the landslide hazard require knowledge about the landslide hazard characteristics. This paper presents the results of an analytical study aimed to determine the sliding surface and to estimate the run-out distance and velocity of the Pasirjambu landslide, Bandung Regency. For these objectives, slope stability analyses were conducted using pyBIMstab and SLOPE/W software, and the run-out distance and velocity were predicted using the center of the mass approach. The results of slope stability analysis show that a good agreement of sliding surface location for a critical safety factor was obtained using both slope stability software. The predicted run-out distance and velocity indicate that the Pasirjambu landslide is likely to exhibit a long run-out of 87 m and move at a velocity of about 8.3 m/s. Thus, the Pasirjambu landslide hazard would pose a significant risk to the residents below the landslide zone. [ABSTRACT FROM AUTHOR]
