Implementation of the SMORPH method for mapping the susceptibility area of landslide in Bogor City

Abstract

Abstract This study aims to map landslide susceptibility areas in Bogor City. The method used is the modified SMORPH method. the main parameters in this method are the slope angle and slope shape. Calculation of slope shape using curvature algorithm. The results showed that the widest medium and high hazard classes were in the South Bogor Subdistrict with a percentage reaching 46.14%. This is because most of the area is the lower slope of denudational volcanic cones and river cliffs. Medium and high hazards with the lowest area are in East Bogor Subdistrict, where the dominance of the area is the volvio volcanic plain covering an area of 70.41% of the total area.
