Abstract

Physical and hydrometeorological properties of Karangkobar Catchment combine with poor land management cause landslide is commonly occurred in Karangkobar Catchment. This research is aiming to proof the role of land cover change to landslide susceptibility in Karangkobar Catchment. We use LULC change detection and landslide susceptibility analysis in this research. Main data use in this research is Landsat imagery from 1990 to 2018. LULC change detection is done using supervised classification to divide the land cover in the research area. Landslide susceptibility analysis was done using overlaying parameters then the landslide susceptibility analysis divides into 3 classes of susceptibility. Land cover in the research area tends to shift from agroforestry land to agricultural area or built up land. This affected the landslide susceptibility, it shifted from medium in 1990 to high susceptibility for almost 3 decades later. This analysis is proof of the role of the land cover change to landslide susceptibility in the research area. Furthermore, this phenomenon should be a warning to maintaining the land better and reducing the landslide susceptibility in the future. © Published under licence by IOP Publishing Ltd.
