Abstract (Abstrak)
Landslides have taken a significant role in the evolution of landscapes, are present almost everywhere, and serve as one of the catastrophic subjects of frequent natural disasters. The statistical-spatial modeling based on ethics of care in this era has become an advanced tool for assessing landslide hazards. The Bonehau sub-watershed shows a hydrogeomorphology that is identic to the occurrence of landslides. Moreover, 2.47% forested land converted annually supports the initiation and reactivation of landslide events. 2,468 landslide events detected in Google Earth imagery served as the basis for assessing vulnerability, hazard, and risk of landslides. The causative factor discrimination in frequency ratio (FR) shows that lithological factors, LCC, and slopes are the primary causes of landslides. The LSM was then constructed using a logistic regression model (LR). The ROC curve in the model is more inclined towards the sensitivity axis with AUC success and predictive of 0.732 and 0.674, respectively.
Keywords : landslide susceptibility map, landslide inventory, frequency ratio, logistic regression, ROC Curve, Bonehau Sub Watershed
