Abstract

The study focused on identifying the causes and landslide-prone areas in Abbottabad District of Northern Pakistan. Remote sensing data, including NASA's Shuttle Radar Topographic Mission's (SRTM) Digital Elevation Model (DEM) and Landslide-8 imagery, were used in combination with geographic indices to identify the factors of landslides, such as slope, aspect, elevation, vegetation cover, hydrology, SAVI, and land cover change. The weighted overlay technique was used to assign weights to map layers and find the risk zones in the study area. The study revealed that the region is at risk of landslides due to high rock, sloppy areas, and built-up expansion. The major cluster of landslide risk is in the western and southern parts of the region, which are also more populated. The results and landslide susceptibility maps can be used to better understand the existence of landslides and for mitigation purposes, but field surveys are necessary for better predictions. Overall, the study provides valuable information for relevant authorities to prioritize landslide mitigation efforts in the region.
