Identification and GIS Analysis of Disasters Occuring in Landslide Prone Areas of Pakistan

Abstract

The north east area of Pakistan is characterized as highly prone to landslide hazard. To monitor such vast areas physically where there is high vulnerability of the hazard is very difficult. The purpose of this study was to identify the potentially dangerous landslides to downward settlements in GIS environment by utilizing remote sensing techniques. The study was conducted in north east areas of Pakistan where there are several human settlements which are endangered due to landslide hazard. The sudden slide of highly unstable mass adjoined with receding rocks occurs because of seismic shocks. The DEM is utilized to detect the flow course of landslides involving slope, elevation and orientation of the mountains. The study results show that settlements in north east of Pakistan are found more threatened in comparison with east region. Keeping in view the frequent land sliding activity in the region of study, the habitat is facing potential danger. The results of the study provide a platform for establishment of an early warning and monitoring system..

Application of frequency ratio, information value, and weights-of-evidence models and their comparison in landslide susceptibility mapping in Murree region, Sub-Himalayas

“…LSM along China Pakistan Economic Corridor (CPEC) was performed to identify sensitive zones of landslides and to mitigate its impacts regarding socioeconomic development (Ali et al 2018). LSM of eastern zone of Pakistan was generated in 2019 using geospatial techniques to identify landslide prone regions (Gilany 2019). All causative factors have signi cant association with landslide hazards but the most important factor in causing landslides is soil erosion in the area which has been mostly ignored by researchers in Pakistan.…”
