“…There is an elevation boundary that makes the number of landslides reach the peak at that elevation boundary, whereupon the phenomenon of decreasing above that elevation boundary will occur. For example, the elevation boundary of the China-Pakistan Karakoram Highway is 2100 m [52]; along the Jinsha River Basin, the elevation boundary is 2000 m [13]. With increased altitude, due to human activity, river erosion, and rock weathering, the number of landslides is small and the degree of development is slow.…”

“…However, there are many exceptions. For example, along the China-Pakistan Karakoram Highway area, the rainfall range is 162-941 mm/a, with 84.3% of landslides occurring in areas in the semi-arid region (<400 mm/a) [52]; along the Sichuan-Tibet Railway Ya'an-Linzhi). No significant statistical relationship emerged between rainfall and landslide distribution [39].…”

“…For engineers and geologists, determining landslide susceptibility with limited data is a problem in the support of planners and governmental organizations. To undertake landslide detection and mapping, optical remote sensing can be integrated with InSAR technology, which can overcome these limitations 12 . A strong tool for landslide detection and mapping at a wide scale is the use of SAR interferometric techniques, which can also help with the development and updating of landslide inventory maps 13 .…”

“…Interferometric Synthetic Aperture Radar (InSAR) techniques have gained widespread acceptance and use as tools for landslide mapping and monitoring over recent years. Although different techniques of InSAR have been successfully used in mapping slope deformations associated like 14 estimated surface deformation areas detected by SBAS-InSAR 12 , 15 , applied D-InSAR method for land subsidence and landslide monitoring 16 18 , generated SqeeInSAR method to check the ground movement 19 , used Stanford Method for Persistent Scatterers (StaMPS) to assess the deformation in dense vegetation area 20 22 , tested PSInSAR approach to calculate the movement of landslide. PSInSAR is effective in automatic slow-moving landslide mapping based on the use of a spatial statistical approach, the identification of individual landslides and the delineation of generalized unstable areas, the redefinition of the limits of ancient landslides, the identification of landslides based on the multi-temporal comparison of SAR imagery and the identification of the terrain elements responsible for slope deformation is made easier by the combined use of optical imagery 23 .…”

“…There are already plethora of studies on earthquake and rainfall-triggered landslide inventories, as well as related landslide risk and hazard assessments, that have been carried out in the region, mainly in Pakistan (Dunning et al, 2007;Khattak et al, 2010;Ahmed and Rogers, 2015;Basharat et al, 2016;Khan et al, 2019;Imtiaz et al, 2022). In recent years, landslide-oriented research has been extended to the entire CPEC, especially for landslides along the KKH (Bacha et al, 2018;Rashid et al, 2020;Chang et al, 2021;Hussain et al, 2021;Maqsoom et al, 2022;Su et al, 2021). Hazard and risk assessments of some large-sized landslides were also carried out in this area, such as the Attabad landslide (Chen et al, 2017), where landslide dam breach and its hazards to the KKH project construction site downstream was discussed.…”
