Abstract
In this study, landslide susceptibility analysis were undertaken in the Astore region, Pakistan. The Geographical Information System (GIS) and Remote Sensing (RS) techniques were used along with the analytical hierarchy process (AHP) to find out the landslide susceptibility of the region. The Astore, lying in the Himalayan mountains, experiences frequent landslides due to several triggering factors. Factors including slope, lithology, aspect, topographic wetness index (TWI), plan curvature, stream power index (SPI), distance from drainage, land use land cover (LULC) and soil were used. Each factor was processed in the GIS environment and weighted through the AHP technique. AHP weights were derived with a consistency ratio of 0.06. Finally, the five zones, very low, low, moderate, high, and very high are respectively covering 20.5% (28.98 km2), 33.1% (46.78 km2), 30.6% (43.26 km2), 10.8% (15.28 km2), and 4.9% (6.92 km2). Slope, lithology and LULC were the most important factors in triggering landslides.

Although studeis on landslide are need of time, but a lot of reserchers are focusing on landslide. a number of other field like rare earth minerals in GB, geophysical studeis ofdifferent subsurface deposits are laking in GB.
you are absolutely right sir that landslide studies are crucial given the region’s vulnerability, but your point is well taken—there is also a pressing need to diversify research in Gilgit-Baltistan. Areas like rare earth mineral exploration, geophysical investigations of subsurface deposits, and other untapped resources remain underexplored.
