“…Furthermore, the area is highly susceptible to snow avalanches and glacial hazards. Several disastrous events can be noted from history such as the debris flow on Jul 27, 2000, which destroyed 124 houses, and a gigantic glacial flow on Apr 7, 2012 that took the lives of 139 people along with infrastructure and livestock damages (Gilany and Iqbal 2017).…”

“…In exploring the hazards prevalent in our study area, snow avalanches emerge as a significant concern (Hewitt 1988;Hewitt et al 2011;Hasson et al 2014;Gilany and Iqbal 2017), demanding a detailed evaluation (Shroder et al 2011). We adopted a thorough approach, considering twelve factors like slope, distance to fault, lithology, and others to create a Snow Avalanche Susceptibility Index .…”

The rapid deglaciation in the Upper Indus Basin (UIB) significantly impacts local landscapes, watersheds, and basin-wide hydrology. While creating new opportunities, such as emerging landscapes and hydrological changes, deglaciation simultaneously heightens the risk of glacio-hydrological hazards in adjacent and downstream regions. With limited available land for agriculture and settlements, communities around glaciers expand human activities toward newly formed floodplains and deglaciating valleys, necessitating a comprehensive understanding of associated risks and vulnerabilities. This study employs Geographical Information System (GIS) and Remote Sensing products for a multicriteria hazards susceptibility assessment in the Shigar Valley, located in the downstream of major Himalayan glaciers – the Baltoro (63 km) and Biafo (67 km) glaciers. The research reveals that 28.3% of the valley is highly susceptible to multiple hazards, emphasizing the urgency of informed decision-making in the region. Only 0.03% area lies in the very low susceptible category, 9.7% in the low susceptible, 60.6% in the moderately susceptible, and 1.04% in the very highly susceptible categories. These findings highlight the need for proactive measures, adaptive strategies, and sustainable development in the Shigar Valley to mitigate the escalating risks posed by deglaciation and changing hydrological patterns.

“…A hydro-meteorological perspective on the anomaly of glacier dynamics has originated the argument of heavy accumulation zones, thus disturbing the mass balance [6]. The natural stability and behavior of the glacier are very much dependent on slope, elevation, aspect, and geomorphology of the vicinity [7]. Glacier expansion is very much related to the elevation from mean sea level in the Karakoram region [8].…”

Glacial avalanche hazard poses threat to human lives and damage settlements / infrastructures in alpine glaciers mountainous regions. A gigantic ice plus rock avalanche destroyed Gyari military camp in Siachen sector on April 2012 and buried 139 personals. The study focuses on geospatial analysis and simulation of Shishper glacial avalanche of Hunza basin. To simulate the potential glacial avalanche hazard to Hassan Abad settlements, an empirical process based Glacier Avalanche Model; Rapid Access Mass Movement Simulation (RAMMS) is utilized. The model encompasses avalanche release area and height for the execution of simulation. The model output of Shishper glacial avalanche resulted; a max pressure of 450 Kpa, max velocity of 40 m/s, and the max flow height of 80m, while the resulted surge extent output was 2500m. The potential hazardous Shishper glacial avalanche remains a continuous hazard to Hassan Abad of Hunza valley including Karakoram Highway and Frontier Works Organization (FWO) camp. The study has resulted in identifying the Upper Indus Bain (UIB) being more prone to glacial avalanche hazards because of host factors in general and the anthropogenic factor in particular.
