Future glacial lakes in High Mountain Asia: an inventory and assessment of hazard potential from surrounding slopes

Abstract Bedrock overdeepenings exposed by continued glacial retreat can store precipitation and meltwater, potentially leading to the formation of new proglacial lakes. These lakes may pose threats lake outburst floods (GLOFs) in high mountain areas, particularly if form geomorphological setups prone triggering events such as landslides or moraine collapses. We present first complete inventory for future High Mountain Asia computing subglacial bedrock ~100 000 glaciers estimating overdeepening area, volume impact hazard larger potential detect 25 285 than 10 4 m 2 with a 99.1 ± 28.6 km 3 covering an area 2683 773.8 . For 2700 5 , we assess predisposition mass-movement impacts that could trigger GLOF material detaching from surrounding slopes. Our findings indicate shift southwestern Himalayan region toward Karakoram. The results this study be used anticipating emerging potentials connected basis further studies at suspected hotspots.
