With this dataset, we present the first inventory of subglacial overdeepenings indicating possible locations of future glacial lakes for the entire region of High Mountain Asia. We include an assessment of the hazard of mass movement impacts for each lake which, combined with the lake volume, gives a first-order impression of the potential glacial lake outburst flood (GLOF) hazard at a given location.
This dataset can be used for anticipating emerging threats and potentials connected to glacial lakes and as a basis for further studies at suspected GLOF hazard hotspots.
The related study is part of the GLAMoR project (Future Glacial Lakes in High Mountain Asia - Modeling and Risk Analysis) at the Geography Department of Humboldt-Universität zu Berlin. The results of the study were published in the Journal of Glaciology:
