Fig. 1. Map of the Indian state of Sikkim showing the location of the South Lhonak Lake and the two major settlements along the valley; Google Earth image showing the bird-eye view of (B) the tongue of the South Lhonak glacier and its associated proglacial lake; and (C) frontal moraine damming the South Lhonak Lake; (D-G) Landsat image showing the evolution of the lake as the glacier retreated from 1990 to 2019; (Hsingle bondI) Field photograph of the South Lhonak Lake showing the current glacier terminus, lateral moraines, and frontal part of the moraine (photo courtesy: Department of Science and Technology, Government of Sikkim).
Fig. 2. Schematic diagram showing (A) a proglacial lake system at present; (B) lake grows as the overdeepened glacier bed is exposed in the future by glacier retreat, further exposing it to potential mass movements that can enter the lake.
Fig. 3. South Lhonak glacier-lake system showing the extent of the present lake (SLL) and overdeepening (OVD); the topographic potential for mass movements is shown for the surrounding slopes; (B) avalanche source zone showing highly crevassed and hanging ice and/or rock (located ~930 m upstream of the current terminus).
Fig. 4. Inundation boundaries and (B) spatially distributed flow depth (Df) and flow velocity (Vf) at Chungthang of each predicted GLOF scenario.
Fig. 5. Evolution of the Chungthang town. The rapid growth of the infrastructure is seen after the establishment of the hydropower setup.
