Following the publication in Science on the devastating 3 October 2023 South Lhonak glacial lake outburst flood (GLOF) in Sikkim, India, EClim member Christian Huggel shares key insights on LinkedIn into the magnitude and implications of the disaster.
The event was triggered by a massive landslide of frozen moraine into the lake, unleashing 50 million m³ of water and mobilizing an additional 270 million m³ of sediment. The cascading flood traveled over 300 km downstream, reaching Bangladesh and leaving a trail of destruction:
- 55 fatalities, 74 missing, and over 25,000 buildings affected
- Collapse of the 1200 MW Teesta-III hydropower dam and severe damage to other infrastructure
Christian underscores the interdisciplinary effort required to understand such complex events and calls for greater investment in risk assessments, early warning systems, and land-use planning. He also links this disaster to broader climate accountability, citing its relevance for ongoing climate litigation like the Saúl Lliuya vs RWE case in Peru, in which he serves as an expert.
