The glacier collapse caused widespread destruction, including the loss of over 650 lives and displacement of 93,000 people. The hyper-concentrated slurry obliterated riverine ecosystems, destroyed critical infrastructure, and disrupted hydropower generation. Agricultural lands were smothered by sediment, altering soil conditions and causing long-term ecological degradation. The disaster also highlighted the vulnerability of transboundary infrastructure in the Himalayan region, with impacts felt across Nepal and neighbouring countries.
