Nepal's Himalaya Disaster: Why It Happened Twice

Nepal is still recovering from what may be the largest rock-ice avalanche ever recorded. On August 26th, 2026, a massive collapse near Langtang Lirung sent a wall of debris down the Trishuli river system, destroying communities across Rasuwa, Nuwakot, Dhading, Gorkha, and Tanahun, and crossing the border to destroy the Gyirong port crossing into Tibet. As of October, Nepal's confirmed death toll stands at 1,451, with 5,745 still missing - though UN figures also show 13,742 people rescued alive. This video explains the science behind the collapse, why this isn't the first time this exact valley has seen a disaster like this, why Nepal's flood-monitoring stations couldn't warn people in time, why one major hydropower plant was destroyed in the exact same spot it had already failed before, and how the global humanitarian response has unfolded since. Illustrations in this video are AI-generated editorial/conceptual art - maps, data graphics, and symbolic illustrations - not real footage of the events discussed. Given the scale of loss of life involved, all imagery is kept at the level of abstract maps, charts, and icons, out of respect for those affected.
