A wall of ice, rock and water.
On the morning of Wednesday 26 August 2026, a large section of glacier and rock broke away high above the Lhende river in Tibet, damming the river as it fell. When that debris dam gave way shortly after, the surge cascaded down through Rasuwa, Nuwakot and Dhading along the Trishuli river, tearing through the settlements along its banks. The debris also formed barrier lakes that continued to threaten further flooding in the days that followed, as water built up behind them.
At least 1,355 people have died and nearly 5,000 remain missing in Nepal, with an additional 43 dead and 519 missing across the border in Tibet. The United Nations estimates that at least 17,000 children have been affected in Rasuwa, Nuwakot and Dhading alone. Roads, bridges, water systems and telecommunications have been badly damaged, and many of the affected communities are still difficult to reach.
