On August 26, 2026, shortly after 8:37 a.m., a slab of rock and glacier ice broke off the north face of Langtang Lirung, a 7,227-meter peak in Nepal's Rasuwa district near the Chinese border. The front of the flow it became averaged about 190 kilometers per hour over its first 22 kilometers. Nepal's flood forecasting division sent text alerts to some 679,000 people 38 minutes after the collapse; Timure, the settlement nearest the border, had less warning time than anywhere downstream and went under. By September 12, 1,429 people were confirmed dead across Nepal and Tibet and 5,649 were still missing. Nepal's national planning commission and its disaster authority put the rebuilding bill at US$4.73 billion.
