The Langtang Lirung collapse wasn't a glacial lake flood, and that changes which mountains Nepal has to watch

Climate & Environment A week of satellite, seismic and drone analysis has settled one thing — no lake burst above Rasuwa. The next one may not come from a lake either. By Laxman Rawal · Aug 31, 2026 Read the full story

No glacial lake burst above Rasuwa on 26 August. That is the firmest conclusion from a week of satellite, seismic and drone analysis, and it matters more than it sounds. Nepal's flood-warning apparatus is built almost entirely around lakes. This disaster did… Travel Himalaya Nepal · News

Which valleys carry the same signature

The honest answer is that Nepal does not know, because nobody has counted. India has started. A basin-scale inventory in npj Natural Hazards this year mapped 219 hanging glaciers in the Alaknanda basin of the Garhwal Himalaya alone — 71.7 &plusmn; 3.5… Travel Himalaya Nepal · News

The warning that existed and was never delivered

A security camera at Gyirong Port is stamped 10:59:53 China time — 08:44 NPT — roughly seven minutes after the seismic signal, about 14 km downstream. Seven minutes is not nothing. It is the difference between a school bell and a body count. The signal… Travel Himalaya Nepal · News
