Longsor es-batuan dari gletser di Himalaya memicu banjir bandang di perbatasan Nepal-China pada 26 Agustus 2026, menewaskan ratusan orang. Otoritas penanggulangan bencana Nepal (NDRRMA) mencatat 165 tewas dan 826 hilang per 27 Agustus, sementara peta dampak ERCC/DG ECHO menyebut 359 tewas dan 910 hilang di sisi Nepal, serta 3 tewas dan 550 hilang di Gyirong, Tibet, menurut CCTV. Longsor menyumbat Sungai Lhende Khola, anak sungai Bhotekoshi, lalu jebol; muka air Sungai Trisuli naik sekitar sembilan meter dalam 30 menit (ICIMOD). Sebanyak 579 wisatawan belum ditemukan, termasuk 466 warga asing dari 28 negara: 133 peziarah India menuju Gunung Kailash, 47 warga Amerika Serikat, 34 Australia, 33 Inggris, dan 24 Kanada. Sedikitnya 40 kilometer jalan dan 80 jembatan rusak (ERCC). Wilayah yang sama dilanda banjir pada Agustus 2025, dan Lhende Khola kini banjir dua kali dalam 14 bulan. ICIMOD menilai “Himalaya yang memanas” memperbesar risiko longsor es dan banjir glasial di jalur pendakian.

An ice-rock avalanche from a Himalayan glacier triggered flash floods along the Nepal-China border on 26 August 2026, killing hundreds. Nepal's disaster agency (NDRRMA) recorded 165 dead and 826 missing as of 27 August, while ERCC/DG ECHO impact mapping reported 359 dead and 910 missing on the Nepal side, with 3 dead and 550 missing in Gyirong, Tibet, according to CCTV. The landslide dammed the Lhende Khola, a tributary of the Bhotekoshi, then breached; water levels on the Trisuli River rose about nine metres in 30 minutes (ICIMOD). Some 579 tourists remain unaccounted for, including 466 foreigners from 28 countries: 133 Indian pilgrims bound for Mount Kailash, 47 US citizens, 34 Australians, 33 Britons and 24 Canadians. At least 40 kilometres of road and 80 bridges were damaged (ERCC). The same area flooded in August 2025, and the Lhende Khola has now flooded twice in 14 months. ICIMOD says a “warming Himalaya” increases the risk of ice avalanches and glacial floods on trekking routes.
