A glacier-triggered flash flood tore through Nepal’s northern Rasuwa district and across the border into Tibet on the morning of Wednesday, August 26, 2026, killing dozens of people and leaving more than 400 people — most of them foreign tourists — unaccounted for^[1].

Key Facts

• The Bhote Koshi River surged around 9 a.m. local time, tearing through the Rasuwa district and spreading into the neighboring Nuwakot and Dhading districts before crossing into Gyirong County on the Tibet side of the border^[2].
• At least 98 people were confirmed killed across Nepal and China, with more than 400 still listed as missing — among them 341 foreign nationals, including 47 Americans by one count and 33 by another as the toll was still being confirmed^[3][2].
• Villages, roads, bridges, and hydropower infrastructure along the river were destroyed; NBC News said videos it verified showed bridges cracking apart and being swept away by mud- and debris-filled floodwater^[4].
• Nepal’s government asked India and China for help with rescue operations, and access to some of the hardest-hit areas, including Syabrubesi and Timure, was hampered by damaged roads^[2].

What Caused It

Accounts of the immediate trigger differ slightly by source, reflecting how fast this story is still developing. Nepal’s International Centre for Integrated Mountain Development (ICIMOD) identified an ice-and-rock avalanche off a glacier as the trigger: the avalanche blocked the Lhende Khola, a tributary of the Bhote Koshi, before the blockage gave way and sent a sudden surge downstream — the second time that tributary has flooded in fourteen months^[1]. Nepal’s foreign minister, Shishir Khanal, separately said an earthquake-triggered landslide blocked the Bhote Koshi itself^[2] — a magnitude 4.4 earthquake struck roughly 60 miles north of Kathmandu around the same time^[1].

Either way, the event fits a well-documented and worsening regional hazard pattern. Peer-reviewed research on the Himalaya-Karakoram region has found that ice avalanches, rockfall, and landslides are the dominant trigger behind most glacial lake outburst floods (GLOFs) recorded in the area, and that Himalayan glacial lakes have been growing as the region warms^[5]. The American Geophysical Union’s Eos.org has separately reported that millions of people living downstream of Himalayan glacial lakes are at risk from this exact kind of sudden-outburst flooding^[6].

Footage From the Ground

Video verified by Indian financial-news broadcaster NDTV Profit shows the flood carrying away a bridge and houses near Trishuli Bazar, close to the Rasuwa district where the flood first surged^[7]:

NBC News has published its own verified U.S.-outlet footage of a bridge being destroyed by the floodwater, part of its broader coverage of the disaster^[4].

What’s Still Unconfirmed

The death toll and missing-persons count were still moving between outlets as of this writing, which is typical in the first day of a disaster of this scale — figures above are attributed to the specific outlet and time they were reported. The exact nationality breakdown of the missing, and whether the Aug. 26 trigger was primarily the glacier avalanche described by ICIMOD or the earthquake-triggered landslide described by Nepal’s foreign ministry, had not been reconciled by any single authoritative source at publication time.

Rescue crews remain focused on reaching cut-off villages as the toll is confirmed — check back for updates as Nepali and Chinese authorities finalize the numbers.
