The 11 October 2026 landslide and debris flow/flood on the Budhi Gandaki River in Gorkha district, Nepal
Information is emerging about this major event in Nepal. Helicopter video suggests that it was initiated by a very dynamic landslide – possibly a rock avalanche? On 11 October 2026, yet another major debris flow/flood occurred in Nepal, sweeping down the Budhi Gandaki River in Gorkha district. This has caused substantial damage, although not on […]
On 11 October 2026, a major landslide and subsequent debris flow/flood occurred on the Budhi Gandaki River in Nepal's Gorkha district. The event, which took place at 04:22 local time, likely originated as a rock avalanche or dynamic landslide in the Chumchet area, situated at coordinates [28.4755, 84.9644].
Seismic data from Kristen Cook indicated the landslide at an early stage, followed by a breach of the landslide dam around 06:00. This resulted in the debris flow/flood that quickly descended downstream. Despite the warning dissemination, the event caused significant damage, though it was not as severe as the 26 August 2026 Langtang Lirung event.
Five people are believed to have lost their lives, while houses, roads, and bridges suffered extensive damage. The debris flow also impacted the Budhi Gandaki hydropower project site, with the video capturing the destruction of a 225-meter high dam. This incident underscores the ongoing challenges faced in Himalayan valleys due to geological hazards. As satellite and aerial imagery becomes available in the coming days, a more comprehensive analysis of the event will be possible.
