Scientists Investigate Likely Causes Of The Nepal-Tibet Flash Floods

Scientists investigating the catastrophic floods that swept across the Nepal-China border at about 9am Nepal local time on Wednesday 26th of August 2026, say the disaster was triggered by a massive collapse of an ice rock high in the Himalayas, rather than by an earthquake as initially suspected.

The collapse sent a powerful mixture of water, mud, boulders and debris into the Lhende Khola, a tributary of the Bhote Koshi River. This produced a sudden flood wave that devastated communities, roads, bridges and hydro-power infrastructure downstream.

Satellite imagery and preliminary scientific analysis indicate that a large section of a glacier broke away at an elevation of roughly 5,200 meters (17,000 feet) before plunging about 1,200 meters valley below.

Scientists are continuing to examine satellite imagery, seismic records, hydrological data, and field evidence, to determine precisely how the collapse unfolded.
