Nepal Flash Flood explained: it was not an earthquake. A glacier collapse triggered the Rasuwa flood โ full chain of events, with satellite evidence.
On 26 August 2026, a catastrophic flash flood tore through the Rasuwa
and Nuwakot districts of Nepal, along the NepalโTibet border. The most
surprising detail: there was no unusual rainfall upstream. So where did
the water come from?
USGS initially reported the event as a magnitude 4.4 earthquake, then
revised its assessment entirely โ no earthquake had occurred. The
seismic signal came from a glacial collapse and debris flow, later
recorded as a magnitude 5.2 landslide.
