The cascading disaster was triggered by the collapse of a massive glacier in Nepal’s Langtang national park at about 8:40am
A glacier broke apart. An ice and rock avalanche followed. Then came an earthquake, before a landslide triggered devastating floods that tore through kilometres of valley. This is what happened along the Nepal-China border, where rescue teams are still trying to recover survivors 48 hours after the catastrophe. FRANCE 24 breaks down the chain of events and the scientific explanations behind the disaster.
The evidence now points to a large collapse of ice and rock high in the Himalayas near Langtang Lirung, rather than heavy rainfall.

Long before trucks climbed Bhote Koshi valley, mule caravans carried rice and other grain from Nepal north to Gyirong, where traders exchanged them for Tibetan salt and wool. Salt, highly valued in Nepal’s middle hills, travelled farther south towards India. Newar merchant communities also settled in Tibetan trading towns. Nepalese troops later used the route during invasions of Tibet in 1788 and 1791 before Chinese and Tibetan forces counter-attacked in 1792.
