On the morning of August 26, a section of mountain near Langtang Lirung peak in Nepal suddenly collapsed.
A huge mass of rock, ice and debris plunged roughly 1,200 metres into the valley below, producing a hugely destructive flood on the Lhende Khola river. The flow travelled almost 100 kilometres downstream, washing villages and bridges away. Almost 1,000 people died and thousands more are still missing across the Nepal-China border.
