Glacier Collapse Triggers Deadly Flash Floods on Nepal–Tibet Border

Overview

• A sudden collapse of ice, rock and sediment into the Lhende Khola produced fast-moving floods on Wednesday that swept through villages in Nepal and the Gyirong border area in Tibet.
• Authorities now report at least 353 people killed and more than 1,300 unaccounted for as rescue teams continue to search ravaged valleys and washed-out settlements.
• Nepalese and Chinese forces have mounted large-scale, cross-border search-and-rescue operations with helicopters and troops while international agencies and neighbouring governments offer assistance.
• The floods destroyed roads, bridges and hydropower facilities, damaging roughly 430 megawatts of generation capacity and blocking access routes that are slowing relief and recovery work.
• Scientific agencies revised early readings to show the seismic signal was caused by the glacier collapse itself, and experts warn that the upstream blockage could suddenly release more water and debris downstream.
