Nepal Could Be Hit by Another Deadly Flood — Here's Why
Nepal Could Be Hit by Another Deadly Flood — Here's Why
Nepal has just been struck by a devastating glacier collapse and flash flood, but the danger may not be over. A massive collapse near Langtang Lirung, close to the Nepal-China border, sent rock, ice, mud, and water rushing downstream and devastated communities in Nepal and Tibet.
But the disaster created another potential threat: temporary glacial lakes and natural dams formed by massive amounts of rock and debris blocking the river. If an unstable debris dam suddenly fails, it could trigger another flash flood or glacial lake outburst flood (GLOF) downstream.
In this video, we explain what happened during the Nepal flood disaster, how the glacier collapse triggered the first flood, how the new lake formed, why authorities are monitoring it, and why another flood remains a concern.
We also look at Langtang Lirung, Chhochen Khola, the Trishuli River, Tibet, the Nepal-China border, glacial lakes, landslides, glacier instability, flash floods, GLOF risks, and the growing danger of Himalayan natural disasters.
Could Nepal face another deadly flood? What happens if the natural dam breaks? And why can a single glacier collapse trigger a chain reaction of floods, landslides, and new glacial lakes?
The Himalayas are changing rapidly, and Nepal's communities, rivers, roads, and hydropower infrastructure remain highly exposed to these hazards.
