Rescue operations are ongoing in Nepal for hydropower workers trapped following a devastating glacier collapse and subsequent flood that has claimed over 1,000 lives. A new report indicates that the disaster could have been averted or its impact lessened with better early warning systems.
Scientists observed signs of increasing instability around the glacier in the days leading up to the event. Satellite imagery revealed accelerated glacier surface movement, a change in meltwater color to brown, and the development of a crack in the surrounding rock. These indicators, noted by experts from the Asian Mountain Academic Alliance, the Stimson Centre, and China's Institute of Mountain Hazards and Environment, suggested a deteriorating mountainside.
The avalanche itself moved with extreme speed, making conventional warnings ineffective for those in its immediate path. However, for areas downstream where the floodwaters took 10 minutes or longer to arrive, a comprehensive warning system might have saved a significant number of lives, according to the scientists.
Rescue Efforts Intensify
Specialists from China, India, and Nepal are currently utilizing excavators and heavy machinery to clear debris from hydropower projects. The goal is to reach workers who remain trapped at several sites along the Trishuli River. "There are probably still some survivors inside. I would be happy if they were rescued quickly," said one worker who described being chased by the river water for 20 minutes. "I know many people who are still trapped there."
Rescuers are working to extract survivors from tunnels, with efforts including pumping oxygen to aid those trapped underground. Machinery is being used to clear the mud and debris that inundated the hydropower sites. In Gyirong, Tibet, CCTV footage captured people fleeing as mud and water surged through the area, destroying buildings.
