In the wake of devastating flash floods in Nepal, rescue teams are racing against time to reach over 900 hydropower workers believed to be trapped in underground tunnels across multiple power projects. The disaster, which struck last week, has resulted in a death toll nearing 940 in Nepal, with additional casualties reported in Tibet. Thousands of people remain missing on both sides of the border, intensifying the urgency of the rescue efforts.
Approximately 500 of the missing workers are thought to be trapped within tunnels at hydropower plants located in the severely affected districts of Rasuwa and Nuwakot. The rescue teams face increasing challenges as the oxygen levels within these tunnels continue to drop, reducing the likelihood of finding survivors. Workers who escaped the initial flooding have recounted that many of their coworkers were still inside when the disaster hit, highlighting the dire situation.
Efforts to reach those trapped are being complicated by a combination of destroyed infrastructure, such as bridges, and unpredictable river conditions. The rugged terrain has necessitated a heavy reliance on helicopters, while international aid in the form of temporary bridge materials is being provided to restore access routes. The immense amount of debris is obstructing tunnel entrances, prompting some rescue operations to resort to blasting to gain entry. The floods have significantly impaired a large portion of Nepal’s power generation capabilities.
Inside the tunnels, rescuers are contending with extremely challenging conditions, including mud reaching chest height and poor visibility. Despite these grim circumstances, there remains cautious optimism that some workers may have reached safe zones within the tunnel systems. The disaster has affected tens of thousands of people, obliterating whole communities and sparking renewed concerns about the impact of climate change on glacial and mountainous regions. Nepalese authorities have labeled the flooding as an unprecedented natural calamity, with tens of thousands of security forces and volunteers mobilized to assist in the relief efforts.
International assistance has been swift, with specialized rescue teams, financial aid, and technical support arriving from neighboring countries to tackle the magnitude of the crisis. Amidst the devastation, there have been moments of hope, such as the rescue of a young child found alive in the mud. Additionally, the disaster has raised issues regarding the exchange of glacier and water-level data between neighboring nations, with officials expressing concern that insufficient information sharing could hinder future disaster preparedness across the region.
