Rescue teams in Nepal saved two men from the Upper Trishuli-3A Hydropower Project tunnel on Friday. The survivors were trapped for nine days following catastrophic floods that began on August 26.
Sanjay Sah and Kabir Maharjan: The First Survivors of the Upper Trishuli-3A Tunnel
The rescue of mechanical foreman Sanjay Sah and mechanical supervisor Kabir Maharjan marks a pivotal moment in a desperate search operation. According to the report, the Nepal Army and local authorities located the men after hearing voices echoing from the depths of the Upper Trishuli-3A Hydropower Project site.. The extraction was perilous, with one survivor found in critical condition, covered in mud, and requiring an airlift to a specialized hospital in Kathmandu.
The 500 Workers Trapped Across 12 Hydropower Projects
The scale of the disaster extends far beyond these two individuals. Data provided by the Independent Power Producers Association of Nepal indicates that at least 557 workers are missing from the Upper Trishuli-3A project alone, with roughly 115 of them believed to be entombed within the tunnel system. On a broader regional scale, local authorities estimate that approximately 900 workers are missing across 12 different hydropower projects, with about 500 of those individuals likely trapped underground.
This mass disappearance underscores the extreme risks associated with large-scale infrastructure projects in the Himalayas. The concentration of workers in subterrnean environments during a climate event creates a rescue nightmare, as the sheer volume of missing personnel overwhelms available resources.
A Glacier Collapse and the Bhotekoshi River Surge
The catastrophe was triggered on August 26 when the Bhotekoshi River overflowed its banks in a violent surge. As the report says, initial assessments suggest the disaster may have been caused by a massive glacier collapse, which sent torrents of water and debris crashing down the mountainsides. This event highlights the increasing vulnerability of mountainous regions to climate-driven disasters, where sudden glacial lake outburst floods can obliterate entire villages and infrastructure in minutes.
The impact was not confined to Nepal. Chinese authorities reported that the same disaster claimed 21 lives and left 541 people missing on the Tibet side of the border. With a total death toll in Nepal reaching at least 1,259 and over 5,000 people missing,the event stands as one of the region's most lethal recent environmental crises.
Who Else Remains Alive in the Silt-Filled Tunnels?
While the rescue of Sah and Maharjan provides hope , significant questions remain regarding the fate of the hundreds still missing.. One of the survivors reportedly told rescuers that other colleagues are still alive inside the tunnel, but the identity and exact location of these individuals remain unknown. It is currently unclear how many of the 115 workers trapped in the Upper Trishuli-3A tunnels are in reachable areas or if they have access to air pockets.
The technical challenge is immense.. Rescuers must navigate unstable tunnels filled with silt and water, facing a high risk of further collapses. The coordination between the Nepal Army and civil engineers is now the primary focus as they attempt to stabilize the structures to allow for deeper entry.
