Following catastrophic Himalayan flooding on August 26, mechanical supervisor Kabir Maharjan and mechanical foreman Sanjay Shah were rescued alive on Friday after spending nine days trapped in an air-pocket inside the Trishuli 3A hydropower project tunnel in Nepal, amid a disaster that has killed over 1,300 people.
The Anatomy of a Himalayan Tsunami
When a massive glacier collapsed at the Langtang Lirung mountain roughly 25 miles upstream, it unleashed a wall of mud, rock, and water. According to accounts shared by officials with Reuters, the debris stream flattened mountain settlements and rapidly overwhelmed a network of 12 hydropower projects operating across the region.
Inside the Trishuli 3A hydropower station, control room monitors began going blank one by one. Electricity department officials in Kathmandu watched the control panels fail like dominoes. Suraj Dahal, an engineer at the Nepal Electricity Authority who helped lead the search, noted that initial assumptions of normal seasonal flooding were quickly shattered as the true scale of the disaster unfolded.
Because the station manager was abroad, warning calls to the roughly 40 workers estimated to be inside were delayed by crucial minutes. By the time the final evacuation order was issued at 9:15 a.m., escape routes were already cut off by the surging wall of water. While some workers attempted to flee on foot, engineering reviews later revealed that an escape ladder existed inside the tunnels—a potential exit that could have saved two-thirds of those inside had they known its exact location.
Survival in Total Darkness
Facing rising waters and choking debris, Kabir Maharjan and Sanjay Shah found refuge in a shorter cable-duct tunnel that sloped upward, remaining less exposed to the main flood surge. According to lawmaker Shri Ram Neupane, a veteran tunnel engineer who helped lead the rescue operation, the two men took shelter just 160 meters from the exit at the edge of the tunnel.
For nine days, that trapped air pocket served as their prison. Maharjan later recounted drifting in and out of consciousness in a pool of muddy water in complete darkness. Outside, rescue teams faced monumental hurdles. Teams aided by international experts repeatedly hit walls of hard-packed debris while searching through multiple hydropower tunnels where more than 100 workers were initially feared trapped.
Hope flickered and nearly died in the days leading up to the breakthrough. Some Nepali families searching for missing loved ones had already begun holding symbolic funerals as the timeline stretched past a week. But on Friday, operations at Trishuli 3A shifted dramatically.
Inside the Rescue Operation
Arnold Dix, president of the International Tunnelling and Underground Space Association who supported the operation remotely, described the mission as returning to “miracle country” following a grueling week of continuous heartache. Hours before the extraction, search teams detected a faint human response from deep within the blocked passageway. Workers heard a faint voice responding with “hunchha,” meaning yes or OK in Nepali.
Rescue crews immediately called back into the opening, urging the trapped men to hold on. Having dug through 50 to 60 meters of dense debris blocking the tunnel, teams broke through to find the two men alive. Dramatic footage released by the energy ministry showed rescuers cheering as one man emerged through a muddy opening, while Kabir Maharjan was carried out by emergency workers.
Home Minister Sudan Gurung formally identified the survivors as 45-year-old Kabir Maharjan and 30-year-old Sanjay Shah. Both men were immediately transferred for medical treatment. When Maharjan finally awoke at the hospital, his disorientation was absolute; still recovering from his ordeal, he asked his wife why she had not provided him with a bed sooner.
Transnational Ripples and Infrastructure Vulnerability
| Metric / Detail | Recorded Figure / Status |
|---|---|
| Disaster Date | August 26 |
| Primary Trigger | Glacial and rock collapse at Langtang Lirung mountain |
| Estimated Casualties | Over 1,300 dead across Nepal and Tibet |
| Damaged Hydropower Projects | At least 12 projects smashed or severely impacted |
| Tunnel Survival Duration | 9 days (Kabir Maharjan and Sanjay Shah) |
| Rescue Site | Trishuli 3A Hydropower Station |
Foreign Minister Shisir Khanal characterized the gigantic wave as a “Himalayan tsunami,” underscoring the severe vulnerability of regional infrastructure to climate-driven glacial events. With at least 12 major hydropower installations smashed across the mountain districts, the disaster has severely impacted regional energy generation grids and supply chains shared across borders.
As search and rescue operations continue for remaining workers accounted for in government registries, the survival of Maharjan and Shah offers a singular moment of relief amid a national tragedy. Yet, the broader geopolitical and economic ramifications remain stark. Transnational energy planning in the Himalayas now faces urgent re-evaluations regarding climate resilience, early-warning sensor placement, and structural escape route protocols for underground facilities.
