Darkness, rising mud, and total silence. That was the reality for Sanjay Sah and Kabir Maharjan when a catastrophic flash flood sealed them inside the Upper Trishuli 3A hydropower station in Nepal. Most people assume that being buried under a mountain for over a week leaves zero chance of survival. They're wrong.
When a massive glacier collapse near the Nepal-Tibet border triggered a wall of mud and water on August 26, it killed more than 1,300 people and altered the local geography entirely. The entrance to the hydropower tunnel vanished completely beneath massive piles of debris. Inside, about 170 meters deep, Sah and Maharjan found themselves cut off from the world.
The Anatomy of an Underground Prison
Survival stories like this rely entirely on physics and sheer willpower. Sah, a 30-year-old mechanical foreman, stayed behind when the disaster struck because he felt responsible for helping other workers escape the control room. That choice trapped him.
The two men ended up sharing an accidental air pocket roughly 170 meters inside the tunnel structure. Water pooled around them, turning the floor into a thick slush. Maharjan drifted in and out of consciousness, sipping the muddy water around him to stay alive. Meanwhile, Sah kept his sanity intact by continuously chanting Hindu mantras in pitch blackness.
Days turned into a week. Above ground, families lost hope. Rescuers faced an unprecedented challenge because the landscape looked so different that they couldn't even find where the tunnel entrances used to be.
How Rescuers Cracked the Mountain
Finding the trapped men required an extraordinary mix of old-school grit and modern digital coordination. Rescuers had to use satellite imagery, helicopter footage, and old topographic maps just to figure out where the buried tunnel mouth was located.
Engineers relied on a rapidly expanded WhatsApp group to share blueprints, powerhouse layouts, and missing worker phone numbers in real-time. Once heavy excavators cleared away boulders the size of cars from the entrance, teams had to drill cautiously. They used carefully managed controlled explosions, risking stability to push deeper without collapsing the cavity where survivors might still breathe.
On the tenth day, heavy equipment operators cutting their engines heard a faint noise. They shouted into the void. A weak response came back from the dark: a single word confirming human presence.
Rescuers broke through the final meters of mud to find Sah and Maharjan. Sah couldn't stand and had to be carried out on a rescuer's back, his face caked in dry mud, while Maharjan was moved out on a stretcher. Their recovery from deep underground proved that even against devastating odds, pockets of air and human resilience can rewrite the limits of survival.
