Disclaimer: Before informing about this tragic incident, I offer my condolences to the victims and their loved ones.

At 8:37 on 26 August 2026 NST (Nepal Standard Time), flash floods swept through the Trishuli River across Nepal and Tibet following the landslide at Langtang Lirung Peak, washing away towns, power plants, and many buildings, including the Gyirong Port between China and Nepal, and leaving behind large amounts of debris.
But before we dive into what happened in this tragic incident, let’s get to what matters most. For the loved ones of the victims, I am sorry for your loss. There are some ways in which you can get help through the helplines and contact information provided in these links:

But know this: there are other helplines available to get help from, as these are not the only sources.
Moreover, it is important to understand what has happened in this tragedy, starting with visual evidence.
Satellite Imagery from Landsat 9 on that day showed a hill of mud at Langtang Lirung Peak. In contrast, Sentinel 2’s imagery from two days before the disaster shows the white Glacier terminus of its grey peak, surrounded by rugged terrain.
Along with that, CCTV footage on that day at 10:59 CST (Chinese Standard Time) shows people running away from Gyirong Port, as floods rush into the area, washing away the port, surrounding buildings, and vehicles such as buses, cars, and trucks, only to fill the valley with muddy water and debris.
The aftermath of this horrible tragedy is the loss of lives and connections, along with the loss of history flourishing at the roof of the earth.
Reports say that infrastructure, such as 40 bridges connecting the banks of the river, 25 roads connecting people across Nepal, and phone and power lines connecting people all around the world, has been destroyed.
Moreover, many civilians unfortunately have died because there was not enough distance and time to get away from the hurrying floodwaters. As of Sep 15 2026, according to The Hindu, the death toll is at a minimum of 1,399, followed by 5,170 missing civilians.
