Their flood videos went viral. They are still haunted by what they saw

On August 26, a catastrophic flood tore through towns along the Bhotekoshi corridor. The disaster began after a massive glacial collapse in the Lhende valley near the Nepal-China border. Rock, ice, and debris rushed into the river, turning it into a destructive torrent. The videos matter because they show the flood’s speed and force from close range.

Nabayug Shrestha filmed the river at Trishuli Bazar. His footage shows the water surging beneath a bridge before bursting through the channel in a towering spray. Bhimsen Thapa filmed from another bridge. His clips show people shouting, “Run! Run!” before the wave swept away fields and houses.

Shrestha posted his video on September 5, and it later passed one million views. Thapa and Shrestha survived, but their recordings remain painful reminders of the people, homes, and landscapes lost. The bridge they filmed from was also destroyed.

The two surviving filmmakers were Nabayug Shrestha, 34, and Bhimsen Thapa, 62. Their videos became rare visual evidence that the men behind the cameras escaped the disaster. Their survival, however, did not spare them from devastating personal losses.

Shrestha filmed the river at Trishuli Bazar and later posted the footage on Facebook. He said the video reminds him of running from the flood, watching people and houses being swept away, and remembering his mother. The article states that he lost his home and farmland. Thapa filmed the approaching wave near a bridge after returning from a trip for festival ingredients.

Thapa watched his fields disappear, followed by houses. He later said the footage brings back memories of friends and brothers and the transformed landscape. He also lost his mother. Both men now find the videos almost too painful to watch, despite their worldwide reach.

The disaster’s human and physical scale was enormous. By early October, police had recovered more than 1,450 bodies across eight districts. A government assessment counted 5,285 people as still missing. These figures show why individual faces appearing in flood videos became important evidence that some people had survived.

The bridge damage was similarly severe. Of 41 bridges between the Miteri Bridge in Rasuwa and Malekhu in Dhading, 35 were damaged. The Department of Roads said 32 were completely destroyed. The bridge where Shrestha and Thapa stood was among the structures lost.

The figures describe more than isolated damage. They show a disaster that disrupted crossings and devastated entire towns along the Bhotekoshi corridor. The article does not provide a final death or damage total. It does show that recovery continued while thousands remained unaccounted for and key transport links had disappeared.

A glacial collapse is a sudden breakdown or fall of glacier-related ice and material. It can release ice, rock, and debris at once. This differs from ordinary river swelling because the river receives a huge volume of material suddenly, rather than rising gradually from steady rainfall or runoff.

The article links the August 26 flood to a massive glacial collapse in the Lhende valley near the Nepal-China border. The collapse sent rock, ice, and debris down into the Bhotekoshi river. That influx produced the unprecedented disaster described in the report. The article does not give further technical details about the collapse itself.

Once the material entered the river, the flow became a powerful wave. It rushed through the Bhotekoshi corridor, sweeping away fields, houses, bridges, and other structures. The event’s consequences were still unfolding by early October, when more than 1,450 bodies had been recovered and 5,285 people remained missing.

The flood was unusually sudden because it was not simply a normal rise in river level. Thapa said rivers in the area usually swell slowly and touch the banks. This event arrived all at once, with a roar. That difference left people little time to react, even after warnings were broadcast.

The key mechanism was the massive glacial collapse in Lhende valley. It sent rock, ice, and debris into the Bhotekoshi river near the Nepal-China border. The sudden release displaced and accelerated water, producing the wave that Thapa recorded. The torrent carried enough force to remove fields, houses, and bridges.

Thapa initially crossed the bridge after hearing a warning, treating the trip as ordinary. When he heard the wave, he stopped filming, then ran after a fallen pole blocked his motorcycle. His experience shows the danger of the flood’s speed: warning existed, but the river changed faster than people expected.

The flood carried rock, ice, and debris downstream with enough force to transform the Bhotekoshi corridor. It swept through riverbank settlements, destroyed homes and farmland, and turned familiar places into scenes of devastation. The article describes landscapes becoming a barren desert after the water passed.

Thapa recorded the destruction as it happened. He watched the water take his fields and then houses, one after another. A fallen pole blocked his motorcycle, while a nearby man shouted for him to run. The bridge where Thapa and Shrestha stood later disappeared, and 35 of 41 bridges along the route were damaged.

The human consequences were severe. By early October, police had recovered more than 1,450 bodies, while 5,285 people remained missing. Shrestha lost his home and farmland, and Thapa lost his mother. The damage therefore reached beyond buildings, affecting families, livelihoods, transport, and entire towns.

Surviving a disaster does not erase what a person saw or felt during it. A recording can preserve the sounds, sights, and decisions of those minutes, making the event feel present again. In this case, the videos show people fleeing, houses disappearing, and landscapes being transformed.

Shrestha said watching his video would give him trauma because it reminds him of running, people being swept away, and his mother. He has not watched it since it went viral. Thapa watched his recording two or three times in the weeks afterward, then stopped. He said his heart could not take seeing familiar places become a barren desert.

Their reactions show why viral footage can have a painful double effect. It gives millions a view of the disaster and confirms that the filmmakers survived. But for the survivors, every replay can reopen grief, fear, and memories of people and places they lost.
