The video lasts only seconds. A dark wall appears from behind the buildings at Gyirong, on the Chinese side of the Nepal-Tibet border, resembling almost a black cloud. It gathers shape and speed: water, mud, boulders, ice, and rock surging down the valley. The timestamp reads 10:59:53 local time.

What unfolded in the following minutes remains challenging to reconstruct. However, fragments of video and satellite imagery offer glimpses of the destruction:

  • Gyirong Devastation: Much of the border complex appears wiped out, with buildings once lining the valley floor gone.
  • Rasuwagadhi Loss: Across the frontier, Rasuwagadhi in Nepal's Rasuwa district suffered extensive damage. The Friendship Bridge connecting Nepal and China, along with Nepal's immigration and customs facilities, was swept away.

"This is a historic travel route...geologically vulnerable," explains Ajay Dixit, a Kathmandu-based hydrologist.

The Impact:

  • Over 100 Indians were in or around the crossing at the time.
  • At least 275 Indians remain missing in Nepal, according to India's foreign ministry.
  • Nepal's immigration system recorded its final transaction just before 9 am local time, with four employees going missing.

Foreign Nationals:

The last recorded transactions included:

  • 32 Indians
  • 12 Chinese nationals
  • 9 Americans
  • Citizens of Britain, Canada, Australia, and Italy.
