Rescue workers searched for hundreds of missing people Thursday after a wall of mud and rock collapsed into a river on the Himalayan border between Nepal and Tibet. The event occurred Wednesday, triggering flash floods that swept through mountain valleys and towns. As of Wednesday evening, Nepal police reported that 157 bodies had been recovered.
The disaster occurred in a mountainous region frequented by pilgrims and trekkers. Early reports from Nepali officials indicated an earthquake may have caused a glacial collapse, though the U.S. Geological Survey later stated the seismic activity recorded was likely the energy generated by the falling rock and ice itself. Satellite imagery from Planet Labs suggested a landslide triggered a debris-laden flood in the Lhende River, approximately 20 kilometers northeast of the Rasuwagadhi border crossing.
Officials at Nepal’s tourism ministry reported that over 400 tourists were missing, including approximately 340 foreign nationals. Many victims were traveling to Kailash Mansarovar, a high-altitude pilgrimage site in Tibet. Sunil Sharma, a Nepal tourism board spokesperson, stated that the missing include 47 Americans, 34 Australians, 33 Britons, and 24 Canadians. China’s state broadcaster reported three deaths and 265 people missing in Gyirong county, where mudslides destroyed roads and communication links.
For those in the affected mountain districts like Rasuwa, which has a population of 50,000, the daily impact is a total loss of essential services. Residents will notice the complete absence of electricity and communications as hydropower infrastructure and roads have been destroyed. Survivors described losing homes and family members in seconds as mud and water reached heights that engulfed entire buildings. Rescue efforts are currently constrained by geography; helicopters have been unable to land in certain areas like Syapru Besi and Timure because rivers are flowing above their normal courses.
The long-term effects involve significant damage to regional infrastructure and international travel safety. The destruction of the Gyirong border port, a major land crossing between China and Nepal, disrupts trade and transit routes. Furthermore, the event sets a precedent for how seismic and glacial monitoring is interpreted in the Himalayas. As of Thursday, search and rescue operations remain the priority, though no specific deadline for completing the recovery or restoring power and road access has been established. Status updates are expected as rescue teams attempt to reach isolated border ports.
