The combined death toll from catastrophic flash floods and mudslides along the Nepal-China border has exceeded 1,000, official data showed on Tuesday, a week after a glacial collapse triggered massive debris flows across the region.
According to Nepal’s National Disaster Risk Reduction and Management Authority (NDRRMA), emergency responders confirmed 84 additional fatalities, bringing the total deaths on the Nepalese side to 987. An estimated 3,916 people remain missing in Nepal, including 583 foreign nationals. Disrupted operations at several regional energy sites account for a significant portion of those missing, with 639 personnel deployed at various hydropower facilities unaccounted for.
Across the border in China's Tibet Autonomous Region (Xizang), authorities confirmed 16 fatalities, with search efforts ongoing for 546 missing individuals, including 261 foreign nationals. Combined figures from both nations place the total death toll at 1,003, with 4,462 people reported missing, including 844 foreigners. Indian nationals represent the largest group of missing foreign citizens, with 275 individuals reported missing alongside 100 Chinese nationals.
The disaster originated on August 26 when a glacier situated on Mount Langtang Lirung fractured at an elevation of approximately 5,200 meters. The resulting ice and rock avalanche triggered a massive debris flow that surged through high-altitude river valleys.
The deluge caused widespread destruction across Nepal's Rasuwa, Nuwakot, Dhading, and Kavre districts, as well as the Kathmandu Valley. On the Chinese side, the debris flow buried the Gyirong border crossing. Chinese state media reported that emergency rescue teams required a ten-hour trek through rugged terrain to reach Gyirong, where existing infrastructure and border facilities were entirely obliterated.
With recovery efforts mounting, Nepalese authorities have requested international assistance, seeking mobile freezers, DNA testing supplies, remote-sensing technology, and aerial drones to assist in mapping destroyed sectors. Specialized search and rescue teams from China, South Korea, and India have been deployed to assist local emergency forces. Operations remain severely hampered by damaged road networks, destroyed bridges, and severed telecommunications across the mountainous terrain.
