KATHMANDU, NEPAL | Rescue teams are searching for 1,468 people reported missing after catastrophic flash floods and landslides swept across communities along the Nepal-Tibet border, killing at least 392 people and destroying homes, roads, bridges and major infrastructure.

Nepal has reported 389 deaths, while authorities in Tibet, an autonomous region of China, have reported three deaths. The latest figures remain subject to change as rescuers reach isolated areas and authorities reconcile missing-person reports.

The disaster struck on Wednesday, August 26, after a massive ice-rock and glacier collapse in the Himalayan headwaters unleashed a sudden torrent of water, mud, rock and debris down the Lhende Khola and into the Bhote Koshi and Trishuli river systems. Reuters reported that the resulting flow devastated communities and infrastructure along a major Himalayan route linking Kathmandu and Lhasa.

Initial reports raised the possibility that an earthquake had triggered the disaster. Subsequent analysis, however, indicates that the seismic signal detected during the event was generated by the collapse itself. Scientists have focused on a massive ice-rock avalanche or glacier collapse that rapidly displaced water and generated a powerful debris flow. The precise sequence of events remains under investigation.

The scale of the disaster has made it difficult to determine the whereabouts of thousands of people. In Nepal, 910 people remain missing, including hundreds of foreign nationals. On the Chinese side, authorities have reported 558 people missing in Gyirong County, including 260 foreigners. Because the two countries maintain separate records and some reports may overlap, the combined figure should be treated as provisional.

Among those missing are tourists, pilgrims and workers from numerous countries. Many foreign nationals were traveling through the region toward Mount Kailash, one of Asia’s most important religious destinations. Indian nationals are among the largest groups affected, with 288 Indians reported missing in the latest figures.

The flooding devastated parts of Rasuwa district in Nepal and severely damaged Gyirong County and the Gyirong Port area on the Chinese side. Roads and bridges were swept away, buildings were buried in mud and communications and electricity supplies were disrupted, severely complicating rescue operations. Helicopters have been deployed to search for survivors and deliver emergency supplies to communities cut off by the destruction.

The danger has not ended. Debris has blocked waterways and created concerns about additional flooding if temporary water accumulations or newly formed glacial lakes breach. Authorities on both sides of the border have warned communities downstream to remain alert while rescue and monitoring operations continue.

The disaster has renewed concern over the growing risks facing communities in the Hindu Kush Himalaya, where glaciers are rapidly changing. The region’s glaciers provide water to major river systems that support hundreds of millions of people across Asia, while unstable slopes, melting ice and extreme weather can combine to produce sudden and destructive floods and debris flows.

Nepal has experienced several major glacier- and flood-related disasters in recent years. In August 2024, a glacial lake outburst flood devastated the Everest-region village of Thame. Earlier disasters have also demonstrated how landslides, river blockages and debris flows can combine in Nepal’s steep mountain terrain to turn localized events into major catastrophes.

For now, rescuers remain focused on finding survivors and accounting for the missing. With 392 confirmed deaths and 1,468 people still unaccounted for, authorities face the difficult task of determining the full human toll of a disaster that has transformed valleys and river corridors along one of the world’s most fragile and rapidly changing mountain regions.
