Nepal, Tibet Issue Fresh Flood Warnings as Over 1,400 Remain Missing
KATHMANDU, NEPAL — WEB DESK: Authorities in Nepal and China issued fresh flood warnings on Friday as rescue teams searched for more than 1,400 people still missing after a catastrophic flood and landslide disaster devastated communities along the remote Nepal-Tibet border.
The new threat is complicating an already difficult search-and-rescue operation after a massive surge of freezing water, mud, rocks and debris swept through Himalayan valleys on August 26, destroying villages, bridges, roads and other infrastructure.
The latest reports put the death toll at at least 469 in Nepal, while Chinese authorities have reported additional deaths in Tibet. The toll has continued to change as rescuers recover more bodies from downstream areas.
New Lake Raises Fears of Another Flood
The immediate concern centres on a large lake formed behind debris generated by the disaster on the Tibetan side of the border.
The barrier lake has begun overflowing, creating fears that additional water and debris could rush downstream towards already devastated communities.
Chinese authorities temporarily halted rescue operations near the disaster epicentre because of the danger. Teams that had reached the affected area were instructed to withdraw approximately one kilometre and await further instructions.
Nepalese authorities have also placed communities along the Bhote Koshi, Trishuli and Narayani river systems on heightened alert.
Residents and rescue workers in vulnerable areas, including parts of Rasuwa and Nuwakot, have been advised to move to safer ground as officials monitor upstream conditions.
More Than 1,400 People Still Missing
The scale of the disaster remains uncertain because hundreds of people are still unaccounted for across Nepal and Tibet.
Many of those missing are foreign nationals, including tourists, trekkers and Hindu pilgrims who had travelled to the Himalayan region.
Indian nationals make up the largest group of missing foreigners, while the United States has said around 90 American citizens were out of contact, according to AFP reporting. Citizens of Australia, Britain, Malaysia, the Netherlands, Portugal, South Africa and South Korea were also reported missing.
Hundreds of travellers were in the region for pilgrimages to Mount Kailash, a sacred mountain in Tibet revered by Hindus, Buddhists, Jains and followers of the Bon tradition.
Chinese authorities said 555 stranded tourists and 499 local residents had been evacuated from affected areas in Tibet. Nearly 800 emergency personnel were deployed along with drones, satellites, speedboats and sniffer dogs.
What Caused the Nepal-Tibet Disaster?
Early reports initially raised the possibility that an earthquake had triggered the catastrophe.
However, the US Geological Survey (USGS) later determined that seismic signals initially interpreted as an earthquake were associated with a glacial collapse and massive debris flow.
The collapse unleashed an enormous volume of ice, rock, water and sediment into the river system, producing what witnesses and experts described as a tsunami-like surge through the narrow Himalayan valleys.
Reuters reported that preliminary geological assessments pointed towards an ice avalanche-induced mudslide, with the disaster illustrating the severe hazards posed by unstable high-altitude glaciers and mountain terrain.
Scientists caution, however, that it is still too early to attribute this specific event directly to climate change. The wider Himalayan region is warming rapidly, and researchers have long warned that changing glaciers and glacial lakes can increase disaster risks.
Entire Communities Hit by Floodwaters
The force of the flood sent water and debris far downstream into Nepal, destroying homes, roads, bridges and other infrastructure.
Nepal Police said bodies had been recovered from several districts, including Chitwan, Nawalparasi East, Gorkha, Nuwakot, Dhading, Tanahu, Nawalparasi West and Rasuwa.
At least 1,545 people had been rescued from affected areas, with dozens receiving hospital treatment in Kathmandu, according to Nepalese authorities.
Prime Minister Balendra Shah visited some of the worst-hit communities and instructed authorities to provide immediate assistance to displaced families and reopen blocked roads.
Rescue Effort Remains Dangerous
The latest warnings mean rescuers are confronting two simultaneous challenges: finding survivors and recovering victims from the original disaster while preparing for the possibility of another destructive surge.
Damaged roads, destroyed bridges, unstable slopes and disrupted communications are already restricting access to remote areas.
An overflowing or collapsing debris-dammed lake could send another wave downstream with little warning, forcing authorities to balance the urgency of searching for missing people against the safety of rescue personnel.
With more than 1,400 people still missing, the confirmed death toll could rise further as rescue teams reach isolated areas and continue searching downstream.
