Himalayan Flood Disaster: Experts Warn of New Flooding Risk Between Tibet and Nepal

Experts are sounding the alarm for further flooding in the Himalayan region after a devastating flash flood struck the mountainous area straddling Tibet and Nepal. Chinese authorities have stated there is a "high risk" of renewed flooding, particularly concerning a newly formed lake. This lake, created by the flash flood, could swell to approximately three million cubic meters if rainfall persists over the next three days, according to China's Ministry of Water Resources.

If the lake overflows its banks, the water masses could cause further damage in the disaster area.

Should the lake breach its banks, the resulting water surge could inflict further devastation on the already disaster-stricken areas. This threat extends to the crucial China-Nepal border crossing at Gyirong and communities downstream. Chinese state media reported that over 1,000 individuals, comprising 555 tourists and 555 residents, have been safely evacuated from the affected zone. Earlier reports from local authorities had indicated approximately 1,400 people were missing, including pilgrims and foreign nationals.

In Nepal, the disaster has left a trail of destruction, with authorities reporting dozens of bridges and nearly 40 kilometers of roads destroyed. The Nepalese Red Cross stated that around 1,200 people have been displaced from at least three villages. In Tibet, the area around the Gyirong border crossing is covered in more than a meter and a half of mud, according to Chinese state broadcaster CCTV, with roads leading to the crossing also damaged.

Over 1,000 people have been brought to safety.

The United Nations has responded by releasing $2 million from an emergency relief fund to provide medical aid, shelter, and water. The initial flash flood, which occurred on Wednesday, carved a path of destruction over 160 kilometers long through Nepal, obliterating entire villages. The U.S. Geological Survey (USGS) suggests that a glacial lake outburst flood, likely triggered by a glacier collapse, was the probable cause of the catastrophic event.

Two million US dollars have been released from an emergency fund to provide medical care, accommodation, and water.
