A massive flood struck Nepal on August 26, killing over 1,400 people and leaving 6,000 missing. China's embassy rejected claims it withheld satellite data that could have provided earlier warning. Nepal's disaster authority said China approached Nepal several times, but Nepal failed to finalize a data-sharing agreement.

Key Facts

Over 1,400 bodies have been recovered on the Nepali side, with 6,000 still missing.
A glacier on Langtang Lirung's south slope fractured at 10:52 a.m. China time on August 26, triggering the flood.
The debris flow covered 22 kilometers and reached Gyirong Port on the Chinese side in about seven minutes.
NDRRMA director Dr Prakash Pokhrel said China approached Nepal several times, but Nepal failed to finalize a data-sharing agreement.
A barrier lake remains at the collapse site, and a second flood is still possible, according to both governments.

Blame and Response

Nepali social media split into two camps after the flood, with one blaming China for withholding satellite and disaster monitoring data. China's embassy in Kathmandu called the claims 'completely false and misleading,' insisting Beijing shared information in time. NDRRMA director Dr Prakash Pokhrel said the Nepali side needs to be more proactive to finalize the data-sharing agreement. Survivors and local officials said there simply wasn't enough time to react before the disaster arrived.

Scientific Reconstruction

Researchers from the Chinese Academy of Sciences' Institute of Mountain Hazards and Environment published a technical reconstruction of the disaster. They found that a glacier at roughly 5,200 meters elevation fractured at 10:52 a.m. China time, sending an ice-rock avalanche that grew into a debris flow. The debris covered 22 kilometers and reached Gyirong Port in about seven minutes, an average speed of nearly 50 meters a second. Researcher Su Pengcheng attributed the collapse to long-term glacier instability driven by climate warming, not to any specific weather pattern.

Ongoing Risk

Three weeks after the disaster, Nepal's disaster authorities are still revising the death toll upward. Over 1,400 bodies have been recovered and 6,000 are still missing on the Nepali side alone. Dozens more are dead or missing in Tibet. A barrier lake at the collapse site remains, and a second flood is still possible, according to both governments.
