What's happened
A glacier-triggered flash flood has collapsed into rivers near Nepal and Tibet, creating a barrier lake that has swelled to about 2.5 million cubic metres. Officials warn of a high risk of breach as authorities monitor rising water levels and potential secondary floods. Rescues continue, with hundreds dead and many missing as relief operations press on.

How we got here
The disaster followed a glacier collapse upstream, sending a torrent of ice, water, and debris into Himalayan river valleys. A natural dam formed behind this debris, creating a barrier lake that threatens downstream communities.
