The Chinese government has issued a stern warning that a newly formed barrier lake—created by a massive landslide that rattled the Nepal‑Tibet border—could breach its banks and unleash a second flood downstream.


The alert follows last Wednesday’s deadly flash flood in the same area, which scientists say was triggered when a mountain glacier collapsed into the river. The resulting surge carved a new channel through the valley, leaving residents stranded.


Chinese emergency officials, monitoring the lake’s water level, flagged a “high risk” of rupture. Rescue teams on the ground fear that a sudden overflow could overwhelm the already strained infrastructure and cause widespread damage.


The incident highlights the growing vulnerability of high‑altitude communities to sudden geological changes, especially amid climate‑driven glacier melt. Authorities are now calling for accelerated monitoring and emergency response plans to mitigate the looming threat.
