Chinese authorities have issued a stark warning regarding a high risk that a newly formed lake, created in the wake of a recent landslide near the border of Nepal and Tibet, could breach its banks and unleash a secondary wave of destructive flooding downstream.
This heightened alert follows the deadly flash flood that struck the exact same region on Wednesday. Scientific experts have confirmed that the initial disaster was triggered when a mountain glacier abruptly collapsed directly into a river channel.

BBC China correspondent Laura Bicker has provided detailed explanations and ongoing coverage of the unfolding crisis, outlining the immense challenges facing rescue teams and vulnerable communities across the Himalayan region.
Natural barrier lakes formed by landslides or glacial collapses pose severe secondary threats because debris dams are typically unstable and prone to sudden structural failure under high water pressure. Monitoring these unstable water bodies is critical for preventing downstream catastrophes during ongoing adverse weather.
