KATHMANDU — Startling new satellite imagery has exposed the sheer magnitude of a massive glacier and mountainside collapse along the Nepal-China border, which triggered catastrophic transboundary flash floods.

Scientists confirmed that the sudden geological failure unleashed millions of tons of ice, boulders, and debris through narrow gorges, violently inundating riverside settlements along the Trishuli River.

Emergency response teams remain deployed as geologists warn that rapid climate-induced thawing in high-altitude Himalayan ranges poses an escalating peril to vulnerable downstream regions.
