A recent landslide on the Nepal‑Tibet border has left a large lake trapped behind a natural dam. Chinese authorities have issued a high‑risk warning that the lake could suddenly break its banks, sending a flood downstream into populated valleys. This warning follows a deadly flash flood that struck the region earlier this week, when a glacier collapse poured water into the river. Rescue teams in both countries are now monitoring the lake’s stability and preparing for possible evacuation scenarios. The situation highlights how climate‑driven events are putting mountain communities at heightened risk.
