In late August, a catastrophic flood struck the Rasuwa district in northern Nepal. A massive section of ice, rock, and soil collapsed near the border with China. This debris fell into a mountain stream and blocked the water for about 18 hours. On 26 August, the temporary barrier burst, sending water, mud, and boulders rushing down the valley.
The flood caused massive destruction across the region. More than 1,000 people died, thousands went missing, and rescue workers saved nearly 12,000 survivors. The rushing water destroyed bridges, roads, and hydropower facilities. As a result, authorities had to close an essential trade route between Nepal and Tibet.
Scientists explain that global warming is making these disasters more common in the Himalayas. Rising temperatures melt glaciers and make steep mountainsides unstable. In this region, avalanches, landslides, and floods often happen together in rapid chains.
Traditional flood systems only monitor rainfall, so they cannot predict sudden rockfalls or collapsing ice. Therefore, experts urge governments to install seismic sensors, river gauges, and better local warning networks to protect mountain communities.
