ní pō ěr尼泊尔zhōng bù中部hóng shuǐ洪水hòu后de的jǐng shì警示
A massive avalanche occurred on a high mountain in central Nepal. Ice, snow, soil, and rocks rushed into a river, temporarily blocking the water.
The lake that formed quickly burst, and muddy water and huge boulders surged downstream like a wall.
The flood killed many people and washed away bridges, roads, power stations, and electricity transmission equipment, cutting off transportation in some northern areas.
Scientists still cannot determine whether an earthquake triggered the avalanche or whether the avalanche caused the ground shaking.
However, global warming is making ice and snow on high mountains less stable. As frozen ground thaws, the rocks and soil that were once held in place can also become loose more easily.
Heavy rain during the rainy season also saturates mountain slopes with water, further increasing the danger.
In recent years, similar disasters have occurred many times in the Himalayan region.
Nepal needs to strengthen mountain monitoring and cross-border early-warning systems so that residents can evacuate earlier. At the same time, it needs to build safer roads, bridges, and power facilities to prepare for possible increases in mountain floods in the future.
