How a mountain collapse triggered Nepal’s deadly flood in just 7 minutes | The Climate Economy

On April 18, 2017, a mountain collapse in Nepal triggered one of the country's deadliest flood disasters, unfolding in just seven minutes. Initially, scientists were puzzled by the strange warning signs that preceded the catastrophic event. The river that usually flowed calmly through the region suddenly began to shrink, raising concerns among locals and authorities alike.

However, what initially appeared to be an earthquake turned out to be seismic signals from the impending collapse. The mountain, weakened by years of erosion and heavy rainfall, suddenly gave way, releasing an immense amount of rock, ice, and water into the surrounding valley. In just seven minutes, the torrential wave of debris and water swept through the area, destroying everything in its path and claiming countless lives.

Experts now say that this disaster highlights the need for improved monitoring of Himalayan hazards. As climate change continues to reshape mountain regions, the potential for sudden and devastating floods like the one in Nepal increases. By understanding the warning signs and implementing more effective monitoring systems, experts hope to prevent future tragedies and protect vulnerable communities in the region.
