Nepal landslide sparks sudden flash flood after blocking river flow
A massive landslide in northern Nepal temporarily blocked a river before releasing a sudden rush of water. The impact registered as a seismic event on international monitors, though experts confirmed it was not an earthquake.
On the morning of August 26, a massive section of ice and rock collapsed onto the Lohende Khola River in northern Nepal, near the Nepal-China border in Rasuwa. The catastrophic landslide caused an immediate disruption to the natural course of the waterway, creating a temporary barrier that blocked the river's flow entirely for several critical minutes.
As the blockage gave way, the accumulated water surged forward, creating a powerful and sudden flash flood downstream. According to reports from Channel 24, the sheer force and sudden release of this enormous volume of water generated significant environmental impact and dynamic shifts within the local river system near the border region.
The tremendous physical impact of the landslide and the subsequent rush of water did not go unnoticed by global monitoring networks. The violent geological shift was captured by seismometers operating in various countries around the world, which registered the event as a sudden ground movement measuring 5.2 in magnitude.
Initial concerns that a major tectonic event had occurred were quickly dispelled by international scientific authorities. The United States Geological Survey officially clarified that the recorded 5.2-magnitude signal was not an earthquake at all, but rather the direct physical shock and ground-shaking impact of the massive mountain collapse in northern Nepal.
