What We Know — and Don't Know — About What Caused the Nepal Flood Wave
Scientists say a landslide likely triggered the flood, which may take weeks or months to fully explain, after ice and rock tore into a river valley.
- The U.S. Geological Survey clarified that a powerful landslide, not an earthquake, caused seismic activity near the Nepal-China border north of Kathmandu, correcting initial reports of a 4.4 magnitude earthquake.
- An "avalanche" of ice and rock tore down a mountainside into the Lhende Khola River, a tributary of the Bhote Koshi River, creating a devastating torrent of floodwater through the region.
- The landslide itself generated seismic energy equivalent to a magnitude 5.2 earthquake, according to the USGS, with experts believing a large glacier chunk sheared off and cascaded downward.
- Satellite imagery analysis suggests no major lakes are upstream, making "Glacial lake outbursts" unlikely, Wolfgang Schwanghart, a professor at the Freie Universität Berlin in Germany, told CNN.
- Climate change is destabilizing rocky mountainsides across the Hindu Kush Himalaya, posing risks to nearly 2 million people living downstream as glacial melting accelerates extreme weather events.

What caused the Nepal flood wave? Here’s what we know
(CNN) — The cause of the powerful torrents of floodwater that carved a devastating path through Nepal and Tibet — swallowing towns, roads and bridges — is not yet clear, but Nepal is a hotspot for climate disasters as the…
Nepal was hit by a storm near the Tibetan border in China, which caused at least over a hundred deaths and several missing. But, after all, was it the landsliding that caused an earthquake? Or was it the opposite?
This morning a huge avalanche of ice and rocks caused a catastrophe in Nepal that already claimed more than a hundred lives. Some experts already describe it as a flood. What is it, how does it originate and why it caused so many disasters in Nepal? This is what we know. What is a flood? According to the Royal Spanish Academy a flood is the sudden increase in the flow of a river, which often causes a catastrophic flood. Rianda in Nepal / Photo: …
