Experts say a massive ice-rock fall from about 5,200 metres into the Lhende River triggered the devastating floods in Nepal, not an earthquake or glacial lake outburst. The disaster killed over 900 people and left more than 4,000 missing.

The devastating floods that swept through Nepal were triggered by a massive fall of ice and rock in the high Himalayas, not by an earthquake or glacial lake outburst flood (GLOF), according to experts. The flash floods near the Nepal-Tibet border on August 26 swept through the Bhotekoshi River corridor, destroying homes, roads and bridges and damaging hydropower projects. The death toll crossed 900, with over 4,000 people still missing, according to the National Disaster Risk Reduction and Management Authority. A study commissioned by the Nepal Environment Society (NES) found that a huge mass of ice, rock and debris fell from around 5,200 metres in the Langtang Lirung area of Rasuwa and entered the Lhende River, generating a debris-laden flood that raced downstream at up to 167 kmph.
