The mountainous district is located about 120 km north of Kathmandu. As there was no rainfall in the area, residents did not have a warning about the deluge.The International Centre for Integrated Mountain Development, which works on climate and glacial conditions in Nepal, stated that experts were investigating if the flood was triggered by an ice-rock avalanche.Here’s more on this and other top updates:It was initially suspected that an earthquake could have caused the flash flood and mudslide. However, the United States Geological Survey said there was no earthquake in the area, the BBC reported.Water levels in the Trishuli river at Galchchi had reportedly risen by nine metres within 30 minutes, while levels at Malekhu rose by seven metres. “Preliminary assessment based on video footage and information from affected areas suggests that a large volume of ice and rock debris may have entered the Lende Khola, a tributary of the Bhotekoshi river,” stated the International Centre for Integrated Mountain Development. This could have generated a sudden surge that carried water, sediment and large boulders downstream, it added.Experts were also assessing whether debris had temporarily blocked the river, added the institute. If the impounded water was suddenly released, it could have caused a flash flood.Nine hydropower projects, 19 motorable bridges and 40 kilometres of highway have been swept away in the flood, reported The Kathmandu Post.
