Scientists reveal what caused deadly flash floods in Nepal

A preliminary report by Nepalese scientists found that last week's flash floods were caused by an ice-rock avalanche from Langtang–Lirung peak, not a glacial lake outburst flood (GLOF). Satellite images showed no evidence of a GLOF. The mass began falling around 8:37am on August 26 from 5,200 metres, reaching Lhende River before surging downstream through the Bhotekoshi and Trishuli rivers.
