A devastating flash flood triggered by a glacial lake outburst flood (GLOF) in Nepal’s remote trekking region has claimed at least 165 lives. The disaster occurred in a popular hiking area, catching many off guard. A significant number of the victims, estimated around 800, were foreign nationals undertaking a pilgrimage. Rescue teams are currently searching for nearly 1500 people who remain missing following the sudden surge of water. Authorities believe the GLOF was caused by a portion of a glacier breaking off, sending a torrent of water and debris down river valleys. The scale of the destruction is hampering rescue efforts, with damaged infrastructure and challenging terrain posing significant obstacles. This event highlights the increasing risks posed by glacial melt in the Himalayas due to climate change.
