Chinese and Nepalese authorities restarted search and rescue efforts on Friday after a lake that had formed from debris at the epicentre of the flooding in Tibet threatened to overflow, state broadcaster CCTV reported. The lake had begun overflowing towards an area where rescue teams were headed, prompting a pause. By Friday, the threat had eased and operations resumed.
The death toll from the flash floods, which struck on Wednesday when a wall of mud and debris hit the Tibetan hub of Gyirong, now stands at 579, with more than 1,300 people missing. In Nepal, the official death toll has reached 469.
Satellite imagery suggests a glacier collapse high in the Himalayas was the primary cause, raising concerns that the climate crisis is destabilising the geology of mountain regions.
Among those unaccounted for are 38 Australians, according to a live update from Nine newspapers. The floods obliterated villages along the Nepal-Tibet border, with the majority of the missing believed to be tourists.
