A second barrier lake has formed in Tibet after a landslide created a fresh debris blockage downstream of an existing lake, prompting authorities to relocate nearby residents as a precaution.
A new barrier lake has emerged in Tibet's Gyirong region following a landslide event detected on Saturday, according to Chinese state media reports. The phenomenon occurs when debris accumulates in a river channel, effectively damming the water flow. The newly formed lake is situated approximately 2.8 kilometres downstream of an earlier barrier lake on the Pruqpu Qiang Zangbu River.
The original barrier lake had developed in response to recent flash flooding and had been naturally reducing in volume, though concerns remained about potential additional flooding risks from its presence. The latest landslide was identified through monitoring drone surveillance, which captured the debris displacement and subsequent water impoundment.
Chinese authorities have taken swift action to manage the situation. The Ministry of Emergency Management assembled expert teams to evaluate the developing circumstances, while rescue personnel stationed near Gyirong Port have been relocated to safer locations as a precautionary measure. The movements reflect official concern about potential hazards posed by the newly formed barrier lake, though specific details about immediate risks remain limited in available reports.
