Event description

 

According to an investigation by the Chengdu Institute of Geography of the Chinese Academy of Sciences, there were three burst events recorded in mid August 1968, 1969, and 1970 (LIGG/WECS/NEA 1988). A huge fan-shaped mass of debris was deposited at the confluence of the lake drainage channel and the main river course. The estimated sediment deposit is about 4.59 million m3. The distance from the glacier to the lake is 0.5 km. The flood damaged the highway and concrete bridges of Desha No.1 in Tibet (PR China). The damage inside Nepal is unknown.
