Glacier collapse triggers mudslide hitting border port in China's Xizang: expert

A massive mudslide that caused casualties and left a large number of people missing at the border port of Gyirong in southwest China's Xizang Autonomous Region was triggered by the collapse of glacier on the Nepalese side at a higher elevation, an expert said.

The collapse sent masses of debris rapidly downhill, which swept up moraine material along the way to form a mudslide that struck Gyirong Port before moving downstream toward Nepal, said Guo Zhaocheng, an expert with the Ministry of Natural Resources.
