Full coverage: 6.5-Magnitude Quake Hits Southwest China's Yunnan
One of the great dangers of earthquakes in mountainous areas are landslides that block the flow of rivers, and that’s what happened on a stretch of the Niulan River in Yunnan. A large lake has formed behind a dam created by the collapse of mountain slope since Sunday’s quake. Some 30,000 villagers downstream are being threatened by the rising lake, and Chinese authorities have brought in more than 100 heavy machines and some 400 personnel to remove the blockage.

While demolition experts use dynamite to blow the landslide-caused dam,  excavators are digging a channel through the huge mound of debris....

"This blast is on the upstream side of the blockage, it will allow our machines to get through. It will create a channel 50 to 60 meters long," said Yu Tao, chief detonation engineer.

More rain is expected, making the work both tougher and more urgent....The lake on the Niulan River will overflow the dam if it rises another 36 meters.

"The digging work will be accelerated, paving the way towards our target of finishing the channel by August 12th," said Zhai Congfu, political commissar of Hydropower Engineering Troops.
Dangers are growing upstream. The lake has already forced 9,000 villagers to relocate. 90 hectares of farmland, 92 homes and 7 kilometers of roads are now underwater. Engineers expect to pull the plug on the swelling lake when they finish carving their channel through dam by Tuesday.
