A 12 million cubic meter landslide occurred in Wulong county in southwest China’s Chongqing Municipality on Friday. There are some excellent blog posts on this rockslide at Dave’s Landslide Blog. This massive failure occurred in the vicinity of a mine (Iron ore?) being run by a private company since 2004 after Chinese government geologists labeled the site dangerous resulting in it being closed in 2000 after over 50-years of production.

Geotechnical Engineering Challenges of British Columbia’s Sea-to-Sky Highway, gateway to the 2010 Vancouver Olympic Games
I don’t know about you, but I’ve been enjoying watching the 2010 Olympic Winter games over the past few days. If you have, you know that Whistler is the venue for many of the sports including alpine skiing, luge, skeleton, bobsled, ski jumping, biathlon and cross-country skiing among others. The Whistler area is located about 50-miles or so North of Vancouver. In order to get to Whistler, you need to drive along Highway 99, better known as the Sea-to-Sky Highway. This highway has a long history of geotechnical problems, including some significant structurally controlled rockslides and landslides. In the years leading up to these Olympic Games a fair amount of work was done on the highway with some significant geotechnical innovations.
The people living on the eastern bank of the Traunsee (map on following page) in Austria are able to observe geology in motion these days. About one million tons of soil and rock are moving in a slow landslide toward the lake, throwing over trees (picture at left) and threatening to take parts of a village with them. Moreâ€¦
