There is a nice article on slow moving landslides at Nature.com. They discuss the use of InSAR technology and point out how a number of landslides in the news over the past several years have had at least some movement before a catastrophic event. To me, the interesting part is just how a topic of interest to geoprofessionals is covered by scientists who perhaps aren’t experts in these areas. They also mention some of the more infamous slow moving landslides that are currently being researched. It’s worth a quick scan.
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.
A massive landslide in the little town of Nachterstedt in Eastern Germany early on Saturday morning local time caused two houses to vanish into a nearby lake. Three people are believed to have been in the buildings at the time of the slide. Rescue efforts are still on going and had to be halted during the night but were resumed the next morning. Helicopters with infrared cameras and dogs were used to find the missing people, but with no success so far. Approximately 60 residents of nearby buildings had to be evacuated and put up in emergency shelters. (Photo by Spiegel Online) [Editor] More after the break. [/Editor]
