Geology.com has put together an excellent overview of some of these issues related to home owners insurance and geologic hazards. It is a great resource for friends, relatives and associates looking to buy homes. Hopefully they will be able to recognize if there might be a potential risk, and seek out the services of a geologist or engineer before they put their investment at risk.
In Sichuan Province, China, they were still in the recovery process from the devastating 2008 earthquake when a series of landslides, rockfall, mudslides and flooding has hit the region. Dave’s Landslide Blog has excellent coverage as usual on the slide pictured here, which blocked a major road, hindering rescue efforts. (Photo Xinhua/Jiang Hongjing)
A remarkable video of the aftermath of a bridge destroyed by one of these rockfall / landslide events is shown below. The destruction is pretty profound. (Via Geology.com)
Also on Dave’s blog, a landslide in Guangxi caused a train to derail, killing 4 people and injuring 50. My heart truly goes out to the people of those portions of China, particularly in Sichuan as they have been through so much.
The Colorado Geologic Survey has a very comprehensive overview of the geologic hazard of rockfall in all its many forms in their latest issue of RockTalk newsletter. The entire 24-page newsletter is devoted to various aspects of the problem, mitigation options and case studies all with excellent photos. I highly recommend that you check it out.
