A couple of weeks ago the Landslides Under a Microscope blog had two nice posts about Landslide Mitigation examples in Japan. The author references the book “Landslides in Japan” (1996), but I’m not sure if the photos were scanned from there, or came from the author’s own photo collection or what. But there was one post focusing on control works for landslide mitigation and another on restraint works for landslide mitigation. (Photo from Landslides Under a Microscope blog)
The Chilliwack Times reports that the City of Chilliwack will pay 80% of the assessed home value for up to 42 homes in an Eastern Hillside subdivision that are located on a slow moving landslide. The issue was first noticed in 2001 and several homes have had significant damage, but most are currently undamaged. The City denies any responsibility, but it’s legal counsel recommended a settlement. (Photo by Paul J. Henderson, Chilliwack Times)
Normally the geotechnical engineer for the subdivision would be held accountable. But apparently the slip surface is located 30-m below grade, much deeper than borings for a typical investigation for a subdivision. I wonder if there were any geologists consulted? Click through for a Google map view of the area and you can do your own armchair photogeology quarterbacking! Your heart does go out to the people losing their homes, they had no idea. But it could be worse, they could be in La Jolla and be getting squat.
Mud and debris from a small landslide closed a portion of Sepulveda Blvrd. In Westwood California on Thursday. The slide took out at least one local resident’s backyard and was large enough to block several lanes of the roadway with debris up to 6-ft high in addition to knocking out several power poles and disrupting service. The material was cleared up by 10pm but not before it cause some inconvenience to UCLA basketball fans on their way to watch their team beat Stanford. The LA Times reports that there were questions about possible broken water lines, of course it is the old "chicken or the egg" argument that’s been seen before (including on a recent landslide) about whether the broken water lines contributed to the landslide, or the landslide caused the water line breaks.
