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)

These are some really fantastic photos of the Devil’s Slide tunnel construction. For those who aren’t familiar, the tunnels will be bypassing a particularly landslide and rockslide-prone portion of the California Coast that is currently […]
Utah Releases Landslide Susceptibility Map
The Utah Geologic Survey has released a "Landslide Susceptibility Map of Utah". They apparently relied quite heavily on GIS based thresholding of existing slope angles but only after they had statistically analyzed failure angles for particular geologic units. So it sounds like they throw the known landslides, the geologic map of Utah and a DEM into the GIS a blend it all up. Perhaps a slight oversimplification!
Landslide Closes SR 14 in Utah
A large landslide has closed SR 14 east of Cedar City, Utah. UDOT expects that the road will be closed for up to 2 weeks for cleanup and to ensure that the slope is safe. Boulders up to an estimated 20 tons are now blocking the road and will likely need to be blasted down to a smaller size. A UDOT spokesman interviewed on the video shown after the break estimate the size of the slide at 700 to 800-ft long and 10 to 12-ft thick.
