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.

A 20 to 30-ft high retaining wall in a subdivision in San Antonio Texas failed on Sunday causing an evacuation of 80 homes. After an initial inspection, some 55 home-owners were allowed to return. The massive tension cracks that opened along the wall and behind it were 12-15-ft deep and 6-8-ft wide. Reportedly, the wall had problems even before the subdivision was even constructed. More after the break. (Photo by Jerry Lara – San Antonio Express-News)
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.
