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 landslide in Logan Utah caused a portion of a canal to fail, causing a second mudslide. Three people, a mother and two children, were believed to be buried when the mud and debris hit their home. Rescue efforts were halted fairly quickly because of concern regarding the stability of the hillside. So far I have not read any reports that the bodies have been recovered. Map, Videos and more after the break. (Photo by Mike Terry, Deseret News, hat tip to Landslides Under a Microscope Blog)
As 33 trapped miners waited more than 2,000-ft underground for their rescue, a whole team of Chilean government officials, mining engineers, equipment manufacturers and of course drillers came together get the job done. Jeff Hart, a driller from Denver, Colorado was one of the stars of the day. Hart was in Afghanistan drilling deep water wells when he got the call and hopped on a plane. He works for Kansas-based Layne Christensen, and along with 3 other Layne employees, he manned the Schramm T130 drill rig that was part of “Plan B” that eventually became the shaft from which the trapped miners were rescued.
On the drilling platform overseeing the drilling was James Stefanic of Layne, and crew members Matt Staffel, Doug Reeves and Jorge Herrera. The rig and I presume some of the support equipment was owned by Layne’s Latin America affiliate, Geotec Boyles Bros, SA. The drill bits were from Center Rock, Inc. of Berlin, Pennsylvania. The Center Rock CEO, Brandon Fisher, was on site throughout the operation as well.
