Landslide Causes Train to Derail into Mississippi River

A huge 35,000 to 40,000 cubic yard landslide has blocked Highway 26/89 for about 300 feet with material about 40 feet high. The slide is about 2000 feet long, terminating in the Snake River. It […]

On March 21, 2008 a landslide caused the closure of Arizona State Route 87 between Payson and Phoenix near mile post 224. So far there are no official estimates as to the size, but based on aerial photos, it appears to be at least 50,000 sq-ft in plan. The offset at the head scarps was approximately 2-meters (6.6-ft) according to AZGS Geologists on site. It appears to have been a rotational slide as the toe of the landslide heaved the southbound roadway up by as much as 1-meter (3.3 ft). There was an existing soil-nail retaining wall on the slope that was destroyed by the slide as well.  Lateral deformations can be seen in photos of the median barrier and the roadway striping. The deformations extended into the northbound lanes as well. More photos and links after the break. (Photo by ADOT)

NASA scientists are building an open global inventory of landslides with the goal of improving predictive models for landslides. The data is crowd-sourced and some are scraped from news sources as well.  Anyone can download […]
