California motorists can now avoid a dangerous and landslide-prone stretch of the Pacific Coast Highway, Devil’s Slide, through the tunnel bypass. This project has been a fascination of mine since the early days of GeoPrac. […]

Grant Wilcox, Geology Branch Chief with CALTRANS Office of Geotechnical Design West gave a presentation on the Devil’s Slide repair along PCH Highway 1 at the Southwest Geotechnical Engineer’s Conference on May 12 in Phoenix. I’ve posted about the projectherebefore. When I saw Mr. Wilcox, I knew he looked familiar but I couldn’t figure out why.

What follows are a few quick tidbits from his talk based on my notes. (Photo via Caltrans site).
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 […]
