Whilst landslides come in all sorts of shapes and sizes, the fundamental physics that controls material deformation on slopes is the same everywhere. I was reminded of this truism this week when Andrew Giles pointed out a large rockslide that occurred a few days ago, blocking Interstate 40 at Pigeon Gorge in North Carolina, USA. The Citizen-times.com website has a nice report and images of the slide:
