Marin Clark Drone Mapping Video on YouTube

More than 20,000 landslides took place in Nepal during the Mw 7.8 Gorkha earthquake on April 25, 2015 . This video describes the landslide mapping efforts of Dr. Marin Clark and Dr. Dimitrios Zekkos from the University of Michigan, Dr. Josh West (University of Southern California), and Dr. Deepak Chamlagain (Tribhuhan University, Nepal).

The research team used drones and photogrammetry principles to view, map, and create 3D models of large rock slides, debris flows, and even rockfalls. The drone was particularly needed in this case, because of the steep topography and the large size and runout length of some of the landslides, that made it nearly impossible to map otherwise.

The video is narrated by Marin Clark. It was prepared by Geoengineer.org staff.
