Exciting news! ARGO-E GROUP contributed to recent research on landslides published in the journal Landslides, and co-authored the paper, "Enabling 3D landslide event statistics using satellite and UAV‑enabled topographic differencing."

This research by Clark, Zekkos, and Manousakis introduces a novel dataset of 3D landslide volumes derived using topographic differencing techniques. The study utilizes remotely sensed optical imagery and UAV data collected after the 2015 Lefkada earthquake in Greece to map approximately 700 landslides. By comparing pre- and post-earthquake digital elevation models (DEMs), the researchers quantify elevation changes and calculate landslide volumes. They assess the influence of methodology and data quality on these calculations.

The study thoroughly explores the relationship between landslide characteristics, geological factors, and ground motion, also analyzing common statistical measures, particularly frequency-area relationships, within the landslide inventory. The scientists' work ultimately promotes the use of these new remote sensing capabilities in hazard and geomorphic research in the future.

ARGO-E GROUP is proud to have been involved in this work, using advanced 3D analysis to better understand landslide hazards. The research data is even available online for others to use.
