Clear-sky Pléiades acquisition of the Rasuwa landslide source area

After many attempts, CNES’s Pléiades satellites finally captured a clear-sky view of the source area of the devastating flood in Nepal. The stereoscopic acquisition enables the generation of a high-resolution DEM and consequently a geometrically accurate orthorectified image. Although I’m not involved in the scientific analysis, I could not resist taking a closer look at […]

New clear-sky image of the Rasuwa rock-ice avalanche

On 08 Sep 2026, Sentinel-2 acquired a clear-sky image near the release area of the landslide which caused the catastrophic flood in Nepal.
