EPISODIC LANDSLIDE MOVEMENT IN ICELAND STUDIED USING SAR INTERFEROMETRY
While there is abundant geomorphologic evidence for landslides in Iceland, it is in most cases unknown whether or not these landslides are actively creeping. Here we use Interferometric Synthetic Aperture Radar (InSAR) to assess its monitoring capabilities on three landslides that are known to be cr...
