Kinematic and morphological inventories of slope movement in Northern Norway

DOI

We developed simplified ground velocity products based on Interferometric Synthetic Aperture Radar (InSAR) to inventory slope movements in a ca 7500 km2 region in Northern Norway. We used a multiple temporal baseline InSAR stacking procedure based on 2015–2019 ascending and descending snow-free Sentinel-1 images to take advantage of a large set of interferograms and exploit different detection capabilities. Moving areas were identified, classified according to six velocity brackets, and morphologically associated to six landform types (rock glaciers, rockslides, glaciers/moraines, talus/scree deposits, solifluction/cryoturbation and composite landforms). We updated the pre-existing inventories of rock glaciers and rockslides in the region using InSAR kinematics. Landform delineations and divisions were refined, and newly detected landforms (54 rock glaciers and 20 rockslides) incorporated into the databases. The updated inventories consist of 414 rock glacier units within 340 single- or multi-unit(s) systems and 117 rockslides. Based on InSAR, a kinematic attribute assigned to each inventoried landform documents the magnitude order of the movement.
