Abstract :
This paper presents an investigation to the estimation of the surface movements over the region of Yakutsk using TerraSAR-X data acquired during two months. The interferometric phase generated from the data stack presents a deterministic behavior over the most of the image, due to short temporal baseline and frozen surface context, and reveals fringes due to surface deformation over different geo-morphologic objects as alluvial deposits, alasses and other thermokarstic depressions, but also on the Lena river.
