Abstract :
Arctic and mountainous periglacial areas are subject to intense freezing cycles and characterized by remarkable surface displacement. We used TerraSAR-X interferometry to analyze the seasonal surface displacement on two regions in Alaska and Switzerland. In both cases, TerraSAR-X interferograms with an 11 days time interval are computed in series in order to maximize coherence. Seasonal subsidence maps highlight surface displacements of several centimeters while time-series show non-linear behaviors of the movements.
