Abstract

We computed 43 differential SAR interferograms of ERS data. DEM is derived from GTOPO30 (low frequency) and stacking of ASTER DEMs. Tropospheric patterns are estimated and compensated from standard atmospheric models and meteorological data (cloud dependant fringes). Low frequency Ionospheric fringes are compensated from TEC maps derived from gps. Residual non tectonic fringes are filtered using an Principal Component Analysis procedure based on elastic modeling of the deformation. Results show strain accumulation of about 3 mm/year. We finally investigated the potential of MERIS/ASAR data over this area from real data.
