Fennoscandian strain rates from BIFROST GPS: A gravitating, thick-plate approach

Description
Summary:International audience The aim of this investigation is to develop a method for the analysis of crustal strain determined by station networks that continuously collect measurements of Global Navigation Satellite Systems (GNSS). The major new ingredient is that we require a simultaneous minimum of the observation error and the elastic and potential energy of a thick elastic and gravitating slab. From this outset the method pursues a general approach not limited to the origin of the deforming process nor to assumptions of lateral homogeniety of the elastic and density structure. One present limitation, however, is the assumption of vertical uniformity in elasticity, which is relevant in the flexure mode.
