The European VLBI Network activity in geodesy: crustal deformation in Europe
Authors:P Tomasi  M J Rioja  P Sarti
Abstract:The European VLBI Network has been performing a regular series of geodetic observations (EUROPE) whose main aim is to detect and monitor deformations in the European part of the Eurasian plate with high accuracy. The interaction between the African and Eurasian plates drives the tectonic motions detected in the Southern part of Europe that, with the spreading of the Middle Atlantic ridge and other local geophysical (e.g., post-glacial rebound) and geological phenomena, determine the overall crustal deformation of the region. We present the latest results obtained from the analysis of the EUROPE campaigns of observations; for certain stations, we have integrated other data acquired during different campaigns that involved at least three antennae of the network. In particular, for Ny Aalesund, we had to increase further the amount of data by using 144 experiments providing a more continuous and redundant data span to ensure a stronger statistical solution and a network with better spatial distribution. We present the velocities estimated for the antennas in the European geodetic network, along with an interpretation within their local geophysical frame.
