Crustal motions from space geodesy: a review from EPN, CEGRN, and HGRN data

摘要

From the Adria microplate, the main engine of the Central European tectonics, in the southwest to the rigid, aseismic European Platform in the north-east one regional and several smaller scale geodynamic networks have been measured since the early 1990s using the Global Positioning System (GPS) space geodetic technique. A continental permanently observing GPS network has also been providing data since the mid 1990s, and there are several stations of the global networkin the region as well. After almost a decade, some of these networks have already produced intraplate velocity solutions In general, the site density of these networks is in inverse proportion to the covered area, thus an adequately dense velocity data at a regional level, required by the complex crustal structure, and highly interconnected tectonic processes, can only be achieved by the integration of the results of these networks Our goal is an integr ated dense intr aplate crustal velocity field for the better under standing the present tectonics of the region.
