Recent tectonic activity in the Eastern Sudetes and on the fore-sudetic block on the basis of 1993-2003 investigations

The characteristics of geodynamic investigations in the Eastern Sudetes and the Fore-Sudetic Block region during the 1993-2003 period are presented. The investigations included repeated GPS, gravimetric and other observations realized in three local research areas and a regional network. The local research networks have been integrated into the regional network through selected points. The regional network has been connected to the permanent stations network EPN/IGS. This has allowed calculation of the points' velocities in a uniform reference frame ITRF2000. The calculated movement parameters of points have been the basis for estimating the kinematics of tectonic structures including gravity changes. The results have confirmed recent activity of the young tectonic structures in research region.
