The CERGOP2 project funded by the European Union from 2003 to 2006 under the 5th Framework Programme benefits from repeated measurements of the coordinates of epoch and permanent GPS stations forming the CEGRN network in Central Europe, starting 1994. We report on the results of the systematic processing of the available data up to 2005. The analysis work has yielded the velocities of some 60 sites, covering a variety of Central European tectonic provinces, from the Adria indenter to the Tauern window, the Pannonian basin, the Vrancea Seismic Zone and the Carpathian Mountains. The estimated velocities define kinematical patterns which outline, with varying spatial resolution depending on the station density and history, the present day tectonic flow in Central Europe.The CEGRN data show that the majority of active contraction originating from the Eurasia Nubia plate boundary and the microplate between them is taken up primarily in the Eastern Alps, the Dinarides, and the Pannonian Basin. After removal from the ITRF2000 velocities of a rigid rotation accounting for the mean motion of stable Europe, the residual velocities have random orientations with 0.3 mm/yr scatter. This Iow figure provides an upper estimate for the level of rigidity of the European Platform. A 2.3 mm/yr north-south oriented convergence rate is implied by our data between Adria and the Southern Alps, and a narrow - -60 km wide- contraction zone in the Southern Alps is identified, consistently with earlier results. An eastward extrusion north of the contraction zone corresponds with the extension of the Tauern Window. In the southeastern boundary of the microplate, 4-4.5 mm/yr motion of Adria decreases to -1 mm/yr through the microplate, its boundary, and the Dinarides mountain range towards the southwestern part of the Pannonian Basin. Our data suggest that if the Pannonian Basin is subject to deformation, then it is most likely to be compressional than extensional. We conclude that compression and associated contraction due to the Adria collision with the Alps and the Dinarides is likely to fade away in the Western and Northern Carpathians, where our velocities and strain rates show no significant deformation.

This paper summarizes the recent works with respect to the CERGOP-2 project tasks. The main activity was the implementation of the Working Package "Geodynamics of Balkan Peninsula". Major efforts were taken to the maintenance of the operation of two permanent GPS stations in Bulgaria and to arrange for the data transmission to the CERGOP Data Centre in Graz. The CEGRN GPS campaigns of 2003 and 2005 were analyzed together with additional Balkan Peninsula stations. New results on coordinates and velocities for this Balkan Peninsula subnet of CEGRN are computed and will be presented and discussed. The accomplished works on the monograph "Geodynamics of Balkan Peninsula" with the preparation of the manuscripts and the main content of the findings will be outlined.

Moreover it is emphasized on the results not presented at the previous conferences of the project up-to-now or related to it. Processing, comparison and analysis of the GPS campaigns (BULREF'93 -BULREP03/CEGRN'03), of data from the permanent stations located on the Balkan Peninsula and of CEGRN, EUREF and other stations have been accomplished. The organisation and results from the activity of the Balkan's partners participating in the project realization have been presented. Respective suggestions, main aspects of the follow-up investigations and conclusion have been outlined.

One of the main objectives of the second phase of the Project CERGOP-2 (Central Europe Regional Geodynamics Project) is to continue studies on geotectonic regions of Central Europe. A special study group CSG.5 "Geotectonic analysis of the region of Central Europe" was established in 1999 to coordinate the geodynamic research in the frame of the project CERGOP. There are several groups of scientists carrying out the research on particular regions of Europe. A spectacular evident achievement of such a work within the second phase of the Project CERGOP-2 was the publication of two volumes of geotectonic monographs on two Bulgarian regions Krupnik-Kresna and Chirpan-Plovdiv related to the earthquakes occurred in 1904 and 1928. The monographs were published in 2000 in the series REPORTS ON GEODESY edited by the Institute of Geodesy and Geodetic Astronomy of the Warsaw University of Technology Poland. This is the nice example of joint work of Bulgarian scientists -geodesists, geologists and geophysicists. The paper contains a short outline of the new organisation of geodynamic research within the project CERGOP (Central Europe Regional Geodynamics Project) and the contents of both Bulgarian monographs.
