The area of western border of the CEI member countries is created by different geological structures as a part of Easter Alps, Carpathians, Pannonian Basin, Bohemian Massif and eastern area of Polish platform. This area includes northern slopes of the Alps, their foredeep and contact with the Bohemian Massif, West Carpathians foredeep towards Bohemian Massif and a part of Polish platform, crossing area of Sudeten fault zone and T-T zone. The entire territory is covered by map of annual velocities of vertical movements as well as by network of GPS stations. In present paper the geodynamical properties of mentioned above territory are analysed and shortly discussed both in vertical and horizontal component. It should be added that the vertical movements are derived from repeated levelling performed before and after the World War II and 1995. The horizontal component is derived from satellite (GPS) measurements after 1994 (see Fig. 1).

Looking at the geologic map (Fig.l) and the geotectonic division (inside scheme of Fig.l) of Europe we can see, that the area investigated by the 7 groups for regional investigation (WP 10.1 to WP 10.7) of the CERGOP - 2 work package WP 10 "Geodynamics of Central Europe" (see tab. 1 for subjects and chairs) belong almost exclusively to the Alpine Europe, called also Neo-Europe. More exactly it belong: to the Eastern Alps-Carpathian-Balkan of the northern and the Dinaric Alps of the southern branches, of the European sector of the Alpine-Himalayan erogenic belt, with the Pannonian Basin in between. The forefield of the Eastern Alps-Carpathian-Balkan Alpine fold-and-thrust belt is very heterogenous and comprise tectonic units of Hercynian (e.g. Bohemian Massif of Czech Republic including the marginal Sudetic structures of Poland), Caledonian (e.g. within the Transeuropean Suture Zone - TESZ - of Poland), and Precambrian (Podole-Moldavian sectors of the East-European Platform of the Ukraine and Romania). These were described in great details in a series of monographs published in Reports on Geodesy by the Chief Editor J. Sledzinski as results of the CERGOP-1 Study Group CSG 8 "Geotectonic analysis of the region of Central Europe".

The report contains the description of monitoring of recent crustal movements in the European region covered by the CEGRN stations with highlighting the geologic, geophysical and geodetic aspects of studies carried out by European scientific institutions. The report includes the information coming from different sources and in particular from studies performed by the CERGOP-2/Environment workpackage sub-groups WP10.1 - WP10.7. These sub-groups currently arrange, plan and organise programmes of their activities in particular regions in a fully independent, self-determining and "sovereign" way. So the report will be currently updated by the results of investigations of the sub-groups WP10.1-WP10.7. Since all chairmen of workpackages are obliged to report their activities at the EGU-CEI symposia in April every year it is expected that the three main inputs of new results of investigations will be available in April 2004, April 2005 and April 2006. The chairmen of workpackages have also to concisely report the activities of their sub-groups at the CERGOP-2 Working Conferences that will be organised every year in fall time. So, also a short updating of the Pilot Report will probably be possible after the CERGOP-2 fall conferences.

Long borderline between Poland, Czech Republic and Slovakia coincides generally with very interesting geotectonic formations of different age that give an excellent opportunity to undertake a comparative studies that have a significant scientific and practical value. The main general objective of the Project is to investigate the variations of the recent crustal movements and periodic monitoring of the horizontal and vertical displacements in the structural active tectonic zones of the Polish and Czech parts of the Sudetes Mts. and the Western Carpathians as well as in the regions located close to the existing and planned investments and technical constructions (water reservoirs and dams, power stations, communication lines, etc.). In the Tatra Mts., that represent the youngest tectonic formation of the area of Central Europe, the tectonic movements and relativety significant velocity vectors will be monitoring as well as the location of the geoid (the quasi-geoid) related to the geocentric reference ellipsoid will be determined. The established test control networks in Sudetes Region and in Tatra Mts. will be used by Polish, Czech and Slovak geodesists and surveyors for testing new technologies and upgrading the practical quick methods of satellite and geodetic positioning procedures applicable for geodesy and navigation, in particular in hilly and mountainous areas. The project will be realised in the frame of the CEI CERGOP Study Group CSG.5 "Geotectonic analysis of the regions of Central Europe". 1.

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.
