Within CERGOP-2/ENVIRONMENT project, a special attention is given to geodynamics models development for specific regions from countries that participate to the present project. For this goal, study groups were created (WPs-l0.x) which has the main objectives to monitor recent crust movements, to detect the borders of the tectonic plates and to quantify their three dimensional movement rates. These studies require a close cooperation between geodesists, geologists and geophysicists. In 1996 the Collaborative Research Center (CRC) 461 "Strong Earthquakes: A Challenge for Geosciences and Civil Engineering" was founded by the Deutsche Forschungsgemeinschaft (German Research Foundation) as a German contribution to the UN initiative "International Decade of Disaster Reduction" (IDNDR). A central project, of this CRC, is the subproject BI "Three Dimensional Plate Kinematics in Romania", which studies the deformation determination ofgeotectonic units in the Vrancea Region (epicenter zone of earthquakes from Romania). In this purpose, there were accomplished by repeated GPS-measurements within a network which has been installed in 1997 - Fig. 4 (Ghitau, 1997, Dinter & Schmitt, 1999, et al.) and measured in 1997, 1998, 2000, 2002 and 2003. This network was formed, at the beginning, by 26 stations, covering an area of 250 km x 380 km having the Vrancea area as the centre. At present, the studied region is enlarged to southern part of Romania and contains much more points. The geodetic DATUM is given by stations of the CEGRN the CEI-initiative CERGOP.
