GNGTS 2018 - 37° Convegno Nazionale

GNGTS 2018 S essione 1.2 225 maintain and develop the Central European GPS Geodynamic Reference Network (CEGRN network). Nowadays CEGRN collects, processes the GNSS observations from standard RINEX files (IGS, RINEX format) and combines the normal equations, in-house produced as well as delivered by other Analysis Centres (ACs) in standard SINEX (IERS, SINEX format ) format. CEGRN analyses the results, produces derived geophysical products from the velocity field, and encourages the collaboration of Research Institutions. The resulting positions and velocity field, among other products, resulting from all these activities are made available through the CEGRN website, presently hosted and maintained by the University of Padova. The main objective of the CEGRN network is the monitoring of crustal surface deformations by analysis of GPS, now GNSS (GPS and Glonass), measurements of regularly scheduled campaigns. The results of the first phase (1994-1997) are discussed by (Grenerczy et al. , 2000). High density 3D velocities and strain rate fields are derived as the basis for geodynamic investigations (Becker et al. , 2002). The main study areas cover the Adriatic Microplate, the Balkan and Dinarides, the CarpathianArc, the EasternAlps and the Pannonian Basin, all of them active tectonic zones. The long term project is running since 1994 and was sponsored twice by EU projects: CERGOP1 and CERGOP-2 (Environment Central European Geodynamics Project, funded by the European Union from 2003 to 2006) under the 5th Framework Programme (Fejes, 2002; Fejes and Pesec, 2003). Fig. 1 - Simplified tectonic map of the CEGRN area. The black and blue lines indicate respectively the top trace of the normal and reverse and strike slip faults from the Euro-Mediterranean database of seismogenic sources (SHARE project, Basili et al. 2013). The thick black lines show the principal tectonic structures in the study area. AlCaPa = Alpine–Carpathian–Pannonian terrain; EA = Eastern Alps; E. Carp. = East Carpathians; MHZ = Mid Hungarian Zone; MMZ = Mur-Murz-Zilina line; PB = Pannonian –Basin; PAL = Periadriatic lineament or Pustertal Gailtal fault system. S. Carp. = South Carpathians; TESZ =Trans European Suture Zone; TD= Tisza-Dacia unit; TW = Tauern Window.; W. Carp. = West Carpathians; WM = Wallachian-Moesian region.
