Uniaxial Deformations Estimation in the Vrancea Area Based on GPS Data

The present paper aims to analyze the state of crustal deformation in the Vrancea area using GPS measurement data. Unlike previous approaches that used station networks, uniaxial deformations method on profiles has now been used. A brief description of the extended Vrancea network was made, whose nodes were used to draw the measurement alignments. For each subnet Northern Vrancea and Southern Vrancea respectively, separate alignments were drawn, the analysis being carried out for each subnet separately. The analysis takes into consideration 21 alignments, 8 in the Northern Vrancea subnet and 13 in Southern Vrancea subnet. The results are presented in the form of result tables, in which the uniaxial strains and the variation of the angle with respect to the North direction at the two moments of the determinations, t1 and t2 were determined. For each measurement alignment, a graphic representation that contains all the calculated elements was made. The conclusions refer to the characteristics of the two subnets in terms of calculated values, to the strain magnitudes and to their possible connection with the local fault system.
