![]() Finally, the upward continuation was applied to Tyy, Tyz and Tzz tensors up to 20 km. These depth values are consistent with the depth values of the structural discontinuities obtained from previous studies. Also, the mean depths of the possible structures were calculated by the power spectrum method at four profiles taken from gravity disturbance data. New possible discontinuities have been identified in the tensors and some of the obtained discontinuities were clarified in their previous discussions. The tensor and invariants of this gravity disturbance data were first calculated. In the case application stage, the gravity disturbance data obtained from the Earth Gravitational Model of the eastern of the Aegean Sea and western of Anatolia were evaluated. In addition, the mean depths of these structures were determined using the power spectrum method. Likewise, when the Txx, Tyy components and invariant results are examined, the vertical and horizontal boundaries were successfully obtained. When the results are examined, it is observed that the Tzz tensor component gives very clear information about the location of the structure. Within the scope of the theoretical study, a single model and three bodies model were taken into consideration. These methods were tested initially on theoretical data. Various boundary analysis methods were applied to the gravity disturbance data to compare the discontinuities obtained from the tensors both theoretical and case study. It is thought that the gravity disturbance data reflects the tectonic elements and discontinuities way better than gravity anomaly due to the calculation from the difference between gravity and normal gravity at the same point so thus the tensors and invariants of the study area were calculated and the power spectrum method was applied to the gravity disturbance data. ![]() To evaluate these tectonic elements gravity disturbance data of the Aegean Sea and Western Anatolia was used in this study. The borders of the Aegean Sea tectonic is limited between eastern of Greece, western of Anatolia and Hellenic subduction zone in the south of Crete. Western Anatolia has been shaped N-S-trending extensional tectonic regime and W-E trending horst, grabens and active faults due to the collision of Africa, Arabian and Eurasia plates. Obtained deformation analysis results and the relationship between tectonics were interpreted together. Extension, shortening, dilatation and rotation maps of the study area were performed. The deformation analysis of the Eastern Mediterranean, which is a larger area, was firstly carried out, and then the area was reduced and the regional results of Cyprus and its surroundings were tried to be reached. Deformation analysis was performed for three different areas by using GPS velocities of previous studies. In order to be able to examine the tectonic elements in the region, analysis was done in three stages. ![]() Eastern Mediterranean, which has a very active tectonism, was chosen as study area within the scope of this study. Deformation, which is the gradient of the displacement field, can be calculated by using GPS displacement vectors obtained from the measurements made in the interplate and plate boundaries and reveals important information about regional tectonics. With the developing technology and data processing techniques, GPS can be used to determine the related/relative position and velocity of a point in millimeter accuracy. Global Positioning System (GPS) is an advanced method for determining horizontal and vertical displacement.
