 Abstract: This work presents an analysis of dynamic displacements observed on GNSS stations in the Aegean region, induced by the two earthquakes with magnitude 7.8 and 7.5, in Southern Turkey on 06/02/2023. For this reason, GNSS data of 1Hz observation rate from continuously operating stations located across the Aegean Sea and the mainland of Greece was processed using Precise Point Positioning method. Position time-series were analyzed to estimate the amplitude of the displacement, the direction in which the maximum displacement is observed and the time of occurrence. Furthermore, emphasis is given on comparing the characteristics of the displacements observed between the two events and examine a possible correlation with the corresponding faults’ geometry for each separate event. An additional evaluation of the kinematic behavior of permanent GNSS stations located in proximity of the Hellenic subduction zone with the African plate, the latter sharing a tectonic boundary with both the Arabian and Anatolian plates was conducted. The results of this work discuss the effects that strong earthquakes can have at distances over 1000 km and along active tectonic boundaries, implying the larger-scale impact of such geohazards.
