“…The velocity field and strain fields are characterized by a system that indicates non-deforming and deforming regions separated by fault zones. In addition, the velocity field is in agreement with location of seismicity, earthquake focal mechanisms, and mapped fault locations, as supported by former studies [30,2,7]. The southern part of the area shows slower movement than the north, according to GPS velocity vectors.…”

Southwestern Turkey is a tectonically active area. To determine kinematics and strain distribution in this region, a GPS network of sixteen stations was established. We have used GPS velocity field data for southwest Anatolia from continuous measurements covering the period 2003 to 2006 to estimate current crustal deformation of this tectonically active region. GPS data were processed using GAMIT/GLOBK software and velocity and strain rate fields were estimated in the study area. The measurements showed velocities of 15–30 mm/yr toward the southwest and strain values up to 0.28–8.23×10−8. Results showed that extension has been determined in the Burdur-Isparta region. In this study, all of strain data reveal an extensional neotectonic regime through the northeast edge of the Isparta Angle despite the previously reported compressional neotectonic regime. Meanwhile, results showed some small differences relatively with the 2006 model of Reilinger et al. As a result, active tectonic movements, in agreement with earthquake fault plane solutions showed important activity.

The present kinematics in the eastern Mediterranean and Middle East is now well constrained by GPS measurements and dominated by a circular counterclockwise motion. While Arabia rotates rigidly, the rotational velocities increase from the Levant to Aegea, causing extension in western Anatolia. We place the present pattern in light of the post–Middle Miocene geological history and propose that in addition to the effects of the Hellenic subduction and Zagros collision-subduction zones on driving the surface motion, an underlying asthenospheric flow is also required. This counterclockwise toroidal flow is expected to exist around the eastern edge of the African slab owing to subduction rollback, and it helps explain the initiation of the North Anatolia Fault, the extrusion and uplift of Anatolia, and the Mid-Miocene to Recent volcanism in eastern Anatolia. The Afar plume had a similar effect on the acceleration of Arabia at 40 Mya.
