Özet

Izmir and its surroundings constitute an important tectonic region for the control of the Western Anatolian region. The study area is located in the western part of Izmir city and inside of Karaburun Peninsula. In the study area and its surroundings, a great amount of earthquakes occurred in both land and sea in recent years. Hence, the kinematic structures of Gulbahce fault and Uzunkuyu intrusive were examined within this study. As a first step, the mechanism and the velocities of these faults were identified using the GNSS data. Then, a stress and strain analysis of the region was performed for different depths using Coulomb software. In this study, the strain changes on vertical direction were evaluated and compared with the changes of observed gravity anomalies for the first time for the study area as distinct from the previous studies. From this integrated analysis, we retrieved the kinematic parameters and movement mechanisms of Gulbahce fault and Uzunkuyu intrusive and defined the regional stresses, the strain changes and the kinematic models of them.
