Crustal Structure of the Eastern Anatolia Region (Turkey) Based on Seismic Tomography

Here, we investigated the crustal structure beneath eastern Anatolia, an area of high seismicity and critical significance for earthquake hazards in Turkey. The study was based on local tomography method using data from earthquakes that occurred provided by Turkiye Cumhuriyeti Ministry Interior Disaster Emergency Management Directorate Earthquake Department dataset used included travel times 54,713 P-waves 38,863 S-waves 6355 seismic events. distributions resulting velocities (Vp, Vs) down to a depth 60 km demonstrate significant anomalies associated with major geologic tectonic features region. Arabian plate revealed as high-velocity anomaly, low-velocity patterns north Bitlis suture are mostly Anatolia. upper crust Anatolia ~10 thick anomaly; lower is wedge-shaped anomaly. This kind under corresponded hypothesized existence lithospheric window this collision zone, through which hot material asthenosphere rises. Thus, presented results help clarify deep
