Determination of the Active Tectonics of Siirt City and Its Surroundings in the Bitlis-Zagros Suture Zone Foreland Using Geomorphological Data
Abstract
Siirt and its surroundings are in the foreland of the Bitlis-Zagros Suture Zone (BZSZ), a prominent neotectonic structure formed by the collision of the Arabian and Eurasian plates. However, studies focusing on the tectonic features of this foreland region near the BZATZ are limited. This study aims to investigate the effects of active tectonism in Siirt and its surroundings, situated within BZATZ, using geomorphological data, and to identify the active faults in the region. Geographic Information Systems (GIS) technologies and geomorphological analysis methods were applied during the evaluation process. The results reveal significant variations in slope values over short distances, reflecting the influence of active tectonics in and around Siirt. A range of tectonically induced landforms have developed, including hanging valleys, fault scarps, landslides, terraces, linear valleys, offset streams, alluvial fans, shutter ridges, and pressure ridges. Both right-lateral and left-lateral strike-slip faults were identified. The right-lateral faults are interpreted as the southward continuation—within a broad deformation zone—of the Kozluk-Narlı Fault described by Perinçek et al. (1987). These faults, which have caused notable deformation and stream offsets, are referred to in this study collectively as the “Kozluk-Narlı Fault Zone.” Future research should focus on delineating the boundaries, geometry, and active tectonic characteristics of this fault zone beyond the current study area. Many of the previously identified active faults in the Siirt region, near the BZATZ, appear incomplete.
