Özet: Akşehir Graben, one of the most important depression areas of SW Anatolia, is one of the regions where seismic activity is most intensely developed today. The Akşehir Graben extending in a NW-SE direction in the region is located in the eastern part of the Sultandağı elevation. The Akşehir Graben is bounded by the Akşehir Fault in the south. The Akşehir fault is the most important segment that forms the southern part of the Akşehir-Simav Fault Zone and is still active today. The Akşehir Fault, which extends in the N55 W direction in the study area, is a normal-slip fault separating the Sultandağı metamorphic massif and the alluvium filling the Akşehir graben. Alluvial fan sediments and accumulation cones and accompanying slope debris are commonly found along the Akşehir Fault on the southern edge of the Akşehir Graben, which extends in a NW-SE direction. In addition, fault scarp, breccia zones and hydrothermal alteration zones that can be observed laterally in the topography are other important structural features that can be widely observed on the Akşehir Fault Zone. The Akşehir Graben and the Akşehir Fault that limits it have a seismic regime in which mostly medium-sized earthquakes occur. In this study, the earthquake activity of the region will be examined based on the earthquakes in the historical and instrumental period.
