TI  - Determining the main strand of the Eskişehir strike-slip fault zone using subsidiary structures and seismicity: a hypothesis tested by seismic reflection studies
AB  - The Eskişehir Fault Zone is one of the major neotectonic structures of Turkey, extending from İnegöl (Bursa) to Cihanbeyli(Konya). The fault zone presents a considerable seismic risk for the city of Eskişehir but the exact locations of active segments and thesource of the major seismic event, the 1956 earthquake (M = 6.5) that occurred in the instrumental period (from 1900 to 2013), havebeen debated in recent literature. The structural data obtained from field studies indicate an approximately N60W-trending main strandof the right lateral strike-slip Eskişehir Fault Zone. This trend corresponds to the en echelon bends on the course of the Sarısu River.Using this concurrence, the positions of Bahçehisar and the Çukurhisar-Sultandere segments are proposed and checked by seismicreflection studies. The seismic sections disclosing positive flower structures confirm the hypothesized position of the Çukurhisar- Sultandere segment. The relocation of epicenters and focal mechanism solutions of seismic events in 1956, 1990, 2010, and 2013 indicatethat the Çukurhisar-Sultandere segment might be the rupture source of the 1956 event and is a possible potential seismic source for anearthquake that could seriously affect the Eskişehir settlement.
