10 January 2015 Hacıduraklı-Çiçekdağı (Kırşehir) earthquake (Mw = 5.0); implications about related structures and tectonic environment, Central Anatolia - Turkey

Abstract: An earthquake, a moment magnitude of 5.0 (Mw), occurred on 10 January 2016 at 19.40 local withits epicenter, Hacıduraklı, the village of Çiçekdağı, Kırşehir in Central Anatolia that was known as a seismically quiet region. Its focal mechanism solution showed a right-lateral strike-slip faulting. Thisindicated that the earthquake occurred in WNW-ESE trend segment of Manahözü Fault that was rightlateral strike-slip fault, consisted of two structural segments and complied with the focal mechanismof the earthquake. Manahözü Fault is active and one of the most important structures that play a rolein shaping the region. Seyfe Fault Zone NW-SE trend right-lateral strike-slip fault is one of the mostsignificant geological structures in Kırşehir and its near surroundings. The interaction between theseactive structures caused the occurrence of Seyfe pull-apart basin. Besides, it is thought that the rise inthe northern part of the Manahözü fault may occur due to the convergence between Manahözü Fault andYerköy Fault Zone. NW-SE trend segment of Manahözü Fault, an active structure, is also evaluated as astructure that has a potential to create earthquakes in future.
