Özet

An earthquake, a moment magnitude of 5.0 (M-w), occurred on 10 January 2016 at 19.40 local with its epicenter, Hacidurakli, the village of Cicekdagi, Kirsehir in Central Anatolia that was known as a seismically quiet region. Its focal mechanism solution showed a right-lateral strike-slip faulting. This indicated that the earthquake occurred in WNW-ESE trend segment of Manahozu Fault that was right lateral strike-slip fault, consisted of two structural segments and complied with the focal mechanism of the earthquake. Manahozu Fault is active and one of the most important structures that play a role in shaping the region. Seyfe Fault Zone NW-SE trend right-lateral strike-slip fault is one of the most significant geological structures in Kirsehir and its near surroundings. The interaction between these active structures caused the occurrence of Seyfe pull-apart basin. Besides, it is thought that the rise in the northern part of the Manahozu fault may occur due to the convergence between Manahozu Fault and Yerkoy Fault Zone. NW-SE trend segment of Manahozu Fault, an active structure, is also evaluated as a structure that has a potential to create earthquakes in future.
