Abstract

Most of the Turkey is located in the earthquake affected region in the World due the its position. According to AFAD referenses, 42% of Turkey's land is on the first-degree earthquake zone. In that region, Northwest Anatolia and the North Aegean Sea are among the most important active seismic and deformation zones which are located between the Eurasian and African tectonic regions. According to Kandilli Observatory data, a moderate-intensity earthquake (Mw=5.3) occurred on 06 February 2017, at Gulpinar-Ayvacik (Canakkale) center, at 06: 51 local time. The depth of focus of the earthquake is about 6 km and it is a shallow-focused earthquake. In this study, the situation of the rural traditional masonry structures which are affected by the earthquake mentioned in the region, was examined and analyzes on the causes and results of damage were developed. Researches show that, Yukarikoy is the village where mostly affected from different size earthquakes in the following days. The traditional masonry stone structures in this region also reflect the characteristic form of the zone, architectural features and construction technique. The purpose of the study is to establish the cause and effect relations of the damage by determining the damage of the structures which have been significantly affected from the earthquake in Yukarikoy. AFAD and the relevant official institutions criteria were used to determine the damage level of the buildings. The results show the cause of the damage and the magnitude of the risk that it creates on the structures.
