In this study, an active fault database in ArcGIS format is prepared as part of an international project, namely Earthquake Model of Middle East (EMME) Project for Turkey and surrounding regions. The active fault database is prepared for fault segments that may generate earthquakes with moment magnitude greater than 5.5. Fault sections are defined as part of a fault segment where at least one fault parameter (strike, dip, rake, seismogenic depth) is changed. The active fault database consists of 36 columns of entries such as fault length, strike, dip, rake, dip direction, slip rates, slip type etc. for each individual fault section. The entries also include the reference codes from which the parameters have been retrieved and compiled. Separately full references were given in a relational database. Additionally a digital library containing electronic files of the references is also compiled. In total, 1070 fault sections have been defined, having a total fault length of 23.356 km. In the second part of the study, the study area has been divided into 54 earthquake source zones. Using a seismicity catalogue (Kalafat et al., 2011) covering the time period 1900-2010 seismiciy parameters have been computed for each source zone. The b values of Gutenberg-Richter equation vary between 0.6 and 1.4 in Turkey. The computations have suggested that the North Anatolian and East Anatolian Fault Zones, the Aegean subduction zone, the western Cyprean subduction zone are the areas with the most notable seismic energy release

Türkiye ve Yakın Çevresinin Aktif Fayları Veri Bankası ve Deprem Tehlikesinin Araştırılması

Öz

Bu çalışmada Türkiye ve yakın çevresinin aktif fayları Uluslararası Ortadoğu’nun Depremsellik Modeli (EMME) projesinin bir alt çalışması olarak sayısallaştırılmış, coğrafi bilgi sistemi tabanlı ArcGIS yazılımı kullanılarak en güncel verilerden oluşan bir veri bankası hazırlanmıştır. Çalışmada aktif faylar segmentlere, segmentler de magnitüdü Mw≥5.5 olan depremleri üretme potansiyeline sahip olduğu bilinen fay kesmelerine bölünmüştür. Aktif faylar veritabanı her bir segment için 36 veri girdisi içermekte olup önemli fiziksel parametreler (fayın uzunluğu, doğrultusu, eğimi, sapma açısı, eğim yönü, kayma hızı vs.) tanımlanmıştır. Türkiye için aktif faylar veri tabanında 1070 adet ‘’fay kesmesi’’nin fiziksel parametreleri tanımlanarak, 23356 km uzunluğunda ‘’fay kesme’’lerinin parametre girişi yapılmıştır. Her fay kesmesi için elde edilen fiziksel parametrelerin kaynakları (makale, rapor, harita vb.) belirlenmiş bir formatta bir araya getirilerek, pdf dosyalarından dijital bir kütüphane hazırlanmıştır.İkinci aşamada ise Türkiye ve çevresi için çalışılan alan 54 adet deprem kaynak zonuna bölünmüş ve deprem tehlike haritaları oluşturulmuştur. Kandilli Rasathanesi Deprem Araştırma Enstitüsü’nden temin edilen 1900-2010 yılları arası homojen deprem kataloğu (Kalafat ve diğ., 2011) kullanılarak, her bir zon için depremsellik parametreleri hesaplanmış elde edilen b değerlerinin genellikle 0.6-1.4 arasında değiştiği görülmüştür. En çok enerji açığa çıkaran bölgeler Türkiye’de Kuzey Anadolu Fay Zonu, Doğu Anadolu Fay Zonu, Ege yayının doğusu, Güney Marmara ve Kıbrıs yayının batısında tespit edilmiştir
