Özet:

 Hakkari, Türkiye, is one of the most active provinces of the Southeast Anatolian Region in terms of seismicity and tectonism. During the instrumental and historical period, these fault systems in the Hakkari region have produced many destructivedamaging earthquakes. The earthquakes that occurred in December 2023 Mw4.7 and February 2024 Mw4.3 in recent years are important indicators of current seismicity in this region. According to the results obtained from the analyses, the average b-value in the study region is 0.880.09 and the lowest b-values are observed around the Yüksekova-Şemdinli Fault Zone. In addition, positive Coulomb stress changes have been observed in and around Hakkari in NW-SE and NE-SW directions. On the other hand, the return period of an earthquake with a magnitude of Mw5.0 for the selected region is 16 years. Also, the occurrence probabilities of an earthquake with a magnitude of Mw5.0 in 10, 16 and 20 years is calculated as 45, 62 and 69, respectively. In conclusion, the current seismic hazard potential of Hakkari province and its surroundings has been revealed with the combination of seismotectonic parameters calculated in this study.

 Hakkari Türkiye, depremsellik ve tektonizma olarak Güneydoğu Anadolu Bölgesinin en aktif illerinden bir tanesidir. Aletsel ve tarihsel dönemde, Hakkari ili ve civarında bulunan bu fay ve fay zonları birçok yıkıcıhasar verici deprem üretmiştir. Son yıllarda Aralık 2023 Mw4.7 ve Şubat 2024de Mw4.3 meydana gelen depremler, bu bölgedeki güncel depremselliğin önemli göstergelerindendir. Analizlerden elde edilen bulgulara göre, bölgede ortalama b-değeri 0.880.09 olup en düşük b-değerleri Yüksekova-Şemdinli Fay Zonu civarında gözlenmiştir. Buna ek olarak, pozitif Coulomb gerilme değişimleri Hakkari ili ve civarında KB-GD ve KD-GB yönlü olarak ortaya çıkmıştır. Diğer taraftan, seçilen bölge için Mw5.0 büyüklüğündeki bir depremin tekrarlama zamanı 16 yıldır. Ayrıca, Mw5.0 büyüklüğündeki bir depremin 10, 16 ve 20 yılda oluşma olasılıkları ise sırasıyla 45, 62 ve 69 olarak hesaplanmıştır. Sonuç olarak, bu çalışmada hesaplanan sismotektonik parametrelerin birlikte değerlendirilmesi ile Hakkari ili ve civarının güncel sismik tehlike potansiyeli ortaya çıkarılmıştır.
