Turkey has a high
earthquake risk due to include the active North Anatolian Fault Zone (NAFZ) and
East Anatolian Fault Zone (EAFZ). The earthquakes should be detail investigated
in order to minimize the damage caused by the earthquakes. Different
statistical approaches are used in these estimation studies. Poisson
distribution model is widely used in earthquake studies. The model used for a
large number of statistical studies and it gives reliable results. Moreover,
exponential distribution model is used in earthquake prediction studies. In
this study, EAFZ and its near regions were selected as the study area. The
Poisson and Exponential distribution model was applied by using the earthquakes
of Ms≥5.0, which occurred in the selected area between 1900 -2016. The
probabilities of occurrence of earthquakes with a magnitude of Ms≥5.0 and
recurrence periods are calculated with the obtained model results. According to
the results of Poisson model, the probability of earthquake (Ms≥5.2) within 1
year is 33,6% and earthquake recurrence period is estimated as 2 year.
According to the exponential distribution model results, the recurrence of earthquakes
(Ms≥5.2) is 1 years and probability is74,7%. The two models were compared and
the results were evaluated. When the seismicity of the region was examined, it
was seen that the results were consistent.

Türkiye
içerdiği aktif Kuzey Anadolu fay zonu (KAFZ) ve Doğu Anadolu fay zonu (DAFZ)
nedeniyle yüksek deprem riskine sahiptir. Depremlerin yaratacağı hasarların en
aza indirilmesi için depremlerin önceden tahmini üzerine araştırmalar
yapılmalıdır. Bu tahmin çalışmalarında farklı istatiksel yaklaşımlar
kullanılmaktadır. Deprem çalışmalarında literatürde yaygın olarak Poisson
dağılım modeli kullanılmaktadır. Çok sayıda istatistiksel çalışmada kullanılan
model güvenilir sonuçlar vermektedir. Ayrıca üstel dağılım modelinde deprem
tahmin çalışmalarında kullanılmaktadır. Bu çalışmada DAFZ ve civarı inceleme
alanı olarak seçilmiştir. Seçilen bölgede 1900- 2016 yılları arasında meydana
gelen Ms≥5.0 depremler kullanılarak Poisson ve Üstel dağılım modeli uygulanmıştır.
Elde edilen sonuçlarla büyüklüğü Ms≥5.0 olan depremlerin olma olasılıkları ve
tekrarlama periyotları hesaplanmıştır. Poisson modeli sonuçlarına göre büyüklüğü
1 yıl içinde deprem (Ms≥5.2) olma olasılığı %33,6 ve deprem tekrarlama periyodu
2 sene olarak hesaplanmıştır. Üstel dağılım model sonuçlarına göre büyüklüğü  (Ms≥5.2) 
bir depremin tekrarlama periyodu 1 yıl ve olasılığı %74,7 olarak
belirlenmiştir. İki model karşılaştırılmış ve sonuçları değerlendirilmiştir.
Bölgenin depremselliği incelendiğinde sonuçların tutarlı olduğu görülmüştür.
