“…The most recent moderate earthquake (5.9 Mw) occurred on the faults of the NAFZ cropping out along the Karlıova District on 14 June 2020 (AFAD, 2021;KOERI, 2021). These moderate earthquakes are not capable of releasing the strain accumulated in the NAFZ in Bingöl (Akbayram et al, 2022b). Previously, the faults of the NAFZ in Bingöl are reported as seismic gaps (Sançar et al, 2009;Zabcı et al, 2017).…”

“…In 2005 and 2020, the maximum 1≤M<3 earthquake number and the maximum 1≤M earthquake magnitude (5.9) was measured in the Karlıova District. The increase in earthquake numbers in these years can be explained by the occurrence of aftershocks of 12-14 March 2005 (5.7 Ml and 5.9 Ml respectively) (Demirtaş, 2019;KOERI, 2021), and 14 June 2020, 5.9 Mw (Akbayram et al, 2022b;AFAD 2022;KOERI 2022) events. In the Yedisu District, 1 ≤ 𝑀𝑀 < 3 earthquake number is maximum as in Karlıova District.…”

This study discusses the temporal distribution of earthquake magnitudes in the city of Bingöl, near Karlıova Triple Junction. We determine the probability distributions and return periods of earthquakes for all districts of Bingöl. Bingöl has eight districts; namely Adaklı, Central, Genç, Karlıova, Kiğı, Solhan, Yayladere, and Yedisu. In six of them, active faults were mapped previously (Adaklı, Central, Genç, Karlıova, Solhan, and Yedisu). We consider 5 time-dependent probability distributions for analysis. Using the annual maximum earthquake magnitudes, the best fit arises from the Gumbel distribution for Central, Karlıova, and Adaklı Districts. For the Genç District, where the least maximum earthquake magnitude is reported, the Weibull distribution gives the best fit. The return period and maximum annual earthquake magnitude relations suggest the following results. For the Central and Karlıova Districts along which maximum earthquake magnitudes are reported, every 250 years a 6.7 M, and 7.2 M occurs respectively. These results are compatible with the results of paleo-seismological data reported along the NAFZ and the EAFZ. For a 10-year return period, earthquake magnitudes reach 3.9 and 5.1 in all districts. It is important to note that in the Yedisu District, the maximum earthquake magnitudes seem as 5.1 M for the 1000-year return period, incompatible with previously published findings probably because low quality seismic data in this region.
