Evolution of seismic hazard maps in Turkey

Abstract: A review on the historical evolution of seismic hazard maps in Turkey is followed by summarizing the important aspects of the updated national probabilistic seismic hazard maps. Comparisons with the predecessor probabilistic seismic hazard maps as well as the implications on the national design codes conclude the paper.

“…Seismic risk assessments have been made in previous studies (e.g. Demircioğlu et al, 2017;Akkar et al 2018) and the region between the NEAF and the NAF in the south of the Eastern Pontides was assessed in the medium to high risk group.…”

“…In green: negative amplifications. Figure 28 presents a comparison of the 475-year PGA distribution of our Poisson model with the mean 475-year PGA from the updated PSHA model of Turkey [71][72][73]. It would be difficult to provide a full description of the source modelling in the latter; however, we may say that the new Turkish seismic hazard model is composed of two independent source models, an area source model (assigned 50% weight in the final logic tree) and fault source and smoothed seismicity model (again weighted as 50% in the final logic tree).…”

“…Based on the evaluation of regional earthquake ground motion recordings and statistical ground motion prediction equation (GMPE) selection methods, [70] proposed an up-to-date logic tree for the characterisation of the ground motion in Turkey, which was later used in the update of the Turkish national seismic hazard maps [71][72][73]. As the main focus of the present study is an update of the source characterization in the Marmara region, we adopt for all source models (fault and background) the GMPE logic tree proposed by [70] for active shallow crustal regions, which consists of four models and associated weights as presented in Table 5.…”
