“…This high seismicity is triggered by four different neotectonics districts (Fig. 2) that were discussed in (Yön et al 2020) across Turkey. These include the (1) North Anatolian district, (2) Eastern Anatolian contractional district, (3) Central Anatolian planar district, and (4) Western Anatolian extensional district.…”

“…Currently, Turkey, which is in the East Mediterranean, is one of the most active seismic zones in the world. This high seismicity results in numerous earthquakes (Calayır et al 2012 ; Sayın et al 2013 ; Sayın et al 2014 ; Yön et al 2019 ; Yön et al 2020 ; Doğangün et al 2021 ; Günaydın et al 2021 ; Demir et al, 2020 ; Sayın et al 2021 ; Doğan et al 2021 ; Yön 2021 ) even in the previous year, 2020. This seismicity is caused by 326 separate faults, fault zones or combined systems.…”

An earthquake with a magnitude ranging from Mw = 6.9 (KOERI) to Mw = 7.0 (USGS) struck Samos Island in the Aegean Sea on October 30, 2020, with an epicentre 70 kms from the İzmir city centre in Turkey. The earthquake took place at 14:51 local time (11:51 UTC). The peak ground acceleration (PGA) of this earthquake was recorded to be 0.179 g at the epicentre of the earthquake. This earthquake occurred at a depth of 17.26 km (AFAD (2020) İzmir Earthquake Report, (In Turkish)) and lasted 16 s. The main shock from the earthquake triggered a tsunami that hit the building stocks built near the coast. During the gradual deregulation of COVID-19 pandemic regulations, various events caused considerable damage to the building stock, particularly in the Izmir Seferihisar and Bayraklı regions and resulted in a massive disruption of daily habits. The main shock caused 117 deaths in both Turkey and Greece, and 1632 people were also injured in Turkey. Moreover, several injuries occurred in Greece. A total of 103 buildings collapsed, 700 were severely damaged, 814 buildings were moderately damaged, and 7889 were slightly damaged. The basic aim of this paper is to briefly present the past and present seismotectonic characteristics of the region, present building stock, and former structural conditions before the earthquake, assess structural performance and classify distinguished earthquake-induced failures and damage due to the basin effect.

“…The EAFZ consists of six main fault segments. These fault segments are Karlıova-Bingöl, Palu-Hazar Lake, Hazar Lake-Sincik, Çelikhan-Erkenek, Gölbaşı-Türkoğlu, and Türkoğlu-Antakya segments (Yön et al, 2020), caused shallow seismicity and destructive earthquakes at different times (Bayrak et al, 2015;Gülerce et al, 2017;Bayrak et al, 2020). Figure 1 shows the broadband seismic station distribution.…”

The East Anatolian Fault Zone (EAFZ) is an active plate boundary where an intense earthquake activity has occurred from past to present. This activity is highly related to the geodynamic structure of the region. Because of the northward motion of Arabian plate and southward motion of the Eurasian plate, the Anatolian plate has attempted to escape westward with anticlockwise rotation. This tectonic movement cause the development of important tectonic structures. In relation to these active plate motions, the S-wave velocity structure of the EAFZ intersecting the North Anatolian Fault Zone (NAFZ) in the northeast and the Dead Sea Fault Zone (DSFZ) in the southwest is very important in interpretation the tectonic structure of the region. In this study, it was applied on the joint inversion technique of P-wave receiver functions and Rayleigh wave group velocities by using the data collected from eight broadband stations along the EAFZ. The P-receiver functions were obtained by using approximately eighty teleseismic events seperately for each station, recorded by the three-component broadband seismometers. On the other hand, for the Rayleigh wave group velocity dispersion curves, twenty-one local earthquakes which have focal depth less than 50 km and bigger than moment magnitude Mw=5.0 were used. The results obtained from these two techniques for each station was jointly inverted to determine the 1-D S-wave velocity structure of crust and uppermost mantle. S-wave velocity models along the EAFZ indicate the presence of the low-velocity layers in the upper crust, within the approximately depths of 4-12 km. However, the Conrad discontinuity along the seismic stations was around a depth of ~22 km. Furthermore, the crust-mantle boundary along the EAFZ is about ~44 km depth. Consequently, this study yields the crustal and uppermost mantle S-wave velocity structure compatible with the tectonics of the studied region.

“…The countries, under high seismic risk and where the structural stock needs to be assessed fast and in a correct manner before or after an earthquake, seek to utilize a quick procedure during a numerical analysis [1]. Because structural systems are moderately or severely damaged following an earthquake, as experienced in recent decades [2][3][4][5][6][7][8]. Drift limits and deriving fragility curves are the prominent methods in recent decades to assess a structural system.…”

The basic purpose of this paper is to investigate and propose a novel inter-story drift limits for the current Turkish Seismic Code to get easy structural assessment by using software. For this aim, numerical analysis was performed by modeling two types of RC frame structures. One of them is 5 stories, the other of them is 7 stories. Two different concrete classes, C20 and C25, were considered and three tension reinforcement ratios were considered for analysis. Tension reinforcement ratios were determined by half of the compressive reinforcement, equal to compressive reinforcement and double the compressive reinforcement ratio. Incremental dynamic analyses (IDA) were performed on these buildings. In this study to execute IDA, eleven seismic acceleration benchmark records were multiplied with various scaling factors from 0.2 to 1.0. Maximum base shear and corresponding roof displacement responses obtained from IDA curves were generated according to these responses. IDA curves were compared with each other by deriving fragility graphs. According to results, proposed limits for the current Turkish seismic code (TBEC-2018) provide, 0.6%, 2.4% and 3.3% respectively for MN, GV and GC, rather safe limits compared to drift limits presented in the foredate seismic code (TSC-2007).
