# Comparative Analysis of Target Displacements in RC Buildings for 2023 Turkiye Earthquakes
## 2 Tectonic Structure of Turkiye and 2023 Kahramanmaras Earthquakes
The spectral accelerations recorded during the Pazarck and Elbistan earthquakes at different ground motion stations in the E-W and N-S directions are shown in Figures 3 and 4 respectively. Earthquake Zones map, in use since 1996, was replaced by the Turkiye Earthquake Hazard Map, which was updated in 2019. The earthquake regulation, which has been in use since 2007, was replaced by the Turkish Building Earthquake Regulation in 2019. In this study, seismic parameters for eleven different provinces where the 6 February 2023 earthquakes were most strongly felt, were compared using the last two earthquake hazard maps. In the previous map, seismic parameters were obtained on a regional basis. With the current map, seismic parameters can be obtained separately for different exceedance probabilities for each geographical location and soil class, with the help of the Turkish Earthquake Hazard Map Interactive Web Earthquake Application (TEHMIWA). This application was developed within the scope of the Seismic Hazard Map Update project, which is required in the National Earthquake Strategy and Action Plan for the basic research to be done to reduce the earthquake hazard in the country. In the project, PGA, PGV, and other seismic parameters within the land borders of Turkiye were obtained for different annual exceedance probabilities using the probabilistic seismic hazard methods. The seismic source, earthquake, and ground motion databases formed in Turkiye in recent years were evaluated in the best way in the project, and the country's earthquake hazard map was updated. In the project, seismic sources within the land borders of Turkiye were determined, instrumental and historical earthquake catalogs were compiled, and then seismic parameters were obtained for different exceedance probabilities and ground classes for each geographical location using probabilistic seismic hazard analyses using

Figure 3: Spectral accelerations measured during Pazarck (M\({}_{\rm w}\) = 7.7) earthquake. earthquake recurrence models and ground motion estimation equations. With the help of this application created as a result of the project, seismic parameters can be obtained for any location. In this study, current seismic parameters were obtained with the help of this application [79]. This work considers four different earthquake ground motion levels, including 2%, 10%, 50%, and 68%, which are included in the current earthquake regulation and have a probability of being exceeded in 50 years. The characteristics of these ground motion levels are shown in Table 4.  
To make comparisons in this study, an earthquake with a 10% probability of exceedance, the standard earthquake ground motion level in 50 years, which is included in both regulations, was taken into consideration. ZC soil class, which represents moderate soil class, was taken into account. PGAs and PGVs attained for various exceedance of probabilities at random locations from the provincial centers of the eleven provinces most affected by both earthquakes are illustrated in Table 5.  
The highest PGA value with a 2% probability of exceeding was obtained as 0.890 g for Hatay. The lowest PGA value for this probability of exceedance was 0.221 g for Sanlurfa. For the eleven provinces considered, the PGA range for a 10% probability of exceedance ranges from 0.110 to 0.446 g. For the same earthquake ground motion level, PGV values ranged from 7.922 to 27.623 cm/s. Table 6 presents a comparison of the PGA values anticipated in the previous seismic zones map with those derived from the current earthquake
