“…The NAFZ stretched (1200 km) from Saros Gulf in the Northern Aegean Sea to the Karliova triple junction in Eastern Anatolia and have a broad arc-shape. It forms a border between Anatolian and Eurasian plates almost parallel to the Black Sea coast maintaining a relatively regular distance of 100 km from the coast (Akin et al 2016;Bayrak et al 2011;Bozkurt 2001). The study area, Yolkonak station is shown in Figure 1.…”

Around the world, earthquake forecasting studies have become very important nowadays due to the increase in number of fatal earthquakes annually. This paper proposes to achieve a possible relationship between soil radon gas concentration and atmospheric Total Electron Content (TEC) during earthquakes taking into account magnetic effects on the North Anatolian Fault Zone (NAFZ) in Turkiye. The ARIMA and Monte Carlo Simulation (MCS) are employed for determining radon gas concentrations by taking into account magnetic effects as an innovative approach. In the study area relatively small and medium-scale earthquakes have taken place during the observation period. As a result of the investigations, the relationships between each of the parameters and earthquakes are determined, and hence, a good relationship is obtained between Rn gas anomaly and micro-seismic activity. In the ionosphere, geomagnetic activity has a primary impact and long duration on TEC distribution, but due to microseismic events it has rather small in uence. The proposed ARIMA and MCS simulations to detect changes in soil Rn gas concentrations have signi cant results for detecting micro-seismic activity anomalies.

“…One-dimensional analysis (i.e., assuming horizontal soil layers, boundaries of infinite lateral extension, and vertically propagating shear waves) has proved adequately to model the propagation of the seismic waves through the soil profile (e.g., [42,43]). en, the equivalent linear method for the one-dimensional site response analysis has been widely used in both research and engineering practices (e.g., [9,17,36,[42][43][44]) due to its simplicity, flexibility, and robustness. Based on this method, many calculation programs are implemented and improved day by day, such as the SHAKE91 [45], ProShake [46], DEEPSOIL [47], and our LSSRLI-1 [48,49] which has the same basic theory, and the validity of LSSRLI-1 was verified and compared with that of SHAKE91 and DEEPSOIL by Ma and Ding [50] erefore, the one-dimensional seismic site response calculation of the nuclear power plant site underlying a hard interlayer in this paper will be carried out by our program LSSRLI-1.…”

“…e damage of earthquake was found to be very selective of site conditions [10][11][12][13][14] which generally refer to local geological conditions, such as the near-surface soil layer, topography, and fracture zones. Existing studies [10,[15][16][17][18] have shown that the impact of site conditions on seismic damage is due to their significant ground motion amplification or deamplification effect. e influence of the nearsurface soil layer on seismic effects has attracted a lot of research due to its widespread impact and the large number of sites involved, and the research studies focused on the formation age [6,7,[19][20][21], genetic type [22][23][24][25], thickness variability [26][27][28], structure [29][30][31][32][33][34], and dynamic characteristics of overlying soil layers [35][36][37][38][39].…”

Based on the engineering geological data of a nuclear power plant site, nine engineering geological profiles were created with hard interlayers of different thicknesses. The equivalent linearization method of seismic motion segment-input used for one-dimensional nonlinear seismic response analysis was applied to study the effect of the interlayer thickness on the peak acceleration and the acceleration response spectra of the site seismic response. The results showed that there was an obvious influence of hard interlayer thickness on site seismic responses. With the increase of hard interlayer thickness, the site nonlinear effect on seismic responses decreased. Under the same thickness of the hard interlayer, the nonlinear effect of the site was strengthened with the higher input peak acceleration. In addition, the short-period acceleration response spectrum was found to be significantly influenced by the hard interlayer and showed that the longer the period, the less influence of the hard interlayer on the acceleration response spectrum coordinates. Moreover, the influenced frequency band was wider with the increase in the thickness of hard interlayer.
