## 1 Introduction
This idea was supported by [13], who studied the relationship between solar activity and the big earthquakes (Ms \(\geq\) 8) that occurred in China and Western Mongolia. They discovered that, in the years of the solar maxima, only those earthquakes occurred in which epicenters were in and near the tectonic faults with west-east strikes. However, those big earthquakes, in which epicenters were located not in such faults, did not occur in the solar maxima. The statistical findings in [13] were rather in agreement with the predictions of the mathematical model [6], which predicts that the tectonic fault's electrical conductivity and geographic orientation play an essential role in the electromagnetic triggering of earthquakes. The stronger telluric currents will be generated when the telluric current density vector is directed parallel to the direction of the tectonic fault. According to a mathematical model [6], at the Northern Hemisphere's middle and low latitudes, the telluric currents' density vectors are oriented predominantly in the west-east direction, which coincides with the orientation of the faults in or near which the epicenters of significant earthquakes in China occurred in solar maxima [13]. The triggering of seismic activity by strong solar flares was discussed in more detail in [14], and the problems related to understanding the physical reasons for the Sun's influence on the Earth's seismicity were discussed in more detail in [15]. The most evident manifestations of solar wind activity on the Earth are geomagnetic storms. There have been many papers in which a possible response of seismic activity to geomagnetic storms was investigated, e.g., [16] (and references herein). Therefore, it was found in [17] that 17 strong earthquakes (M \(\geq\) 6.5) for 1994-2017 occurred within two days after geomagnetic storms when the values of the geomagnetic Kp-indices were above seven and that all these events occurred in the Eastern longitudinal Hemisphere but were absent in the Western one. An analysis of the seismic activity in the Northern Tien-Shan from 1975 to 1996, which was carried out in [18], has revealed that, there, the seismic activity increases, on average, 2-6 days after the onset of a magnetic storm, but this takes place only in those regions, where the rocks have a low electrical resistivity. The authors of [19] investigated data from 4666 strong earthquakes (Mw \(\geq\) 6) in the PacificRim region (120\({}^{\circ}\)-160\({}^{\circ}\)E, 70\({}^{\circ}\)-130\({}^{\circ}\)W) during 1932-2016. They concluded that the forces accompanying the magnetic storm might be responsible for earthquakes triggering with a time delay of \(\sim\)12-14 days. In [20], the correlation between geomagnetic storms and strong (Mw \(\geq\) 7.0) earthquakes that occurred around the globe in 1957-2020 was investigated; statistically significant evidence was found that the probability of geomagnetic storms increased around 26-27 days before earthquakes. The authors of [21] analyzed Mw5.5\({}^{+}\) shallow earthquakes that occurred around the globe from November 2013 to November 2021 in connection with the magnetic field data measured in this period by the three Swarm identical satellites constellation. For major earthquakes (Mw7.5\({}^{+}\)), it was found that the time delay between geomagnetic storm onset and earthquake occurrence may be up to several years. It is assumed, at present, that, during the 11-year solar cycle, two maxima in geomagnetic storm numbers appear--one in the sunspot maximum, when coronal mass ejection (CME) is mainly responsible for the geomagnetic activity, and another one in the descending phase of the 11-year solar cycle, when the high-speed solar wind (HSSW) from the polar coronal holes is mainly responsible for geomagnetic activity [22]. The authors of [23] studied the day-to-day variations in the number of earthquakes relative to the days when the Earth was exposed to the CMEs and when the Earth was exposed to the HSSW in 1973-2000.
