“…The stimulation of energy low focuses was illustrated by Guglielmi et al [39]; by using the widespread indices, the Wolf numbers W, to characterize solar activity the authors have found the certain relationship between earthquakes and solar activity. The global daily magnitudes M g , calculated over the 20-year period from 1980 to 1999, were correlated with daily W numbers; the pairs M g −W are shown in Figure 2.…”

The ultimate and noble goal of seismology as a science is to find reliable means to predict the place, time and magnitude of expected earthquake. There are significant achievements on the way to this goal: there is a fairly clear understanding chemical physics and mechanics of the earthquake, there are reliable indicators and precursors of the approaching seismic events. However, this understanding remains to be purely intellectual achievement; it looks like highly desirable but hardly attainable purpose. Earthquake prediction is unattainable like absolute zero temperature: you may approach it, but never reach. As an alternation there is reliable evidence that microwave induced release of energy, accumulated in the earthquake focus, may be implemented by hand-made means (such as magneto-hydrodynamic generators). Magnetic control of the earthquake focus by microwave exposure is a unique means to decrease magnitude of the earthquake and transform catastrophic event in the less dangerous one. However, positive experience of reducing the magnitude of earthquake is rather limited and hardly may be implemented in practice; evidently, earthquake control is unfeasible project.

“…The idea that space weather-as measured by sunspots, cosmic rays, solar wind, interplanetary magnetic fields, geomagnetic activity, and precipitation of charged particles from the radiation belt-may play a role in triggering earthquakes has a long history but has not received physical justification for the time being. It was noted in [1] that the problem's difficulty is that the unknown is a physical mechanism of action involving relatively weak fields of cosmic origin on tectonic processes. The authors of [2] suggested that geomagnetic variations affect rocks, e.g., by inducing eddy currents in the Earth's crust via an alternating magnetic field, leading to rocks' additional heating.…”

“…The GEC links the electric fields and currents flowing in different parts of the atmosphere [12,13]. There are three main generators of fields and currents in the global electric circuit [13]: (1) the troposphere generator (continuous thunderstorm activity of the Earth, with about 46 lightning strikes per second); (2) the ionospheric wind dynamo; and (3) the solar wind/magnetosphere dynamo. The troposphere generator may provide a 200 kV to 600 kV potential difference between the ground and the ionosphere.…”

In solar–terrestrial physics, there is an open question: does a geomagnetic storm affect earthquakes? We expand research in this direction, analyzing the seismic situation after geomagnetic storms (GMs) accompanied by the precipitation of relativistic electrons from the outer radiation belt to form an additional radiation belt (RB) around lower geomagnetic lines. We consider four widely discussed cases in the literature for long-lived (weeks, months) RBs due to GMs and revealed that the 1/GMs 24 March 1991 with a new RB at L~2.6 was followed by an M7.0 earthquake in Alaska, 30 May 1991, near footprint L = 2.69; the 2/GMs 29 October 2003 (Ap = 204) with new RB first in the slot region at L = 2–2.5 cases followed by an M7.8 earthquake on 17 November 2003 at the Aleutian Islands near footprint L = 2.1, and after forming an RB at L~1.5 which lasted for ~26 months, two mega quakes, M9.1 in 2004 and M8.6 in 2005, occurred at the globe; the 3/GMs 3 September 2012 with a new RB at L= 3.0–3.5 was followed by an M7.8 earthquake in Canada near footprint L = 3.2; and the 4/GMs 21 June 2015 with a new RB at L = 1.5–1.8 was followed by an M6.3 earthquake on 7 September 2015 in New Zealand, near footprint L = 1.58. The obtained results suggest that (1) major earthquakes occur near the footprints of geomagnetic lines filled with relativistic electrons precipitating from the outer radiation belt due to geomagnetic storms, and (2) the time delay between geomagnetic storm onset and earthquake occurrence may vary from several weeks to several months. The results may expand the framework for developing mathematical magnetosphere–ionosphere coupling models.

The article addresses the problem of the connection of earthquakes with geomagnetic phenomena. We have carried out an experimental study using a method based, firstly, on the separation of periods of geomagnetic activity into extremely quiet and disturbed, and, secondly, on the description of seismic activity with an index called the global daily magnitude (GDM). By analyzing the NEIC earthquake catalog of the US Geological Survey over a 20-year period from 1980 to 1999, we have shown that the planetary activity of earthquakes under extremely quiet geomagnetic conditions is noticeably higher than under disturbed conditions. The detected tendency for seismic activity to increase in extremely quiet periods of geomagnetic activity has indirectly been confirmed by the analysis of 35 earthquakes with magnitude 8 and higher, which occurred on Earth from 1980 to 2019. We have found that in extremely quiet geomagnetic conditions, the probability of the occurrence of strong earthquakes is noticeably higher. The result qualitatively confirms the assumption of a change in the regime of seismic activity due to the influence of alternating magnetic fields on the ductility of rocks.
