The Confirmed Validity of the Explanatory Aspect of the Thermohydrogravidynamic Theory Concerning the Evaluated Maximal Magnitude of the Strongest Earthquake during the Considered Intensification of the Global Natural Processes from December 7, 2019 to April 18, 2020 AD

We present the confirmed validity of the significant explanatory aspect of the thermohydrogravidynamic theory (Simonenko, 2007, 2009, 2012-2020) concerning the evaluated (on April 7, 2021, especially for the presentation on the 11th International Conference on Geology and Geophysics) maximal magnitude 7.725 of the possible most strongest earthquake during the considered (Simonenko, 2020) intensification of the global natural processes of the Earth from December 7, 2019 to April 18, 2020 AD. To obtain the satisfactory explanation of the maximal magnitude M = 7.7 (according to the U.S. Geological Survey) of the strongest earthquake occurred on January 28, 2020 AD (123 km NNW of Lucea, Jamaica) near the calculated (Simonenko, 2020) mean date (February 5, 2020 AD) of the probable most strongest earthquake during the considered (Simonenko, 2020) range from December 7, 2019 to April 18, 2020 AD, we have analyzed the strongest earthquakes of the Earth occurred near the calculated local maximal combined (planetary and solar) integral energy gravitational influences on the internal rigid core of the Earth.


Introduction
The problem of the long-term predictions of the strong earthquakes (Richter, 1958) is the significant problem of the modern geophysics (Sgrigna & Conti, 2012). It was confirmed (Tinivella et al., 2013) in the special issue on "Geophysical Methods for Environmental Studies" of the International Journal of Geophysics that the article (Simonenko, 2013) "proposes a possible cosmic energy gravitational genesis of the strong Chinese 2008 and the strong Japanese 2011 earthquakes, based on the established generalized differential formulation of the first law of thermodynamics" (Tinivella et al., 2013).
Using the evaluated probabilities cor,i Pr (given by (37) in  for i from i = 9 to i = 22), we calculated (on October 6, 2020, especially for the presentation on the 10 th International Conference on Geology and Geophysics) the mean (defined statistically) theoretical date t(2019, 2020) 2020.0995139 February 5, 2020 AD = = of the probable most strongest earthquake during the considered (Simonenko, 2019b range from December 7, 2019 to April 18, 2020. We obtained ) the reasonably small difference of 8 days between the calculated theoretical date (February 5, 2020 AD) and the real date (January 28, 2020 AD) of the most strongest (from December 7, 2019 to April 18, 2020) earthquake (characterized by the maximal magnitude M = 7.7) of the Earth occurred 123 km NNW of Lucea, Jamaica (according to the U.S. Geological Survey) during the considered (Simonenko, 2019b range from December 7, 2019 to April 18, 2020 AD. The main aim of this article is to present (in accordance with the author's presentation on the 11 th International Conference on Geology and Geophysics) the reasonable explanation (in the frame of the thermohydrogravidynamic theory (Simonenko, 2007(Simonenko, , 2009(Simonenko, , 2012) of the maximal magnitude M = 7.7 of the most strongest (from December 7, 2019 to April 18, 2020 AD) earthquake of the Earth occurred on January 28, 2020 AD (according to the U.S. Geological Survey) during the considered (Simonenko, 2019b range from December 7, 2019 to April 18, 2020 AD. In Section 2 we present the fundamentals of the thermohydrogravidynamic technology for evaluation of the maximal magnitude of the strongest earthquake of the Earth during the considered (Simonenko, 2019b intensification of the global natural processes of the Earth from December 7, 2019 to April 18, 2020 AD. In Section 2.1 we present the established (Simonenko, 2006(Simonenko, , 2007a(Simonenko, , 2007b generalized differential formulation (1) of the first law of thermodynamics. In Section 2.2 we present the established (Simonenko, 2012(Simonenko, , 2014 global prediction thermohydrogravidynamic principles (6) and (7) determining the maximal temporal intensifications of the global and regional natural (seismo-tectonic, volcanic, climatic and magnetic) processes of the Earth.
In Section 3 we present the explanation of the maximal magnitude M = 7.7 (according to the U.S. Geological Survey) of the strongest earthquake of the Earth occurred on January 28, 2020 AD during the considered (Simonenko, 2019b range from December 7, 2019 to April 18, 2020 AD. In Section 4 we present the main results and conclusions. The thermohydrogravidynamic technology of evaluation of the maximal magnitude of the strongest earthquake of the Earth (during the considered (Simonenko, 2019b, 2020) intensification of the global natural processes from December 7, 2019 to April 18, 2020 AD) is based on the established (Simonenko, 2006(Simonenko, , 2007a(Simonenko, , 2007b generalized differential formulation of the first law of thermodynamics (for an individual finite continuum region τ subjected to the non-stationary Newtonian gravitation and to non-potential terrestrial stress forces characterized by the symmetric stress tensor Т ): τ τ τ np, τ dU dK dπ δQ δA dG,
Introducing the energy flux g J of the gravitational energy (per unit time and per unit area) across the differential surface element dΩ n characterized by the external normal unit vector n , the relation for dG can be rewritten as follows (Simonenko, 2012(Simonenko, , 2014 where the flux g J of the gravitational energy is determined by the relation (Simonenko, 2012(Simonenko, , 2014:

The Global Prediction Thermohydrogravidynamic Principles Determining the Maximal Temporal Intensifications of the Global Natural Processes of the Earth
The rigorous global prediction thermohydrogravidynamic principles are formulated (for the internal rigid core c,r τ of the Earth) based on the term (2) of the generalized differential formulation (1) of the first law of thermodynamics (Simonenko, 2007a(Simonenko, , 2007b as follows (Simonenko, 2012(Simonenko, , 2014(Simonenko, , 2018(Simonenko, , 2019a: where c,r ρ is the mass density of the internal rigid core c,r τ , comb comb c,r ψ ψ (τ ,t) ≡ is the combined cosmic (planetary and solar) gravitational potential in the internal rigid core c,r τ of the Earth, time derivative of the combined cosmic gravitational potential comb c,r ψ (τ ,t) . The partial time derivative (of the combined cosmic gravitational potential comb c,r ψ (τ ,t) ) is approximated as follows (Simonenko, 2007(Simonenko, , 2009(Simonenko, , 2012(Simonenko, , 2013 of the gravitational potential 3i 3 ψ (C ,t) created (at the mass center 3 C of the Earth) by the significant planet i τ (i = 1 corresponds to Mercury, i = 2 corresponds to Venus, i = 4 corresponds to Mars and i = 5 corresponds to Jupiter); (Simonenko, 2012(Simonenko, , 2019a partial time derivative of the gravitational potential S 3j 3 ψ (C ,t) created (at the mass center 3 C of the Earth) by the Sun due to the gravitational interaction of the Sun with the outer large planet j τ (j = 5 corresponds to Jupiter, j = 6 corresponds to Saturn, j = 7 corresponds to Uranus) and j = 8 corresponds to Neptune).
