Just 50 years have passed since Gurgen Tamrazyan (1968) wrote: “Seismic activity of the Earth undoubtedly is characterized by regularities, which are poorly understood at present”. Due to stagnation of the general theory of physics, today we in fact are in the same position.
Matter irradiated fields are considered to cause several phenomena in geophysics. Despite calculations according to gravity (the Moon attracts us ca. 170 times weaker than Sun does) the Moon causes two times higher tides than the Sun and is thought to trigger more earthquakes, than the Sun (Shimshoni, 1971).
The same proportion appears in (non-gravitational) interaction with the Sun, the Moon and satellites (McDonald, 2005).
Solar tides in Earth’s ocean show an interesting unexplained annual cycle- with maximums at summer and winter solstices and minimums in equinox points (Van Baak). Probably it is an interaction of the Earth’s self-rotating liquid mass-generated field and the Sun’s matter irradiated field with water.
Seismologists have known for a long time, that statistically at times of conjunction of the Moon, the Sun and the Earth (around full Moon and new Moon) as well as when the Moon comes closer to the Earth, probability of earthquakes increases (Milne, 1883; Schuster, 1897; Imamura, 1904; Tamrazyan, 1967; Tamrazyan, 1968, cf.Fogerty, 1969).
P.Biagi et al (2004) observed rhythmical deformations of Earth’s crust within lunar and semilunar month period (detected by content of argon in groundwater). He found also semi-annual, annual and seasonal periods of similar deformations.
Increased number of earthquakes during winter and summer solstices (Mizrahi, 2010) can be partially explained by action of the Sun’s MIF as a function of height of the Suns’ path over equator and asymmetry of Earth’s orbit.
