    Sed Model: Sun-Spots, Robby's Vortices, Two-Spin Effect Solitonic Decision of Sed Mechanism

    Achievements of space science during last years brought us closely to understanding of physics of solar-earth disturbances ("SED"). However, to construct a SED rigorous mathematical model, the mechanism of seismic excitation in the Sun-earth ("S-E") system is required to be considered. Such a model is required to construct dynamic model of earthquakes.

    Presently, it is found that earthquakes originata for several reasons (They are five -six) . but in all reasons the mechanism in self-excitation of seismic waves "S-E' system takes part in one was or another. Therefore, to crate a theoretical model of earthquakes and to calculate the trigger and release mechanisms , mathematical model for mechanism of seismic excitation in the "S-E" model is required to be develop, and various versions of scenarios occurred have to considered.

    Dynamical model of earthquakes [1-2], proposed by us and constructed on the base of resonance theory for coincidence of seismic waves within different frequency ranges wuth the Earth's eigenoscillations, can be successfully implemented on the base of developing the SED theory taking all causes and mechanisms which generate them into account. Let's consider the main causes of initiating earthquakes, which are currently known.
    1. maxima of solar activity, which are related with coincidence of different cycles.
    2. tidal mechanism-tide-rasing forece4s of the Moon and of the other planets in solar system.
    3. coincidence of "S-E" resonance oscillations related with the Earth revolution round the sun;
    4. origination of D-waves and trigger mechanism for exciting the small interplanetary magnetic fields; origination of origination of regundant pressure zone in atmosphere ( high pressures, cyclones in ionosphere. ). Antheropogenci ( technogenic )man's activity on the planet's scale, is also the cause for origination of earthquakes. In particular case, it is :
    5. anthropogenic ( technogenic ) man's activity ( turns of river's beds, creation of man-mode water reservoirs , intensive exploitation of mineral deposits, building of hydrotechnical.
    6. man-initiated explosion ( nuclear tests, large-scale industrial explosions, starts for rockets ).
    These causes can be grouped into three groups.
    1. Group A- causes (1,2) related with SED;
    2. Group B-causes (5,6) related with anthropogenic man's activity.
    3. Group T- causes (3,4), so called " quiet earthquakes, related with excitation of small magnetic fields (ESMF) in interplanetary medium.
    Each of above-listed groups ahs its trigger mechanism for excitation and initiation of earthquakes, though they have many common things. An if the first A-B groups of causes are to some extent studied, then T-group has been studied very poor, its nature hasn't been studied completely. Therefore, 'T" group of causes-"quiet" earthquakes-are hardly predictable today & they just provide great hazard, since the mechanism for trigger excitation of small interplanetary magnetic fields ( "ESIMF") hasn't been studied. Ignoring even one of causes listed, whole design technique for prgnosis of earthquakes can be reduced to nothing ( zero ). Therefore, it's so important to study each of o cause in details, and to develop respective design technique, and to consider various versions of scenarios and trigger mechanisms causing them.
