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

    1. SED trigger mechanism, causes of group "A"
    Consider, firstly , SED trigger mechanism ( group A). so, there is correlational link is group A6 which is found between growth and evolution of solar-spots ("SS"0 on the sun's surface, between its cycles and activity, and cause for origination of earthquakes and other natural disasters and catastrophes. Just as a result of rotating the spots, seismic waves are focused and so-called Rossby's vartices are originating . SS are the resonators and exciters of powerful seismic waves [3-10] .

    As a result of coincidence of "SS" rotation axes with the Earth's rotation axis, i.e. their parallelism ( orgination of Rossby's vortices, solutions ), seismic waves are transferred and amplified through space medium ( space plasma ) form the sun to the earth due to origination of so-called " Spin-effect " .

    This effect consist in tow rotating system-" spins"-which act as likely charged particles scattering in different directions when approached. Just in this manner the Earth's seismic excitation is enhanced due to increasing he solar activity and rotational speed of sun-spots ( vortices of plasmoides ). For mathematical describing these mechanisms of seismic waves excitation, the model for solution [3-10] is the mot acceptable.

    Condition for transition of resonance situation ("RS") to implementation of catastrophe of particular type ( "RK"), according to the cause of group A, is operation of release mechanism. Just within this time interval for RS-RK, forerunners of catastrophes, which outstrip and predetermine their occurrence, take place.

    These conditions are satisfied for simultaneous coincidence of four independent factors A, B,C,D,/1-2/. These factors are the following.
    1. flares at the sun, curling the magnetic force lines in sun-spots, orgination of shock waves;
    2. focusing the seismic waves in sun-spots within narrow ranges -1-1Hz.
    3. coincidence of spots' rotational axes with Earth's rotational axis, their paraelism ( occurrence of spin-effect hazard);
    4. break-out of caused seismic ray through coronal holes and their interaction with sites of orinfor earthquakes.
    If assume total probability of event as a unit, the share of in depending events is 1/4 , or 0,25, then the total probability of simultaneous coincidence and action of all four factors P is the product of each of them, i.e.

    P=AXBXCXD = (0,25)4    (1)

    According to condition 91), trigger mechanism of excitation ( "TME") transits to resonance situation -"RS"- for tending of TME energy to some ( critical ) limit E cr, i.e.

    TMB -------RS     for TMB---------E cr     (2)

    Transition of resonance situation RS to implementation of particular catastrophe-"RK"- is due to origination of bifurcation ( peculiarities ) in function of catastrophes. According to catastrophes ' theory /8/ , this function consistsin the sum of two function:

    Cat (1,k)= C G (1) + pert (1,k)     (3)

    Where
    Cat 91,k) is catastrophes ' function;

    CG (1) is function of catastrophe's growth;

    Pert 91,k0 is function of catastrophe's disturbance . Thus, taking the conditions (1,2,3) into account, TMB tends to "RS" for "RS" tending to Ecr, and 'RS" tends to "RK" for equal to Ecr, i.e. is expressed mathematically as following;

    TMB--------RS-------RK     for TMB = Ecr     ( 4)

    Beside ' classical " scenarion developed by us for dynamic model of earthquakes, taking SED/1-2/ into account, there are at least, two more trigger mechanisms from "B" and "T" groups of causes.

    II Trigger mechanism of causes from group "B" .
    This group is related with anthropogenic man's activity and various types ofg mechanisms generating extreme stresses inside the Eath's crust, which produce earthquakes. Trigger mechanism of such catastrophes is related with ' accumulation " of stresses inside the earth's crust and the with unexpected release of this energy in stressed areas of the earth's crust. Accumulating process of solitary wave ( soliton ) promoting discharge of accumulated energy and its sudden dissipation which is expressed in orgination of catastrophes. In water environment ( in sea, ocean) it ( solitary wave produces tsunmi ( seaquake ). Trigger mechanism of this phenomenon is complex enough and studied insufficiently in details. But Inspite of this, general method of transition according to (4) - TMB ----RS-----RK scheme, proposed by us, can be quietly used in given case, under condition of more detailed study of mechanism for trigger exciting the stresses in the earth's crust and origination of forerunners related with anthropogenic man's activity.
