Abstract:

There is presented a brief survey of proposed mechanisms of geomagnetic effects of nuclear explosions. On the basis of similarity of effects between nuclear explosions and explosion of the Tungus meteorite in 1908 there is expressed a hypothesis on the similarity of mechanisms even for qualitatively different explosions. There is proposed the following mechanism of geomagnetic effect of nuclear explosions. Immediately after explosion over an area with a radius of 3,000 to 4,000 km., there develops a heightened ionization which creates possibilities favorable for the propagation of hydromagnetic impulse. First phase of perturbation is caused by this impulse. Second or main phase is caused by the action of the shock wave. Lowering of the field and its subsequent-restoration are associated with displacement of currents with respect to the observation stations and their gradual damping. Author
