Conclusions
-
1.
On the basis of the consistent physical hypothesis of the nature of stresses in the preparation of a seismic event, the author proposes a mathematical model of the radiator.
-
2.
The algorithms of displacements in longitudinal and transverse waves and the moduli of their amplitude spectra have been calculated.
-
3.
The equations D0=W0Δγ and νo.5 =f(LW 2o ) obtained have made it possible to propose a new method for estimating the focus characteristics with minimal number of free parameters.
