The crushing victory of the theoretical approach over the experimental approach lasted only until the theory was used to make experimentally verifiable predictions of the tectonic events. When attempts were made to verify such correlations to predict EQ researchers faced two principal questions:
1) How do such electric (charge) global disturbances, coming from the Sun and covering whole globe, concentrate in such very small volumes of earthquakes foci?
2) And how does the mechanical energy of huge cyclonic disturbance concentrate comparatively small volume of the earthquake focus?
Another attempt occurred when researchers were trying to predict where, when and what magnitude would be the next earthquake on the basis of analysis of what has already occurred in the Earth’s depth. The fact that the first seismometer was installed almost 120 years ago it is arguable that it is impossible to predict the place, the time and the magnitude of seismic events on the basis of seismographic (seismometric) data.
