This study continues the mathematical justification of a promising concept of the initiation of displacements in fault-block media for providing a local decrease in the elastic energy and reduction of the seismic danger. The system is numerically simulated within the framework of a minimalistic variant of the model formulated previously based on an analysis of the dynamics of one tectonic platform moving on another. The proposed model well describes the known statistics of behavior of the relevant geological media and reveals correlations in the propagation of a dynamically active front. These correlations have been used to select optimum scenarios of the necessary weak local energetic action. This approach significantly increases the efficiency of this type of initiation for the transformation of the block dynamics from the stick-slip to the creep regime, as a result of which the average energy of seismic shocks significantly decreases. This makes the "suppression" of strong earthquakes possible in principle.
