Opis (eng)

In the present paper, we examine the conditions for synchronization of a delayed stochastic model of earthquake nucleation, where each block is under the impact of its previous state and the neighboring blocks and under the stochastic perturbation. As a result of our work, we obtain a sufficient condition for the exponential mean square stability of the synchronization. Results obtained indicate that the bi-directionally symmetric coupling induces the synchronization much less efficiently than the uni-directionally symmetric one. From the seismological viewpoint, it seems that different parts (patches, segments) of the same fault or neighboring faults could exhibit synchronized activity under certain conditions. This could further induce the occurrence of much stronger earthquakes or could extend the duration of earthquakes, which could further have more severe consequences at the ground surface (including the effects on structures and people) compared to the case of effects of unsynchronized motion of different segments AQ1 of the same fault or group of neighboring faults.
