“…This allows to obtain the estimate of the parameter b a for all the data regardless of the level of watering of the rock environment. This estimate is necessary during the assessment of post-seismic danger, for example, during the calculation of the parameters of the dynamic Bath's law [Baranov et al, 2022;Motorin and Baranov, 2022].…”

The article is devoted to the study of the influence of watering of the rock environment on post-seismic activity in the deposits of the Khibiny mountains. Initial data are the results of long-term monitoring of seismicity and observations of water inflows. At a qualitative level, the influence of watering of the environment on the b-value of the Gutenberg – Richter distribution of magnitudes of triggered events, as well as on the parameters of the Omori – Utsu law, which describes the post-seismic activity decay rate over time, was studied.

“…Post-seismic activity is described by three laws of statistical seismology: Gutenberg -Richter [Gutenberg and Richter, 1944], Omori -Utsu [Utsu et al, 1995], and earthquake productivity [Baranov et al, 2022;Shebalin et al, 2020]. The Gutenberg -Richter law specifies the distribution of magnitudes.…”

“…Some authors have tried to give a generalized form of this law in the form of a differential equation and introduced the idea of a "cool down" process after the mainshock [14,15]. In the end, the goal has been to characterize the behavior of aftershocks so the general activity can be predicted after a big event and therefore, asses the risk in a given zone [16]. In addition, there seems to be a relationship between the parameter b of Gutenberg-Richter and the parameter p of Omori which governs the speed of the aftershock's decay [17][18][19][20].…”

The Olami, Feder and Christensen (OFC) spring-block model has proven to be a powerful tool for analyzing and comparing synthetic and real earthquakes. This work proposes the possible reproduction of Utsu’s law for earthquakes in the OFC model. Based on our previous works, several simulations characterizing real seismic regions were performed. We located the maximum earthquake in these regions and applied Utsu’s formulae to identify a possible aftershock area and made comparisons between synthetic and real earthquakes. The research compares several equations to calculate the aftershock area and proposes a new one with the available data. Subsequently, the team performed new simulations and chose a mainshock to analyze the behavior of the surrounding events, so as to identify whether they could be catalogued as aftershocks and relate them to the aftershock area previously determined using the formula proposed. Additionally, the spatial location of those events was considered in order to classify them as aftershocks. Finally, we plot the epicenters of the mainshock, and the possible aftershocks comprised in the calculated area resembling the original work of Utsu. Having analyzed the results, it is likely to say that Utsu’s law is reproducible using a spring-block model with a self-organized criticality (SOC) model.
