“…In our case, the estimates of p in most of the cases are greater than 1 (Figure 4a, Figure 6c). Moreover, according to the field [Sharma et al, 2023; and laboratory [Smirnov et al, 2019] data, a correlation is found between the parameters of the Omori -Utsu law and changes in stresses, indicating the limitations of the model.…”

“…In addition, the parameters p and c of the Omori -Utsu law are correlated. For example, during fracturing along the formed fault, the relaxation parameter p increases with the increase of axial stresses; the delay in the onset of power-law decay (the parameter c in the Omori -Utsu law) decreases with an increase in axial stresses and increases with an increase in comprehensive compression pressure [Smirnov et al, 2019]. In addition, a number of laboratory and field studies revealed a correlation between the Omori -Utsu and Gutenberg -Richter parameters, indicating implementation of various relaxation mechanisms [Sharma et al, 2023;Smirnov et al, 2019.…”

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.

“…The b‐value of the Gutenberg‐Richter distribution becomes much larger than 1 (Figure 8 black curves). One possible hypotheses for explaining this is that the b‐value can be related to the level of stress (e.g., Main et al., 1989; V. B. Smirnov et al., 2019; V. Smirnov & Ponomarev, 2020; Dong et al., 2022).…”

“…Since early studies in 1960s (e.g., Scholz, 1968), impulsive acoustic emission events observed during the rock physics experiments are often considered as analog of natural earthquakes and are used to study the seismogenic processes in controlled laboratory conditions (e.g., Bolton et al., 2023; Lockner et al., 1991; Marty et al., 2023; McLaskey & Kilgore, 2013; V. B. Smirnov et al., 2019; Yoshimitsu et al., 2014). Analyses of large catalogs of “laboratory earthquakes” demonstrated that they obey statistical distributions similar to “natural” earthquakes.…”

We develop a method to estimate relative seismic moments M0 and corner frequencies fc of acoustic emission events recorded in laboratory experiments from amplitude spectra of signal's coda composed of reverberated and scattered waves. This approach has several advantages with respect to estimations from direct waves that are often clipped and also are difficult to separate in experiments performed on small samples. Also, inversion of the coda spectra does not require information about the source locations and mechanisms. We use the developed method to analyze the data of two experiments: (a) on granite from the Voronezh crystal massif and (b) on Berea sandstone. The range of absolute corner frequencies estimated in both experiments is around 70 − −700 kHz. The range of relative seismic moments covers 103.5. The relation between fc and M0 observed on the first stages of both experiments, consisted of increasing isotropic confining pressure, approximately follow scaling and the b‐value of the Gutenberg‐Richter distribution was found close to 1. This can be interpreted as rupturing of preexisting material defects with a nearly constant stress‐drop and has a similarity with observations of “natural” earthquakes. Deviations from this “earthquake‐like” behavior observed after applying axial loading and initiation of sample damaging can be interpreted as changes in stress‐drop. Lower stress‐drops prevail for sandstone and higher for granite sample respectively that can be related to the strength of corresponding material.
