A method of data interpretation based on the ratio of spectral amplitudes is proposed, which can be applied as one of the possible approaches, not only as an explosion/earthquake discriminant, but also for confident identification of the analyzed explosion belonging to a specific quarry. The possibility of applying the criterion associated with a change in the trend sign lg(P(f)/Lg(f)) with an increase in frequency is considered for identifying seismic events recorded by the unique scientific installation of the IDG RAS by the small-aperture seismological group of the MSG "Mikhnevo" occurring in the central part of the East European Platform. Studies have been conducted on the possibility of reliable interpretation of seismic data with a small magnitude threshold, of the order of ML=1.5, in order to identify errors in the recognition of explosion/earthquake signals. The results of the application of this technique for the analysis of wave forms obtained from both regional earthquakes and quarry explosions for various epicentral distances recorded at the MSG "Mikhnevo" are described.
