Аnnotation: The article summarizes the materials of observations of the small-aperture seismic group (SSG) “Mikhnevo” for seismic events on the territory of the East European Platform based on the analysis of a large number of experimental data, a method for recognizing earthquakes and short-lived group explosions is proposed, based on the nature of the slope of the curve of the distribution of the ratio of the amplitude spectra of P and Lg waves lg( A
