Summary A method was developed for classifying the intensity of seismic events observed in the Karviná part of the Ostrava—Karviná mining district. The method is based on determining the magnitude of events, using the homogenized maximum amplitudes of the S-wave group. The amplitude observations were homogenized by means of station corrections estimated by successive approximation simultaneously with the derivation of the optimum calibrating function. The magnitude classification developed enables an objective and relatively simple estimation of the intensity of seismic events in mines with an accuracy corresponding to the quality of observations. The correlation between the so-called accepted energy, currently used for classifying rock bursts in the Ostrava—Karviná mining district, and the corresponding magnitudes was established.
