Popis: The paper addresses the methodic questions of arrangement and implementation of local temporal seismologic observations targeting research on karst. We describe an approach for the quantitative assessment of the feasibility for recording the seismic effect of dynamic phenomena accompanying the karst processes. The approach copes with the specific features of excitation, propagation, and recording of seismic waves for a given karsting massif. The adequacy of this approach is supported by the results of experiments on the imitation of collapses in the test object, namely in the Kungur ice cave (Perm region). We describe the experience in application of approaches developed in “big” seismology in the choice of the optimal configuration of the local seismic group (taking into account the properties of stationary microseismic noises) and methods for data processing (identification of the nature of signals) as applied to the conditions of the study of karst processes. Based on the observations performed in Kungur, Perm region, the efficiency of the use of the local seismic group for discriminating signals of an exogenous and endogenous nature is demonstrated.
