Abstract. The paper presents a description of a software package developed for automated monitoring of the seismic activity of the Khibiny mountain massif. The description of the general structure of the software package is given, the applied methods and algorithms are considered in detail. In particular, the algorithm for locating the source of a seismic event by searching on grids, which are specified in the form of sets of circles and are detailed during the execution of the algorithm, is described in detail. The proposed location methods are combined into several packages – scenarios to optimize the time spent by a geophysicist in routine interactive processing of a large data array. In view of the fact that the described software package was created to process data from seismic networks located directly in the mining area, much attention is paid to increasing the reliability of detecting target signals in a highly noisy environment and the accuracy of determining the moments of body wave arrivals. To solve these problems, the system implements a new approach to the location of close events, based on the idea of a holistic perception of a signal record, which is very close to the concept of human perception of objects. The algorithms and methods for detecting and locating seismic event generation sites implemented in the software package can significantly increase the reliability of the solutions obtained, increase the accuracy and efficiency of the final interactive processing of seismic signal records.
