In this paper, a high-tech expert system EEDB for solving a wide range of seismological research tasks is proposed. The logical and functional structure as well as results of the algorithms usage for the analysis of seismic processes are considered. The algorithms allow us to calculate and to visualize maps and diagrams of seismic regime parameters such as parameters of a graph of repeatability, seismic activity quiescence, clusterization of earthquakes, concentration criterion. The analysis software provides a cartographic representation of a seismic characteristics change in space. Examples of the EEDB system application with the view of learning concrete seismic regime anomalies are given.
