Abstract

The work is devoted to the problem of identifying zones of seismic generstion zones of Fennoscandia, for the solution of which structural-geomorphological interpretation was carried out, seismicity analysis and computer modeling of the latest geodynamics were performed. According to the results of structural-geomorphological interpretation, the territory under consideration was divided into 6 large blocks. Computer modeling showed that each of them is characterized by a certain type of stress state in recent times, and also allowed us to calculate the probability of the formation of new short-distance faults. The reliability of the constructed models is evidenced by the established numerical correlation between this parameter and the density of earthquake epicenters. Based on the data on the density of earthquake epicenters and areas of the possible formation of new faults, a map of seismic generation zones of Fennoscandia was developed.
