Abstract

The paper discusses formation features of seismogenic zones in the region. The study revealed interrelation between areas of their localization and areas of their occurrence in the geological basement of weakened zones developed in the early Precambrian. The performed numerical modeling made it possible to construct models of the stress-strain state of the Earth's crust in the region considering its evolution and to determine the structures that hosted ancient mobile-permeable regions. These areas are overlapped by the known seismogenic zones in the major part of the territory. A significant number of seismic events, both ancient and modern, are also concentrated there. In total, the selected weakened structures produce a framework that permeates the basement of the Kola region capturing the water areas of the Barents and White Seas. The greatest part of mineral deposits of the region is located within these areas. The economic activity is also concentrated there, which affects the ecological situation in the region. In case of some seismic activity, these zones become potentially dangerous during the stress relief between geoblocks. In addition, the powerful mining and industrial complex of the Murmansk region generates technogenic seismic events by disturbing the natural equilibrium in mountain massifs. Thus, when natural and technogenic processes accompanied by tectonic rockburst are overlapped, seismic events with an increased level of magnitude are generated more often. As a result, environmental risks increase and civil and industrial facilities become more vulnerable.
