Current state and prospects of the development of an Arctic seismic monitoring system

Resumo

The expansion of industrial and defense activities in the Arctic as part of the execution of a state program on the development of its territory requires seismic safety assurance of constructed and existing critical facilities. The data presented in this paper show that the current understanding of the seismicity of the Arctic and particularly of its shelf given in building regulations is quite simplistic and does not reflect the complexity of the situation and the intensity of expected seismic effects. To a large extent, safety problems can be solved by the seismic monitoring of the area. For this purpose, it is necessary to expand existing networks of seismic stations, to equip them with tools for monitoring groups, and to increase the number of island seismic stations. The primary task is to refine the seismic zoning of Arctic territories based on the new data.
