This paper provides information about the main parameters of spatial broadband seismic network in the Kola region (the northeastern part of the Fennoscandian Shield). Since 2021 the seismic network has been expanded by five seismic stations and currently consists of nine stations located on the territory of the Russian Federation. Configuration of the network allows to broaden the scope of research of the Kola region lithospheric structure significantly. The prospects of integrating the newly installed stations into the automated regional seismic monitoring network are considered. The analysis of seismic noise in the places of installation of new seismic stations was carried out. It was shown that the data provided by the new broadband stations increases the accuracy of seismic events location in the research area.

 Arctic Kola region Fennoscandia seismic network location technogenic seismicity earthquakes Arctic Kola region Fennoscandia seismic network location technogenic seismicity earthquakes The research on newly obtained data integration to the GS RAS system and analysis of the seismic activity was supported by the Ministry of Science and Higher Education of the Russian Federation (GS RAS #075-01271-23 and IDG RAS #122040400015-5). New seismic stations installation and data processing was done in accordance with Russian Science Foundation grant #21-17-00161. The data used in the paper was obtained with large-scale research facilities “Seismic infrasound array for monitoring Arctic cryolitozone and continuous seismic monitoring of the Russian Federation, neighbouring territories and the world” (https://ckp-rf.ru/usu/507436/, http://www.gsras.ru/unu/).
