Abstract
This paper presents the capabilities of the Franz Josef Land, Omega, and Severnaya Zemlya island-based seismic stations for seismicity monitoring in the Arctic region. We first analyze how seismicity parameters in the European sector of the Arctic region change over time; we then compare the spectral power density of microseismic noise for positioned seismic stations sites to Peterson models; and finally we analyze MLrepr variations and the accuracy of earthquakes location. To assess registration capabilities, we examined the monitoring results obtained for the Gakkel Ridge, which is characterized by ultra-slow spreading.
