Registration Capabilities of Russian Island-Based Seismic Stations: Case Study of the Gakkel Ridge Monitoring

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 spectra...

Description
Summary: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 M L repr 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.
