A total of over 360 records of earthquakes at depths of 0–33 km have been processed; these earthquakes were recorded at the PET station from two regions enclosed in the coordinates 45.0°–50.5° N and 54.0°–56.5° N (for the sake of brevity these regions will be referred to in what follows as the southern and the northern region, respectively). In addition, for comparison purposes we used records of earthquakes made at the KGB station from the area between 52° and 54° N. We used a method based on the ratio of peak amplitudes of Sn and Pn waves. It was found that the overall attenuation in the lithosphere of the northern region is much greater than that for the southern. At the same time we note that the attenuation in both of these areas is below that in northeastern Japan. The relatively lower attenuation occurs in the rupture zones of the great earthquakes occurring in 1952 (<i>M</i><sub>w</sub> = 9.0) and in 1963 (<i>M</i><sub>w</sub> = 8.6), that is, at least 60 years ago in the southern region, while the higher attenuation occurs in the rupture zones of recent events, 1997 (<i>M</i><sub>w</sub> = 7.8), 2006 (<i>M</i><sub>w</sub> = 8.3), and 2018 (<i>M</i><sub>w</sub> = 7.3). These data are consistent with the previous inferences, namely, that typical large earthquakes in subduction zones occur in earth volumes with higher concentrations of fluids in the uppermost mantle. Following large and great earthquakes, deep fluids are rising during a few decades, producing a decrease in the attenuation of the uppermost mantle. We have identified zones of high attenuation where large (<i>M</i><sub>w</sub> ≥ 7.7) earthquakes occurred long ago.

Kinematic characteristics have been obtained for the spatial migration of seismic activity. It is shown that the seismic events recorded by NORSAR, the Norwegian regional network, as occurring within the Russian part of the Barents Sea shelf make linear clusters along strike slip faults. The fault network displaces Mesozoic seismic sequences and emerges at the bottom surface by displacing Quaternary deposits. This clearly indicates a present-day age of the faults along which the linear clusters of low magnitude seismicity aligned. The computation of the total seismic moment in the space-time domain showed the presence of a seismic activity migration along short fault segments in the shelf at rates of 10.5 to 25.7 km/year. A burst of general activity in the shelf area beginning in 2012 could be noted. Comparison of the time-dependent evolution of seismic activity in the shelf to fragments of the Atlantic–Arctic Rift System suggests that the evolution is due to tectonic deformation waves that are initiated along the geodynamically active plate boundary and are propagating to the shelf at a rate of 20‒22 km/year. Another alternative, namely, that the rate of migration can reach 77 km/year, is less likely.
