Analysis of Seismicity Along the Northern Sea Route in the Western Sector of the Russian Arctic

The article analyzes the seismic situation along the Northern Sea Route, located in the western Sector of the Russian Arctic. We compiled a research area seismic catalog from the beginning of the 20th century to 2023. According to the results of the spatial distribution of earthquakes, 6 zones have been identified, characterized by varying degrees of seismic activity. The greatest seismic activity was recorded in the area of the Severnaya Zemlya archipelago and the Taimyr Peninsula, the least in the southeastern part of the Barents Sea. In each selected zone, a comparison of seismicity with available geophysical data (heat flow, tectonic situation, gravio- and magnetic anomalies) is given. The results can serve as a basis for subsequent studies related to the assessment of potential natural and man-made risks of the Northern Sea Route.
