Zusammenfassung
The data from seismic stations of the Arkhangelsk network and the networks in the neighboring territories are analyzed for refining the focal parameters of the tectonic earthquakes recorded in the north of the Russian plate on October 22, 2005 (M = 2.9) and March 28, 2013 (M = 3.4). The epicenters of the earthquakes are confined to the large NW–SE striking faults which border the Arkhangelsk bulge starting from the Kara–Pinega rift in the northeast and Onega–Kandalaksha paleorift in the southwest. The calculated focal mechanism of the earthquake of March 28, 2013 agrees with the distribution of neotectonic stresses characteristic of the north of the Russian plate, and specifically, with the submeridional compression and sublatitudinal extension.
