Abstract
The article provides an overview and analysis of seismicity within the boundaries of the Arctic region for 2020 based on a consolidated catalog of earthquakes compiled from catalogs of the N. Laverov Federal Center for Integrated Arctic Research of the Ural Branch of the Russian Academy of Sciences, the Kola and Ya kutsk branches of the Geophysical Survey of the Russia Academy of Sciences (GS RAS), using data from the Seismological Bulletin of the GS RAS and the International Seismological Center. A total of 475 earthquakes are included in the consolidated catalog for 2020. Most of the earthquakes that occurred in 2020, including all the strongest earthquakes, were located within the mid-ocean ridges of Mon, Knipovich. Gakkel and Spitsbergen Fault Zone. In the offshore territories, most of the earthquakes were confined to the Svalbard archipelago, in particular, to the seismically active zone in the Sturfjord strait. Within the shelf areas, seismicity is also characteristic of the Novaya Zemlya archipelago, "continent-ocean" transition zone of the Barents-Kara region, Bely (Kvitøya) and Bear (Bjørnøya) Islands. For 17 earthquakes, the focal mechanism parameters are presented according to the Global CMT catalog.
