Abstract:
The article provides an overview and analysis of seismicity within the boundaries of the Arctic region for 2016–2017, a description of seismic station networks, and processing methods. The catalog of earth-quakes in the Arctic region was compiled on the basis of catalogs of several organizations and seismological centers. In total, 875 earthquakes are included in the earthquake catalog. Most of the earthquakes that occurred in 2016–2017, including all the strongest earthquakes, were located within the mid-ocean ridges of Mon, Knipovich. and Gakkel. 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 character-istic of the "continent-ocean" transition zone of the Barents-Kara region. Most earthquakes within the transition zone are confined of the trenches. For 39 earthquakes, the focal mechanism parameters are presented according to the Global CMT catalog.
