Low-Magnitude Seismicity of the Continent-Ocean Transition Zone in the Eurasian Arctic

Year: 2024

Type: article

Abstract: A significant increase in the number of seismic stations occurred in the Eurasian Arctic during the late 20th to early 21st century, which led to a decrease in the minimum magnitude of earthquake registration for some Arctic regions. One of the areas that have been until recently poorly studied in terms of low-magnitude seismicity includes the continent-ocean transition zone in the northern Eurasian shelf. An analysis of the monitoring performed using the seismic stations in operation in the Franz Josef Land and Severnaya Zemlya archipelagos complemented with data from the seismic stations on the Svalbard archipelago for the period from December 2011 to November 2020 made it possible to study the space-time patterns in the low magnitude seismicity at the continent-ocean transition zone. The most active features are the Franz Victoria and St. Anna grabens, and the Bely and Victoria High.
