Distribution of Seismicity and Heat Flow Anomalies in the Barents Sea Region

Abstract

The contemporary seismicity and heat flow density are indicators of geodynamic processes. A unified seismic catalog is compiled for the European sector of the Arctic region for the period of 1995–2015 with the data on the spatial distribution of heat flow from different databases. The theoretically possible relationships of heat flow values and seismic activity manifestations are discussed for this region, and combined geological and geophysical cross sections of the structure of the lithosphere are made in the latitudinal and meridional directions. The most geodynamically active structures and zones of tectonic stress concentration are distinguished.
