Seismotectonics of the Russian Segment of the Arctic

Abstract

The study examines the foci of the strongest earthquakes in the Russian segment of the Arctic, which have occurred over the entire period of observations, starting from 1976 to the present. The stress and strain fields have been studied through the analysis of the seismic moment tensor of the registered earthquakes. This analysis is conducted for the first time. Spatial distributions of the Lode–Nadai coefficient and the rate of seismotectonic strain have been obtained.
