Seismological Data

Earthquake catalogue of the western sector of the Arctic zone of the Russian Federation
The catalogue is a combination of earthquake data from the regional catalogues (Arctic and East European Platform) of the Unified Geophysical Service of the Russian Academy of Sciences (FRC EGS RAS), the catalogue from the article [Morozov et al., 2023] and data from the International Seismological Center ISC Bulletin on the territory limited by coordinates:
                        60°N, 25°E;   84°N, 25°E;   84°N, 100°E;   60°N, 100°E.

Catalogue contains information on 4,629 seismic events for the period 1963–2022.
For the period 1998–2020, when all “non-earthquakes” have been removed with a high degree of confidence,
the directory contains 2,126 entries.

The catalogues were merged according to the author's method that is described in "Nearest Neighbor Method for Discriminating Aftershocks and Duplicates When Merging Earthquake Catalogs"
by Vorobieva I.A., Gvishiani A.D., Dzeboev B.A., Dzeranov B.V., Barykina Yu.V., Antipova A.O.
Frontiers in Earth Science. 2022. Vol. 10. DOI: 10.3389/feart.2022.820277.

A detailed description of the earthquake catalogue of the western sector of the Arctic zone of the Russian Federation is given in the article "Integrated Earthquake Catalog II: The Western Sector of the Russian Arctic"
