Seismological Data

Earthquake catalog of the Arctic zone of the Russian Federation
(including the Gakkel Ridge, Knipovich Ridge and Svalbard archipelago)
The catalog is a combination of earthquake data from regional catalogs of the Geophysical Survey of the Russian Academy of Sciences (GS RAS) (Yakutia, Northeast Russia, Kamchatka, Arctic, East European Platform and Svalbard), the catalog of FCIAR network (station network of FECIAR UrB RAS), the catalog from [Morozov et al., 2023] and the International Seismological Center ISC Bulletin.

Catalog contains information on 45,793 seismic events for the period 1962 2022.

The catalogs 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.
