Seismological Data

Earthquake catalogue of the eastern sector of the Arctic zone of the Russian Federation
The catalogue is a combination of earthquake data from regional catalogs of the Geophysical Service of the Russian Academy of Sciences (GS RAS (Yakutia, Northeast Russia and Kamchatka) and the International Seismological Center ISC Bulletin for the territory limited by the coordinates:
          60°N, 100°E;   77°N, 100°E;   77°N, 165°W;   57.5°N, 165°W;   57.5°N, 138°E;   60°N, 138°E.

Catalogue contains information on 23,254 seismic events for the period 19622020.

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 eastern sector of the Arctic zone of the Russian Federation is given in the article "Integrated Earthquake Catalog of the Eastern Sector of the Russian Arctic"
by Gvishiani, A.D.; Vorobieva, I.A.; Shebalin, P.N.; Dzeboev, B.A.; Dzeranov, B.V.; Skorkina, A.A.
