Seismological Data

Earthquake catalog of 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) (Arctic 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 for the territory limited by the coordinates:
75°N, 10°W;   88°N, 10°W;   88°N, 140°E;   77°N, 140°E;   77°N, 100°E;   84°N, 100°E;   84°N, 25°E;   75°N, 25°E.

Catalogue contains information on 17,992 seismic events for the period 1962 2022.

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 catalog of the Gakkel and Knipovich ridges, as well as the Svalbard archipelago, is given in the article "Integrated Earthquake Catalog. III. Gakkel Ridge, Knipovich Ridge and Svalbard archipelago" by Vorobieva I.A., Gvishiani A.D., Shebalin P.N., Dzeboev B.A., Dzeranov B.V., Sergeeva N.A., Kedrov E.O., Barykina Y.V. Appl. Sci. 2023, Vol. 13. Is. 22. (SI: Geoinformatics and Data Mining in Earth Sciences). 12411.
