The catalog 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.
contains information on 23,254 seismic events for the period 1962–2020.
The catalogs were merged according to the author's method that is described in
Vorobieva I.A., Gvishiani A.D., Dzeboev B.A., Dzeranov B.V., Barykina Yu.V., Antipova A.O.

A detailed description of the earthquake catalog of the eastern sector of the Arctic zone of the Russian Federation
is given in the article that will be published soon in the journal
Catalog format (text format with TAB separator):
9. Depth (not known for all earthquakes)
10. Author's magnitude
11. Energy class
12. Event ID from source catalog (if known)
13. Agency/source catalog
14–16. Agency-Type-Magnitude selected to determine the author's magnitude.
If there is no data, then the author's magnitude was determined by the energy class.
