Seismological Data
Earthquake catalog of the Arctic zone of the Russian Federation
(including the Gakkel Ridge, Knipovich Ridge and Svalbard archipelago), 1962 – 2024
|
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 53,777 seismic events for the period 1962 – 2024.
The catalogs were merged according to the author's method that is described in
