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
