Catalogue is prepared according to the earthquake data for the Arctic Basin region
published in the year-books "Earthquakes in the USSR in 1962-1991"
(Ed. N.Kondorskaya) and "Earthquakes of the Northern Eurasia in 1992-2002"
(Ed. O.Starovoit) bringing out by the Geophysical Survey of RAS.
The data set contains the information on 978 events of the Arctic region
for the period from 1965 to 2002.
