Brief Description: This catalog is the result of many years of research focused on recalculating earthquake parameters in the Eurasian Arctic for the period 1900–1961. Relocation was performed using the most comprehensive dataset available, a modern global velocity model, and a location algorithm adapted for early instrumental earthquakes. Different magnitude types were homogenized to a unified moment magnitude scale (Mw). In addition, a separate catalogue of events excluded due to insufficient data or inconsistency with the study area was compiled.
