A magnitude Mw (ISC) = 6.6 earthquake on October 14, 1908 in the Barents-Kara Sea region was the strongest in this region for the entire observation period. We performed earthquake relocation based on our compilation of all available seismological bulletins of the time that included data from the ISC-GEM (International Seismological Centre–Global Earthquake Model) project, the EuroSeismos project, the Geophysical Survey of the Russian Academy of Sciences and the Russian State Library. The relocation was performed using a modified generalized beamforming method based on the BARENTS travel time model. The epicenter was located in the estuarial part of the Franz Victoria Graben at the continent-ocean transition zone. According to our justification, an earthquake of such magnitude could well have occurred in the area of Franz Victoria Graben.
