Аnnotation: This article, continuing the study of the powerful event on 18th II.1772 in the north of the Kola Peninsula according to written sources about it [ Nikonov, 2020a], provides materials and analyzes several groups of natural processes in the epicentral area and adjacent areas in terms of natural manifestations of a seismic nature disturbances with arguments in favor of their occurrence as result of the earthquake of February 18, 1772. The groups include materials of a geophysical profile-section along the seabed north of the Cape Pogan-navolok, changes in the nature of fresh accumulations of debris at the bottom along the Murman coast to west of the Cape Pogan-navolok, section on the eastern coast of the Kola Bay. Signs of seismic disturbances in all groups are quite consistent with the event of 1772 and, thus, allow an increase in the number of points with estimates of the strength of shaking by VI-VII points independent of written data (in the article in 2020 there were only 2 points - the settlement of Kola and cape Trash-pillow (Pogan-navolok) at the NW exit from the Kola Bay...
