Аnnotation: Detailed paleoseismogeologic, morphotectonic and tectonophysic studies using remote and ground surveys were carried out on the islands of the Kuzokotsky archipelago, located on the south coast of the Kandalaksha Bay of the White Sea. The following have been established: a) kinematic parameters of seismic ruptures, including strike-slip faults, reverse strike-slip faults of the general (NNW) direction corresponding to the onboard structures of the Kandalaksha graben and strike-slip faults, normal strike-slip faults, extensional faults of the WNW direction corresponding to the structures of the graben of the Great Salma; b) the correspondence of the parameters of seismic ruptures to periodic changes in the field of tectonic stresses from NW to NE compression; c) the inheritance of seismic deformations and the development of the latest morphostructure within the framework of the dominance of the structures of the Kandalaksha graben with periodic activation of the Velikaya Salma graben; d) three main stages of seismogenic renewal, including: I – pre-Glacial and the beginning of the Late Glacial; II – Late Glacial period; III – Holocene; e) three main seismic episodes in the Late Holocene: 2.3–2.2 k.y. BP; 1.5–1.4 k.y. BP and 0.5–0.4 k.y. BP; f) traces of maximum concussions corresponding to IX+ and X points, localized along the outer northern (Great Salma) flank of the archipelago and related to all stages of seismogenic renewal.
