Аннотация: Abstract—Detailed paleoseismogeological, morphotectonic, and tectonophysical studies using remote and ground surveys have been carried out on the islands of the Kuzokotsky Archipelago on the southwestern coast of Kandalaksha Bay of the White Sea. The following have been established: (a) kinematic parameters of seismic ruptures (including strike-slip faults; overthrust strike-slip faults along the ruptures of the general(NNW) direction corresponding to the side structures of the Kandalaksha graben; and strike-slip faults, faults, and tear faults along the ruptures of the WNW direction corresponding to the structures of the Velikaya Salma graben); (b) the correspondence of seismic rupture parameters (reverse strike-slip faults) to periodic changes in the tectonic stress field from northwest to northeast 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 the periodic activation of the Velikaya Salma graben; (d) three main stages of seismogenic renewal: (I) preglacial and the beginning of the late glacial, (II) late glacial, and (III) Holocene; (e) three main seismic episodes in the Late Holocene: 2.3–2.2, 1.5–1.4, and 0.5–0.4 ka BP; and (f) traces of maximum shaking corresponding to the IX+ and X seismic scale localized along the outer northern (Veliko-Salmian) flank of the archipelago and related to all stages of seismogenic renewal.
