Abstract. The article presents new preliminary data on Holocene seismic dislocations obtained as a result of field palaeoseismic geological works in the area of the northern coast of the Kandalaksha Bay of the White Sea (Kola Peninsula, northwestern Russia). Local Late- and Postglacial relief disturbances and rock displacements resulting from strong seismic impacts are considered. We present data indicating dynamic (seismic) impact on rocks. According to the complex of geological and geomorphological features in the area of Cape Zimets the area of concentration of seismic dislocations, which occurred repeatedly in the Late Glacial and during the Holocene, was identified. The studied seismic dislocations belong to the tectonic zone of north-eastern extension, transverse to the main structures of the Kandalaksha graben, the activation of which occurred in the late Holocene.

Keywords: palaeoearthquakes, seismic dislocations, Kandalaksha Graben, Kolvitsky Graben, White Sea, Holocene, Kola Peninsula, Fennoscandian Shield
