| Abstract: | We present results of detailed paleoseismological research at the key site on the flank of the Lake Imandra depression (Kola region, northeast of the Fennoscandian Shield). Study of various groups of paleoseismic deformations in the fault zone and application of new methods and approaches made it possible to recognize a segment of a large seismotectonic zone where violent earthquakes occurred repeatedly at the end of the Late Glacial and in the Holocene. The dates of earthquakes and the location of their foci are determined. |
