Abstract. The territory surrounding Lake Srednee Luvengskoye, as well as its bottom, is being studied. The methods of geological and geomorphological descriptions, depth sounder measurements, aerial photography from UAVs, georadar profiling on land and water areas, cataclastic analysis of discontinuous displacements and structural paragenetic analysis of geological stress indicators were used. For the first time, a bathymetric map of this lake has been compiled. The conducted complex of studies allows us to conclude that there is an interconnected block-fault system here, expressed in fractures of the crystalline basement, deformations of loose sediments and surface structure, indicating inherited displacements along the faults before the Late Glacial and, probably, the Holocene. It was found that the contrast of the relief, the differentiation of the section within the lake bottom and the identified stress indicators in the coastal zone indicate the location of the axial part of the fault zone along the lake basin with maximum amplitudes in the southern part of the basin. Keywords: bathymetric map, block-discontinuous tectonics, geological stress indicators, GPR- profiling of the lake, seismotectonic observations, seismic dislocations, tectonic deformations, Kola Peninsula
