Abstract

Typical paleoseismic dislocations have been detected by field observations in the Kola Peninsula. The map of ancient earthquake epicenters was compiled on the basis of geological data and aerial photograph interpretation. The epicenters mainly concentrate in the west and in the center of the Kola Peninsula in the area, which has been occupied by active ice during the Older and Younger Dryas or near the distal side of the Older Dryas marginal ridges. The increase of seismotectonic activity took place after deglaciation of the territory owing mainly to crustal deformation caused by glacioisostatic uplift, which is going on until now.
