In the presented paper the subject of tectonic activity estimation on the Earth’s surface and on faults in areas of nuclear power plants on the base of geodetic data is continued [12]. At the power plant of Ignalinskaya there was no geodynamic test-site, so the data was collected by high-precision re-leveling in its vicinities (Lithuania, Latvia and north-western Belarus) from which the location of tectonic activity was determined on the background of the InPP’s entire regional geodynamics.
