In 1980 in the northwestern part of Ladoga and southwestern Karelia the production and geological association Sevzapgeologia and the Problem Research Laboratory of geological and geophysical studies of the Baltic Shield of the G.V.Plekhanov Leningrad Mining Institute conducted deep seismic studies by methods of deep seismic sounding and exchange waves from distant earthquakes (MOB3) along the profile and the Problem Research Laboratory of Geological and Geophysical Research of the Baltic Shield of the Leningrad Year Institute named after G.V. Plekhanov conducted depth seismic studies by methods of depth seismic sounding (DSS) and exchange waves from distant earthquakes (MOVZ) along the profile of Lahdenpokhya - Lake Segozero, which is hereinafter referred to as the Priladozhsky ...
In 1976-1979, the production and geological association Sevzapgeologia and the Problem Research Laboratory of Geological and Geophysical Research of the Baltic Shield of the Leningrad Mining Institute performed depth seismic surveys (DSR) in Central Karelia along the profile of the city of Kem - Lake Tulos, which is a continuation of the international geotraverse I, passing from the Alps to the Baltic Shield through the territories of the FRG, Czechoslovakia, Poland and the USSR ...
A large volume of regional seismic studies has been carried out on the Baltic Shield in order to study the peculiarities of the crustal structure. Observations were carried out in areas of development of various complexes of crystalline metamorphic and magmatic rocks.
In 1968, a seismic station with intermediate magnetic recording POISK-1-48-KMPV-OV was introduced into the practice of regional seismic works on the Baltic Shield. The use of magnetic recording made it possible to analyze seismic materials in laboratory conditions in order to decipher the interference sections of the wave field for a more reasonable correlation of the main waves in the interference zones.
