Abstract
Seismic observations by 48 stationary seismic stations, including twelve temporary seismic stations located in the area of Novovoronezh and Kursk nuclear power plants, were carried out on the Russian territory of the East European Platform. A feature of seismicity in 2018–2019 is a unique Kandalaksha earthquake of November 5, 2019 with ML=3.8 in the Belomorsky region. Its focal mechanism was represented by a normal fault. For the first time, a noticeable earthquake with МL=3.4 was recorded on September 5, 2019 at the Pashninskoye and Beregovoye fields in the Timan-Pechora oil and gas province. It was felt in Neftepechorsk working settlement with an intensity of up to 4 MSK-64. As before, weak natural seismicity was recorded on the Baltic Shield: in Karelia, in areas bordering Finland, near the Kandalaksha Bay, near the Khibiny and Lovozero massifs on the Kola Peninsula, on the Voronezh crystalline massif territory, especially in the zone of its junction with the DnieperDonetsk trough.
