EAST EUROPEAN PLATFORM. RUSSIAN PART

Abstract

It is reported that 22 stationary seismic stations, 2 arrays and 7 local seismic stations, located in the area of Novovoronezh and Kursk nuclear stations, monitor seismicity of the Russian territory of the East European platform (EEP). A new station Belogornoe with high registration class has been opened, which also belongs to the International Monitoring System for the Comprehensive Nuclear-Test-Ban Treaty (IMS CTBTO). The results of the microseismic noise study at the Pulkovo network stations and assessment of maximum distance of earthquake registration in the Voronezh crystalline massif are presented. In 2014, relatively strong earthquakes with М3.0 were not recorded on the Russian territory of the EEP. Weaker natural seismicity with M≤2 was recorded in Karelia and the border areas with Finland, near Kandalaksha Bay, near the Khibiny Massif on the Kola Peninsula and on the territory of the Voronezh Crystalline Massif. Observations of local networks near nuclear stations are aimed at updating the information on seismicity previously considered as an aseismic territory of the EEP. Man-made events were recorded in permanent quarries, the most powerful of them (M=3.1–3.3) were produced in the quarries on the territory of the Kursk magnetic anomaly.
