Seismogenic Ancient Structures of the Center and North of the East European Platform

Аннотация

The location of earthquake epicenters in the central and northern parts of the East European Platform in 2009–2016 has been analyzed. The earthquake epicenters have been recorded by seismic stations of the Geophysical Survey of the Russian Academy of Sciences and using the Mikhnevo Small-Aperture Array of the Institute of Geosphere Dynamics, Russian Academy of Sciences. The results obtained are indirectly indicative of the seismic activity of the regional Riphean structures complicating the foundation surface and of their possible activation at present. The available data on the historical earthquakes also confirm their confinement to paleorifts. It seems appropriate to take into account the position of ancient aulacogens in assessing the seismic hazard of the East European Platform.
