Analysis of Geophysical Data to Highlight Areas of Possible Earthquakes in the Eastern Margin of the East European Platform

Yu. V. Baranov

Abstract


The article considers the possibility of applying the ratio of the anomalous magnetic and gravity fields for determining zones of the possible earthquakes in seismically quiet region. Correlation between the normalized anomalous magnetic and gravity fields (admittance) and location of earthquake's epicenter at the Eastern margin of the East European platform and the Urals was found. Analysis of geophysical data and applying of admittance allow obtaining additional detailed information about seismicity of the region.
