Abstract
In this work, we study the splitting of the lowest frequency 0S2 of the Earth’s free oscillations in the Earth’s electromagnetic field during large earthquakes. The work analyzes the results of electromagnetic monitoring at the Mikhnevo geophysical observatory of Sadovsky Institute of Geosphere Dynamics of Russian Academy of Sciences (54.96° N, 37.77° E), carried out using a LEMI-008 magnetometer (magnetic field components) and INEP fluxometer (vertical component of electric field). The estimates of the 0S2 singlet frequencies, obtained from experimental data on the detection of magnetic and electric fields, are determined with sufficiently high accuracy and have values rather close to theoretical ones. The theoretical frequencies are calculated by the Earth model 1066A.
