文摘

Recently, Izvestiya, Physics of the Solid Earth has published the empirical results certainly indicating the influence of the free oscillations of the Earth on earthquake activity. It is known that free oscillations are excited by the earthquakes. Therefore, we may hypothesize that the Earth experiences self-excited oscillations. In this paper, it is shown that the very fact that free oscillations affect global seismicity does not necessarily mean that resonant self-excited oscillations of the Earth do exist. At the same time, the signs of selfexcited relaxation oscillations are in some cases probably observed in the form of hidden periodicity with a quasi period of ~3 h in the aftershock sequences from the strong earthquakes. The further research on this subject appears to be promising. Keywords earthquake spheroidal oscillations seismic waves round-the-world echo
