variations in the Earth’s rotation rate

Migration of small earthquake sources in Garm region and irregularity of Earth's rotation

Spatiotemporal variations in location of earthquake sources at depths H≥14 km in the Garm region are analyzed. Purpose. The purpose of researches – to search of  relation between the velocity of the Earth’s rotation, variations in the fluid field and activity of the deepened seismicity. Methodology. We used analysis procedure non-stationary time series: the spectral-temporal, wavelet analysis, method based on the calculation of the structural function  and others. Results.
