Correlation between large-scale motions in the liquid core of the Earth and geomagnetic jerks, earthquakes, and variations in the Earth’s length of day

We consider the correlation between seismicity, variations in the length of day, and geomagnetic jerks. We found that the jerks precede with in-phase variations in the number of strong earthquakes with М > 6.5 and the rate of the length of day in the range of periods of 5–8 years.
