Investigation of the relationship between strong earthquakes and the planetary precession within the limits of the rotational earthquake model yielded the following results. (1) The planetary precession is caused by zero oscillations generated by the seismotectonic process in the upper lithosphere. (2) Chandler's frequency splits into f_{ch 1} = 0.835 year^-1 and f _{ch 2} = 0.860 year^-1, as the values of zero frequencies for the N-S (Pacific) and W-E (Alps Himalayas) oriented seismic belts are different. (3) The distribution of radius values of pole paths according to their number has a regular component 0''.05, which is equal to the seismotectonic energy released in the foci of strongest earthquakes. The relation between the solar activity and seismotectonics is hypothesized to be the result of interaction between the yearly precession component and two Chandler's frequencies.
