Свойства, вариации вращения и сейсмичность Земли

Short analysis of “critical latitudes” occurrence on slowly rotating planet was carried out. The basic connection of planet ellipticity with its angular rate of rotation was received, and the main concepts about spheroid weak pulsations were given. Bimodal distribution of the Earth seismicity which indicates clear connection of the planet seismic activity with the effect of “critical latitudes” was shown.
