Abstract
First part of the paper deals with obscure imagination of mantle
convection, which contradicts to any real observations. Geological maps
clearly show plates rotation round South Pole and the opening of
back-arc basins confirms plates westward movements. Common action of
equator-fleeing force and tidal friction facilitates the plate movement
westward and northward. Hotspots confirm plate movements and triple
junction mantle convection excludes. Calculated north-south tidal
torques and tidal friction torques state when earthquakes by tides can
be triggered. Plate movement and earthquakes triggering are bound to the
space released by subduction. Not all Full or New Moons are favorable
for earthquake triggering; discarding can be caused by low tidal torques
or Moon and Sun torques acting oppositely. For Earth’s rotation
variations and for the plate movement the nodal Moon 18.61 years
periodicity, sidereal Moon 27.56 days periodicity and their semidiurnal
variations are important for earthquake triggering and earthquakes
prediction.
