Vortex hypothesis of earthquakes.

The western transfer of the atmosphere rotates the crust, the crust rotates the mantle.

At the equator, the speed and friction of the crust of the Earth is more than in the temperate belts, due to which mesoscale eddies are formed in the mantle by precessing reflecting tidal wave.

This hypothesis can be easily verified with the help of a simple experiment: if you rotate a round glass jug with a thick clear liquid and sawdust.

***********************************
The magnitude of the precession of sea eddies in the northern hemisphere depends on the inclination of the earth’s axis, the axial and orbital velocity of the earth. The highest orbital velocity of the earth occurs in perihelion at the beginning of January in the new moon phase.
In the seas, in the northern hemisphere, at this time the highest tides are formed (at night).
It is possible that most earthquakes in the northern hemisphere occur in early January in the new moon phase, at night.
And in the southern hemisphere, at this time, earthquakes should occur less.
