Upsurge in big earthquakes predicted for 2018 as Earth rotation slows

The big title on the Guardian caught my attention, so I started reading it until my eyes caught up with the paragraph that reads  “Exactly why decreases in day length should be linked to earthquakes is unclear although scientists suspect that slight changes in the behavior of Earth’s core could be causing both effects.” If what I introduced earlier on Earth Magnets and Earth Spin Speed pages of this site, are proven to be true, then the answer to the scientists should be simple.

The outer Inner Core; a permanent magnet, is a ductile matter under the extreme pressure and temperature. Its poles are not located on opposite direction on the surface of Earth. Due to pulling/ pushing forces of other planets’ magnets, the poles are shifting; in a phenomena that scientists had called “wandering poles” . A sudden shift could trigger two  events:

  1. 1- Ripples in the Outer Core, that echo through the Inner and Outer Mantle and Crust, and cause tremors, some of which at high magnitudes, specially close to fault lines.
  2. 2- Change of the angle that separates the permanent magnetic field force lines and the electrons flowing at right angle to the axis of rotation at the inner shell of the Inner Mantle. The Lorentz Force that is created there follows the electromagnetic left hand rule, and brings the Earth to spin in anticlockwise direction. Any change in the angle would influence the strength of Lorentz force in the direction perpendicular to the electrons flow’ direction. At right angle Earth gets the highest Lorentz Force and therefore the highest spin speed. Any degree lower than right angle reduces the Lorentz Force that consequently bring a slow down to the Earth spin speed.
