The Loss and shift of the Magma through subvolcanism, Volcanism and Supervolcanism to Cavities and Calderas on the Crust and Pockets on the Asthenosphere, greatly weakens the Core's magnetational pull, resulting to magnetetional interference and Pole shifts, consequence of excessive variation. General fragmentation is pending, because the core will not be able to hold the fragmented chunks or (tectonic plates together). We are pretty close to that point. I offered solution to the deaf.
