During the hour of the pole shift, when the crust of the Earth is being dragged along with the core such that the Earth's North Pole is turning away from the North Pole of the 12th Planet, and the Earth's South Pole pulling up to face it, several things are happening at once. A synergy, or play-off, therefore occurs. The stage is set by what occurs during the days preceding the pole shift, when the Earth's rotation slows and then stops, within a day, and stands with her mid-Atlantic ridge facing the Sun where her brother, the 12th Planet, is passing. During these few days (less than a week) when rotation has stopped, the waters of her oceans flow toward the poles and away from her fat equator. An equalization occurs, the waters settling evenly, where normally the rotation pulls the water by centrifugal force to where the motion is fastest, at the equator. Thus, when the pole shift itself occurs, the oceans have pulled away from the tropical shores and flooded the frozen poles.
Tidal waves are caused by several factors, but to those living along the coasts, the effect is the same. When the Earth rolls her North Pole away from the Sun and the passing 12th Planet, the water resists, and thus there is flooding where the oceans meet moving land, and a drawing away of the oceans from those shores on the opposite side of a land mass which is pulling away from the stagnant ocean water. However, for the most part, the oceans move with the land as one. When the motion stops, the water, not being attached to the core as the crust is, fails to put on the brakes and continues its motion, and thus tidal waves occur where only hours before the water had drawn away from the shores. A third factor affects the height and force of tidal waves, and that is the movement of plates where the bowl that holds the ocean water may become larger or smaller.
Where this analysis of water movement might seem astonishing, given that the Atlantic and Pacific oceans will equalize in size during this next pole shift, the reader should bear in mind that the Pacific will already be low on the coasts along her equator due to the waters movement toward the poles when rotation stops for several days. Finding the oceans in the Pacific more full, relatively speaking, the water at the poles will pour into the Atlantic or Indian Ocean, in preference to pouring into the Pacific. And then the broad expanse of the Pacific can absorb any shrinking of the Pacific bowl, as each acre of ocean takes its share of the rise, lessening the effect on the shores.
The speed and force of water movement is influenced by many factors. Look to how long it takes a flood to travel from the highlands to the sea - days, and even weeks in some places. Water seeks its level and moves, but until there is sufficient pressure, it moves relatively slowly, creating eddies and ripple currents, then waves, and only under extreme pressure, shooting water pushing everything in its path aside. During the stopped rotation, the movement of water toward the poles is gradual, and has barely begun before the pole shift and restarting of rotation occur. Likewise, water settling around the new equator happens over a period of weeks, and due to the large expanse of oceans along the new equator, this additional water is distributed so that the effect on land along the new equator can be measured in feet.
