There are three cycles to the expansion of the Earth. The first, and most mild, is the gradual cooling of the core, causing a slow expansion, and minor volcanic and earthquake activity worldwide, as things re-settle.
The second is the intermediate speed matter from the inner core dropping into the low speed (1-x) range. This is not done in a smooth, continuous motion. A threshold is reached, then there is an avalanche effect that causes a great deal of matter to drop out of motion in time, back to motion in space. Take, for example, motion defined as s/t. A motion of 5 units, in time, would be defined as 1/5, or as it would appear in space, 0.20. When those 5 temporal units invert to become 5 units of space, 1/5 becomes 5/1—what was 0.2 meters, is now 5 meters—a major expansion in volume occurs at the core of the planet.
This causes the plates, world-wide, to separate and exposes the magma of the asthenosphere to whatever is above, typically water. With wide gaps between the plates sitting on the molten, slippery asthenosphere are free to move, in relation to each other, as well as over the mantle of the crust.
Because the Earth is rotating, the plates will seek the “least energy” configuration. The largest continental bulge will tend to become equatorial. In most cases, this is one of the polar ice caps, with ice piled miles high. Thus, the plates containing these ice caps will slide to equatorial positions, normally turning the surface of the Earth 90° from its prior position. This would be a regular, and predictable, phenomenon.
The final cycle of expansion is the “core flare,” when enough gas is produced in the center of the core (the low density area), to generate sufficient gas pressure to break through the inner core, and into the molten outer core, and explode—the core flare. This has a devastating effect on the surface of the planet. The thermal release will break through a section of the mantle, literally blowing a several-mile-wide volcano in the surface of the planet to release the pressure. Enormous quantities of material will be pushed to the surface, causing another sudden increase of surface area, but localized to a region, rather than distributed globally. This outburst would most likely coincide with the second cycle, but not always occur. Again, it would probably be at a fairly regular interval, with a number of Cycle 2 events occurring between.
The results of this core flare could split a section off a continent, and push it several hundred miles away from its parent in a matter of a few days.
Consider a tribe living in a coastal area, with a large island visible to the west. The core flare occurs, and volcanism and earthquakes flare up all around for several days. The activity dies down, and they look to their west, and see nothing but muddy waters of the ocean, bubbling with volcanic remnants. Their reasonable conclusions: the gods have gotten angry, and sank the island continent to the west. In reality, the coast was the fracture zone, and that island just moved over the horizon, where it can no longer be seen, and will probably continue to move rapidly for several decades. The volcanoes and muddy waters make it look like the continent had sunk; in reality, it just moved a great distance in a short time.
We find evidence of this in the legends of Mu, Atlantis, Lemuria, and “Ancient Lanka (Ceylon).” Ancient Lanka was supposed to exist off of the west coast of India, where a series of islands now exist. However, since the water levels were much lower then, those islands were part of the coastal mountains of India. The topography of the ocean floor at that point indicates only simatic crust—no continental mass. However, by following the fracture zones and stretch marks, the ancient island of Lanka can be found.
Lanka is also known by the name Lemuria, named after the Lemurs found in both India and Africa, but not in any of the intervening lands. It was assumed a land bridge once spread between Africa and India, allowing these creatures to cross freely. And so was the case. Consider:
“Because many of its animals, plants and rocks resemble those of Africa, some think that… was at one time connected to that continent. But it has also plants and animals seemingly of East Indian origin. This is the basis for supposing it to be a remnant of a continent called Lemuria, which is believed to have filled, in ages gone by, the central basin of the Indian Ocean."1
When the Earth’s size is reduced, as it was ages ago, an island does connect India to Africa—the island of Madagascar. Madagascar is Lemuria/Ancient Lanka. (The island seemed much bigger, then, because the Earth was smaller).
The same is true for Atlantis. Prior to the last major expansion, Antarctica was tropical and much closer to Africa and South America. North America was at the North Pole, and in an “Ice Age” (Ice Ages occur when the crust is reoriented so the place having the ice age is near one of the polar points). Antarctica is Atlantis. And Atlantis will “rise again,” when the next core flare occurs, as it now has the bulk of the elevated mass of the planet piled up in its ice sheets. When the crust slips, that bulk will become equatorial, and melt. However, all the remains of Atlantis are now crushed into sand, by the massive sheets of ice.
Continuing extrapolation shows that Mu was the continent of North and South America combined with Antarctica, just after the formation of the Pacific basin.2 The core flare formed the basin, and pushed Antarctica off of America, rolling it south. Those survivors in America saw the continent of the west disappear, leaving only mud and volcanism. But it really isn’t gone, just relocated.
