The bottom of the Atlantic Ocean, has it been lowered?

he bottom of the Atlantic Ocean, ie the ocean floor, gives us the impression of being much lower than the rest of the oceans. We can clearly see in the image, where the black is proportional to the depth, that there is an area in the Atlantic Ocean who looks like to be much lower than the rest. We can observe that there are two lines between which the ocean floor has the look of having been lowered. The first line goes from Ireland to Canada and the second line is located between Africa, the side of the Ivory Coast, and French Guinea to the other side.

We know that the bottom of the Atlantic Ocean is among the oceans fund's the most volatile and it's not impossible that it could have behaved like a cheese soufflé. At least this is suggested by some scientists. Note that the currents of magma from the inner Earth have a upward movement in this place and it's not impossible that there is or was an accumulation of lava and gases in some places as in a volcanic caldera. According to these scientists, these accumulations have caused devastating volcanic eruptions, which allegedly resulted in the collapse of the bubble and which would be the explanation for the disappearance of Atlantis.

This is the hypothesis putted forward by Mr Otto H Muck, who had suggested that an asteroid would have caused such a collapse, as shown in the illustration below.

We can also consider another possibility: one in which the floor would have been depressed by the impact of a celestial body that has either been an asteroid or a comet. Because a sufficient great force, generated by the impact itself, could have pushed all the magma to the opposite side of the Earth.

An island, can it sink without leaving any trace?

An island, can it sink into nothingness without leaving any trace, is the question we should ask ourselves. It's certain that an island might possibly sink, it's in fact enough that the so said island is located between two tectonic plates, and the rock, which the island is composed of, being heavier than the magma which is below it. Then, it will be sufficient that the tectonic plates diverge momentarily enough so that the island will lose its support to make it sink. A small island could actually disappear in this way. Magma, which comes up at the same time that the island sinks, will cover it and forms a crust, below which the island would have disappeared. This assumption is valid only if the island has had time to sink before the magma solidifies. Thus, an island of larger size, especially one measuring several hundred kilometers and more, has no time sinking completely before the magma solidifies. Another kind of disappearance which happens very often to volcanic islands is the explosion of the volcano of which they are composed. The most frequent cases of this type of loss is that the explosion of the volcano they are composed of causes the collapse of the volcano, and in some less frequent cases, that of the island. An example of an island which has partly disappeared by such an explosion is Thera.

The other assumption, that of an island caught between two tectonic plates that would have sunk following a geological event, is the part of the mid-Atlantic ridge formed by the islands of the Azores. We can actually see that at the location of the Azores islands, three tectonic plates join. These islands appear to be held in a pincer movement by the American, Eurasian and African tectonic plates.

The question of an island that could disappear without leaving a trace, is thus not easy to answer. The smallest of them could actually have done so. But this is quite different for the largest of them and those that have exploded: they should have left at least a trace of any kind. We should therefore have a trace of Atlantis somewhere, taking into account that this island would have had at least the size of North Africa and the Middle East of today together.

Where did all the matter go?

Where did all the matter go, seems to be a trivial question. But as we have seen previously, an island can sink only on the condition that the same amount of magma, which is below it, comes up in the same time. Plato had spoken of an island of an estimated size of several million square kilometers. The matter which should have come up this case, would have amply covered the whole of Europe with a layer of several hundred meters. Mr Otto H Muck had advanced the idea that magma rising up in the form of volcanic ash, would have fallen down back with the rains. According to him, Otto Muck H thus, the layers of Loess that we find from the French Atlantic coast to the Pacific coast of China would likely come from the disaster. It's certain that at least part of the magma had been moved in this way there. But the fact that the entire floor of the Atlantic Ocean appears to have been lowered, suggest us that most of the magma hasn't been moved up since the amount of Loess is not sufficient to explain the lowering of the Atlantic Ocean floor. Then the volcanic debris found so far aren't in sufficient quantities on the bottom of the Atlantic Ocean. We can therefore assume that a large amount of magma has been moved down, or even aside by an important mechanical force coming from the outside.

Before looking further, we should realize that the amount of magma that would have been displaced by a disaster, still largely exceeds ten million-cubic kilometers. To understand the importance of the phenomenon, just imagine that this amount would be sufficient to cover the Eurasian tectonic plate with a layer of several hundred meters. Although the Loess is there in an important quantity, it could never explain the lowering of the North Atlantic Ocean floor. There are certainly traces of volcanic material on the floor of the ocean, but again we don't find them in sufficient quantities. Among these there are traces we find some kinds of balls that could only have been formed in the open air, which would have meant that the magma had not solidify thousands of meters below sea water, but in the open air before being on the ocean floor.

Conclusion:

Even without excluding any hypothesis, we can take the one which is most obvious. It's likely that there would actually have been an accumulation of lava and gas below the ocean floor, but not so much that this could explain the descent of the ocean floor of thousands of meters. The ocean floor has certainly been lowered by a brutal force. Then when the impact occurred, the faults that had opened and a significant amount of lava, gases and ash escaped. But the volcanic ashes, which ended up falling, are not enough to explain alone the collapse of the ocean floor. We thus have a combination of these two cases: pushed down by a brutal impact of a celestial body, followed by the escape of ash, gas and volcanic lava.
