Mystery and Truth of Underwater Ruins

The massive rock structures that stretch across the seafloor of Yonaguni Island are commonly referred to as "underwater ruins," but at this time they have not been determined archaeologically to be man-made ruins.
More precisely, the "Undersea topography that looks like ruinsThe neutral understanding is to view it as a "natural landform". Therefore, there are both man-made and natural geomorphic theories regarding this seafloor topography, and the debate continues to this day.
There is no conclusive evidence for either theory,No clear conclusion has been reached.The following is a list of the most common problems with the "C" in the "C" column.
That is why the undersea topography of Yonaguni Island continues to attract divers and researchers from around the world as a "mysterious entity that cannot be determined whether it is a ruin or nature.
artificial theory
The evidence for the artifact theory can be cited as,Terraced terrain with walls that appear to be right-angled and wide flat surfacesIt is.
Although the site is on the sea floor, the continuous shapes of the formations look as if they were cut and shaped from stone, leading some to believe that it is difficult to believe that the formations were formed by nature alone.
Another evidence is the wedge-shaped pit found on the rock face.
There are areas that appear to be regularly lined up, and if they are processed by human hands,Traces of quarrying and constructionIt is believed that this is not the case.
natural geomorphology
On the other hand, in the natural topography theory,Erosion of waves and currents over many years along fracture-prone directions (nodules) in the bedrockThis explains the formation of terrain that appears stair-stepped or linear.
Another rationale is that the entire topography is tilted approximately 10-15 degrees to the southeast, which is consistent with the dip of the Yaeyama fault zone.
While this is an unnatural inclination for man-made structures, it is easier to explain for natural landforms that follow the geological structure.
It has also been pointed out that the areas that look like a pit may have been caused by erosion or biological activity.
These points make this submarine topography all the more mysterious because the features that appear manmade are not necessarily evidence of human handiwork.
