Mu Yonaguni Ruins
In the 1980s, local divers discovered a striking underwater rock formation off the southernmost point of the island. This so-called Yonaguni Monument has staircase-like terraces with flat sides and sharp corners. Although the majority of the academic society regard the rock formation as natural joint, Masaaki Kimura, a professor of seismology in University of the Ryukyus and some media believe it is an artificial (or artificially modified) structure engraved or built 2,000 to 3,000 years ago.
Patrick D. Nunn, Professor of Oceanic Geoscience at the University of the South Pacific, has studied these structures extensively and notes that the structures below the water continue above and are slate that “has been fashioned solely by natural processes” and that “there seems no reason to suppose that they are artificial.”
