Underwater rock formations resembling a pyramid found off Yonaguni Jima Island in the Ryukyu Islands of Japan may represent the Asian version of Atlantis according to Masaaki Kimura, a marine geologist at the University of the Ryukyus in Japan.
On the other hand, Robert Schoch, a professor of science and mathematics at Boston University claims "It’s basic geology and classic stratigraphy for sandstones, which tend to break along planes and give you these very straight edges, particularly in an area with lots of faults and tectonic activity."
The Japanese government has taken a hands-off approach, leaving the arguments to the academic community to make a determination as to whether the formation is man-made or natural.In the meantime this will become an underwater tourist attraction to rival the Bimini Road as a controversial ancient man-made ruin or natural rock formation.
This is one for the Fylde and Wyre Antiquarian expert to debunk. I'm keeping an open mind. Geology does produce straight lines and other strange shapes like the Giant's Causeway between Britain and Ireland. This looks a little too architectural though and I'll be looking for further developments.
