The mysterious underwater structures at Yonaguni

April 5, 2010

Yonaguni Island is a part of Japan’s Ryukyu archipelago. In 1986 under the water around it were discovered what some people say are the ruins of an ancient civilization and others believe it is only natural formations.

Masaaki Kimura is a geologist for Ryukyu University. He has studied the site (also known as Yonaguni Monument) for the past 15 years. He believes that the underwater rocks are the remains of a city 5,000 years ago. It is based on the dating of stalagmites found in caves that collapsed while the city alleged.

He claims to have found marks and symbols carved into the stone and also rocks carved with animal forms. He has also identified ten structures in Yonaguni and five more similar structures on the main island of Okinawa. The ruins cover a 300 x 150 meters area.

The structure include the ruins of a castle, a triumphal arch, five temples and at least one large stadium, connected by roads and waterways and protected in part by what could be huge walls. The largest structure is a monolithic pyramid, which rises to a depth of 25 meters.

The city sank 2000 years ago in one of the major earthquakes that hit this part of the Pacific Ocean. In fact, on 4 May 1998, a part of the island and the ruins were destroyed by an undersea earthquake.

But not everyone believes as Kimura. Robert Schoch, professor of science and mathematics from Boston University, is convinced that none of the stone structures is the work of human hands. He said these geological formations are well known and they’re specific to a region with seismic activity.

I wonder if it's the remains of a meteor impact. The way the huge rocks have been pushed up as the meteoric rock pushed along the sea base, the softer parts now gone behind the ' monument' with only the harder rock that was pushed up still there.

The thought that a meteoric imapct or smaller pieces falling, in that area is not that odd, Sodom and Gomorah, there are also circular rings at the end of the Dead Sea.

The way the rock faces are showing sounds also like meteoric impact. The below photo is from the crater of Kaali impact in Saaremaa, Estonia.

Massive submerged structure stumps Israeli archaeologists

The massive circular structure appears to be an archaeologists dream: a recently discovered antiquity that could reveal secrets of ancient life in the Middle East and is just waiting to be excavated.

It's thousands of years old -- a conical, manmade behemoth weighing hundreds of tons, practically begging to be explored.

The problem is -- it's at the bottom of the biblical Sea of Galilee. For now, at least, Israeli researchers are left stranded on dry land, wondering what finds lurk below.

The monumental structure, made of boulders and stones with a diameter of 230 feet, emerged from a routine sonar scan in 2003. Now archaeologists are trying to raise money to allow them access to the submerged stones.

"It's very enigmatic, it's very interesting, but the bottom line is we don't know when it's from, we don't know what it's connected to, we don't know its function," said Dani Nadel, an archaeologist at the University of Haifa who is one of several researchers studying the discovery. "We only know it is there, it is huge and it is unusual."

Archaeologists said the only way they can properly assess the structure is through an underwater excavation, a painstakingly slow process that can cost hundreds of thousands of dollars. And if an excavation were to take place, archaeologists said they believed it would be the first in the Sea of Galilee, an ancient lake that boasts historical remnants spanning thousands of years and is the setting of many Bible scenes.

In contrast, Israeli researchers have carried out many excavations in the Mediterranean and Red Seas.

Much of the researchers' limited knowledge about this structure comes from the sonar scan a decade ago.

Initial dives shortly after that revealed a few details. In an article in the International Journal of Nautical Archaeology published earlier this year, Nadel and fellow researchers disclosed it was asymmetrical, made of basalt boulders and that "fish teem around the structure and between its blocks."

The cone-shaped structure is found at a depth of between three and nine and 40 feet beneath the surface, about 1,600 feet from the sea's southwestern shore. Its base is buried under sediment.

The authors conclude the structure is man-made, made of stones that originated nearby, and it weighs about 60,000 tons. The authors write it "is indicative of a complex, well-organized society, with planning skills and economic ability."

The rest is a mystery.

Yitzhak Paz, an archaeologist with the Israel Antiquities Authority who is involved in the project, said that based on sediment buildup, it is between 2,000 and 12,000 years old, a vast range that tells little about it. Based on other sites and artifacts found in the region, Paz places the site's origin some time during the 3rd millennium B.C., or about 5,000 years ago, although he admits the timeframe is just a guess.

"The period is hard for us to determine. No scientific work was carried out there, no excavations, no surveys. We have no artifacts from the structure," Paz said.

Archaeologists were also cautious about guessing the structure's purpose. They said possibilities include a burial site, a place of worship or even a fish nursery, which were common in the area, but they said they wanted to avoid speculation because they have so little information.

It's not even clear if the structure was built on shore when the sea stood at a low level, or if it was constructed underwater. Paz reckons it was built on land, an indication of the sea's low level at the time.

In order to fill in the blanks, archaeologists hope to inspect the site underwater, despite the expense and the complexities.

Nadel noted that working underwater demands not only a skill such as scuba diving, but also labor-intensive excavations that are particularly difficult in the Sea of Galilee, which already has low visibility and where any digging can unleash a cloud of sediment and bury what's just been uncovered.

Also, divers can remain under water only for a limited amount of time every day and must choose the best season that can provide optimal conditions for excavating.

"Until we do more research, we don't have much more to add," Nadel said. "It's a mystery, and every mystery is interesting."

The mysterious underwater structures at Yonaguni

But not everyone believes as Kimura. Robert Schoch, professor of science and mathematics from Boston University, is convinced that none of the stone structures is the work of human hands. He said these geological formations are well known and they’re specific to a region with seismic activity.

Natural formation

Some of those who have studied the formation, such as geologist Robert Schoch of Boston University, state that it is most likely a natural formation, possibly used and modified by humans in the past. Schoch observes that the sandstones that make up the Yonaguni formation "contain numerous well-defined, parallel bedding planes along which the layers easily separate. The rocks of this group are also criss-crossed by numerous sets of parallel and vertical (relative to the horizontal bedding planes of the rocks) joints and fractures. Yonaguni lies in an earthquake-prone region; such earthquakes tend to fracture the rocks in a regular manner." He also observes that on the northeast coast of Yonaguni there are regular formations similar to those seen at the monument. Schoch also believes that the "drawings" identified by Kimura are natural scratches on the rocks. This is also the view of John Anthony West. He also suggests that walls are simply natural horizontal 'platforms' which fell into a vertical position when rock below them eroded and the alleged roads are simply channels in the rock.

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 in the Sanninudai slate cliffs above, which have "been fashioned solely by natural processes," and concludes in regard to the underwater structures that "there seems no reason to suppose that they are artificial."
