'Wind' from Earth's middle layer blows through a secret passage beneath...just like the Macuxi said.

A geological secret passage beneath Panama may explain why rocks from Earth's mantle are found more than 1,000 miles (1,609 kilometers) from where they originated. 



This opening, located some 62 miles (100 km) below Earth's surface, may allow a flow of mantle materials to travel all the way from beneath the Galápagos Islands to beneath Panama. 

This never-before-discovered form of transport may also help explain why Panama has very few active volcanoes. On the west coast of Central America, the Cocos tectonic plate is diving down and pushes oceanic crust under the continental crust of the North American, Caribbean and Panama tectonic plates, a process called subduction. This subduction zone creates a line of volcanoes called the Central American Volcanic Arc where lava pushes through the boundaries. But the volcanism stops in western Panama, which sits on the Panama plate , said David Bekaert, a postdoctoral scholar in marine chemistry and geochemistry at Woods Hole Oceanographic Institution in Massachusetts...



...Blowing in the (mantle) wind 

This was strange, because there was no clear way to explain how mantle elements from the Galápagos could get all the way to Panama, Bekaert said. The researchers then turned to seismic imaging of the mantle, which uses earthquake waves to map what's beneath the surface, and computer modeling to try to explain what might be going on.

They found that deep beneath Panama, the buried portions of the Cocos plate may hold the answer. When a tectonic plate slides under another tectonic plate during subduction, that subducting plate doesn't just disappear; it retains its structure as it grinds down into the mantle, only gradually heating and warping. 

"Just beneath Panama, there is a hole, a window through the slab, that allows for the influx of this mantle component," Bekaert said


This window may be the result of a natural, pre-existing fracture in the subducting Cocos crust, or it may be a place where the crust snapped during subduction. Either way, it lets materials pass through — from one side of the plate to the other — like a breeze through an open window.

That left the question of what might be driving the breeze. The researchers found two possibilities. The first is that the materials are moving through the Panama Fracture Zone, a zone of cracking in the crust and upper mantle that connects the Galápagos to Panama . But it's difficult to see what would drive long-distance transport through that zone, Bekaert said.

The Macuxi Indians are Indians living in the Amazon, in countries like Brazil, Guyana and Venezuela. According to their legends, they are the descendants of the children of the Sun, the creator of fire and disease and protective of the “inner Earth.”

The brave Macuxi Indians of the Amazon

Oral legends tell of an entry on Earth. Until 1907, the Macuxies entered a sort of cavern, and traveled 13 to 15 days until they reached the interior. It is there, “on the other side of the world, in the inner Earth” where giant creatures that are about 3-4 meters high living.

According to Macuxies were given the task of monitoring to outside the entrance and prevent outsiders from entering the “hollow Earth.”

Legends say Macuxi people entering the mysterious cave for three days, only giants descend stairs, measuring about 80 centimeters each step. After the third day, they leave behind their torches, and continue their journey “inside” Earth illuminated by the lights that were already present in the caves. Giant lanterns, the size of a watermelon, shining like the sun. After 4-5 days of travel, those inside the cave lose weight and body mass, allowing them to move much faster.

The legends of the Macuxi say after 5 days inside the caverns, they would go by huge caverns whose roofs could not be seen, and one of the chambers of the cave system, there are four objects “like the sun”, which are impossible to watch, whose purpose is unknown to the Macuxi village.

Within the Earth, there are places where trees are able to grow food. The Macuxi say cajúes fruits like, oak, mangos, bananas and some smaller plants are in 6-7 days into their journey. The farther the Macuxi people moved into the Earth, larger areas of vegetation observed. But not all areas are green and prosperous color. The Macuxi people say that some places are extremely dangerous and should be avoided, as those with boiling stone and streams “azoge.”

Macuxi Oral traditions continue and say that after going through these giant cameras, having spent half the trip have to move carefully as the mysterious “air” can cause people to “fly or float” around. Continuing their journey, they reach a place within the Earth, where the Giants lived. There, the Macuxi explorers ate food giants such as apples the size of human heads, grapes the size of a human fist, and delicious and giant fish were captured by the giants and the Macuxi given as gifts.
