'Wind' from Earth's middle layer blows through secretpassage beneath Panama

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. 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 at Woods Hole Oceanographic Institution in Massachusetts.

To learn more, the researchers delved into the geochemistry of the region, collecting volcanic rock samples as well as gas and fluid samples from hot springs. They were interested in looking at ratios of molecular isotopes, which are variations of the same atoms with different numbers of neutrons in their nuclei. In this case, the researchers were particularly focused on isotopes of helium and lead. 

"We found that in particular places of Central America, namely western Panama and behind the volcanic arc in Costa Rica, we have some exotic signatures [of geochemistry] that really resemble what you have in the Galápagos Islands," Bekaert said.

Galapagos looks like a mystical place to me… also maybe the gates to Chromatica are hidden beneath Panama as well :trollga:

So its a pressure release valve?

Geology is not my strongest asset so I legit can't tell. :bradley:

I hope it is not toxic fumes.

this. I was gonna make an earth farting joke after this was posted but I genuinely can't tell if it applies.
