Geological 'secret passage' found beneath the Earth

Scientists have discovered a previously unknown opening situated 62 miles beneath the planet's surface.
Referred to as a geological 'secret passage', this mysterious opening in the Earth's middle layer has been discovered beneath Panama - a country with surprisingly few active volcanoes.

The region lies on a line of volcanoes known as the Central American Volcanic Arc which is produced by a subduction zone where the Cocos tectonic plate is pushing oceanic crust underneath the continental crust of the North American, Caribbean and Panama tectonic plates.

Panama, which lies along this zone, should have a significant amount of volcanism, however for some reason it is relatively quiet - a mystery that has left scientists scratching their heads for years.

Now though, it seems that the newly discovered opening in the Cocos tectonic plate may be enabling material to flow through from one side to the other, sparing Panama from the brunt of the activity.
This subterranean 'flow' also appears to make it possible for mantle material to flow to Panama all the way from the Galapagos Islands - a process that has never been seen before.

"Different sources of geological material typically have different compositions, so we can track the contribution from different regions of the mantle," geochemist David Bekaert told Live Science.

"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 Galapagos Islands."

Understanding the exact nature of the processes involved however will require much further study.

It's always perplexing when you think that we are on a crust of rock floating on lava... If that tube jam, probably it will cause an impressive eruption !

Maybe this is a entrance from Jules Verne's book 'Journey to the Center of the Earth'`?

Evidence supporting hollow Earth theory.

Unlikely, since it's an enormous hole in red-hot solid rock that allows red-hot molten rock to pass through unimpeded.  So unless you're in a vessel that can protect your from temperatures of 1300°C and pressures ten times the Mariana Trench - unlikely. Also: either have someone on your crew who knows powerful magic, or take some sort of lava-proof nuclear torpedo missile system.  There aren't many Balrogs left in that part of the world but the few you find are really grumpy.
