Geophysicists have found the unexpected cause of a rapidly expanding fault separating a continent.
pig Live Sciencethis “foreign body” is a gravegiant super hot stone cluster mushroom shaperising from an area close to the Earth’s core. “Mushroom” It’s so big that it distorts the surface of the earth, in the future will tear Africa in two along a long path from the Red Sea to Mozambique.
The above results come from the research of geophysicist D. Sarah Stamps of Virginia Tech (USA) and her colleagues, through tests Great Rift Valley of East Africa in 12 years.

This valley has long been known as a giant rift in the Earth, where this giant continent will split into two in the future. What is the driving force behind this crack is still speculation.
In the new study, the authors found that in addition to the known perpendicular displacement to the east and west, there is also deformation parallel to the crack, move north. These surface movements are unusual and have never been observed elsewhere.
This anomaly led to a hidden structure inside – east “mushroom” giant And the dead – rising above the Earth’s mantle (the layer just below the planet’s crust).
“Mushroom” it’s a kind of giant cloak bundleformerly commonly associated with a variety of geological activities “little” more, like a volcano.
This new discovery shows that methane plumes also make an important contribution to the “Transfiguration” of the Earth’s continents, a process mainly caused by plate tectonics. Plate tectonics occurs when pieces of the earth’s crust move, sliding past each other and dragging continents and oceans above them.
