The discovery was made thanks to seismic images. These “structures” are located at the “primary-mantle boundary”, more than 2,900 kilometers underground, and would be five times higher than Everest.

The area between Earth’s core and mantle is full of mysteries.

One of them was revealed by the magazine on Wednesday, April 5 science. Specifically, the researchers were able to discover “structures“A height equivalent to five times Mount Everest, thanks to seismic imaging. They were able to obtain these results through a study”Primary mantle boundaryMore than 2,900 kilometers underground.

use of seismic waves

But to achieve this, scientists did not tunnel to the center of the Earth: the core is too deep. Then they used seismic waves generated by earthquakes. When passing through different layers of our planet, the speed of these waves increases and decreases, which makes it possible to detect the mentioned “structures”, according to reports Huffpost.

Then the team of scientists led by geophysicist Samantha Hansen, who teaches at the University of Alabama, discovered, “The ULVZ is extensive and variable along the core-mantle boundary“, identified thanks to the seismic information collected in Antarctica. In addition to the new data useful for understanding the structure of the Earth’s layers, the mysteries surrounding the geophysical activity of the Earth’s core can be solved through this discovery.
