Is the Earth showing signs of turning upside down from the inside?

A mysterious thing in the Earth's outer core has disappeared from its old position after only 20 years, possibly related to the fact that the Earth's North Pole is drifting from Canada to Siberia - Russia.

The study, led by geologist Ying Zhou from Virginia Polytechnic University in the US, looked at geological waves propagating from two different earthquakes, at similar locations but 21 years apart.

There are two earthquakes near the Kermadic Islands in the South Pacific Ocean, the first in May 1997; Second match in September 2018.

The texture of the Earth's interior

The results revealed significant changes in the Earth's outer core, a layer of liquid iron and mixed nickel, located between the mantle (the rock beneath the crust) and the Earth's inner core. The outer core is what directly affects our planet's magnetic field, which creates a powerful magnetosphere like an armor that protects life from harmful elements from the universe.

"Something has changed in the path of that wave, so it can go faster now," Dr. Zhou was quoted as saying by Science Alert.

The material in the path of the seismic waves is a new and lighter material, which can contain many elements such as hydrogen, carbon and oxygen, which has been released in the outer core since 1997.

This change in material suggests a disturbance in the core, causing materials in different locations to migrate to new regions.

This is thought by the team to be directly connected to the phenomenon that the Earth's north pole - the true magnetic north pole - is no longer located in the place called "North Pole" on the map but is wandering in the Arctic Ocean. , coming to the shores of Siberia - Russia.

The shift of the North pole is thought to be a foreshadowing of the phenomenon of "Earth overturn", which is the reverse of the magnetic pole, causing the South pole to jump to the current position of the North Pole while the North pole actually "drifts". down to the center of the Antarctic continent.

Magnetic pole reversals won't cause the apocalypse, but can damage human radio and telecommunications systems and push us into a period of weaker magnetic fields and more extreme climates due to exposure to solar radiation. more intense radiation from the Sun.

Dr. Zhou's team plans to continue to monitor the transformation of Earth's outer core thanks to a global network of 152 seismic stations, to better understand the workings of this mysterious and deep world. .
