After analyzing the movement of seismic waves and recent changes, a group of Chinese researchers confirmed that the Earth’s inner core has changed its rotation axis.

The researchers pointed out that changing the rotation of the Earth’s inner core would shorten the length of days by a fraction of a second throughout the year, in a study published in the scientific journal Nature Geoscience on Monday.

They also pointed out that this will also contribute to the effect, slightly, on the Earth’s magnetic field, according to what was reported by the “Wall Street Journal”.

Earthquakes and earthquakes

In turn, the study’s assistant researcher and expert in seismology from the University of Peking, Xiadong Song, said that in theory, this matter lasted for a long time, but there are indications that it began only decades ago.

Song noted that the rotation of the Earth’s inner core is caused by the magnetic field generated by the outer liquid layer, and studying its rotation movement can help scientists understand how the different layers of the Earth interact with each other.

He also studied the seismic waves resulting from earthquakes and compared them to similar tremors in the 1960s, and discovered that the rotation of the Earth’s inner core stopped between 2009 and 2020, and they suggested that it had reversed the direction of its rotation, saying: “We have these earthquakes that occur in the same locations … we were We subject the Earth to a tomogram.

second opinion

However, a professor from the University of Southern California, John Vidal, who did not participate in the new study, has another opinion, as he found that there may be another analysis of the data presented by the researchers, and that the changes that the researchers observed are credible, but the exact reason for what is actually happening is not clear.

He emphasized that the researchers’ analysis is very good and their theory mentioned in the study is good compared to what is currently available, but there are other ideas that may compete with it, he said.

Vidal stated that other scientists believe that the changes in the rotation of the Earth’s inner core are shorter than the seventy years that the study focused on, while theories developed by other scientists indicate that the inner core stopped moving between 2001 and 2003 or that its rotation movement was never reversed. Her movement style changed.

It is noteworthy that the inner core of the Earth consists of iron and nickel, and it is separated from the solid part of the Earth by a liquid outer layer, which helps to change its movement differently from the entire planet.
