The shape of the domestic nucleus of the Earth is changing, according to scientific research

New scientific research has shown that the internal layer, the internal nucleus, is changing, and for that conclusion the latest earthquakes have been studied.

According to the CNN chain report, the research team noticed that the internal nucleus once rotated faster than the land itself. They found that since 2010 he slowed down and is now turning back, in relation to the rest of the planet.

The new study was published in the scientific journal Nature Geoscience. It has taken into account the earthquakes between 1991 and 2023.

John Vidale is the co -author of the investigation. “We can compare the signals that we see when the internal nucleus returns to the same position it had at some other time and see if there are differences that cannot be explained by rotation”Said Professor of the University of Southern California.

Today it is impossible to study the Earth’s core directly. It is estimated that it is formed of nickel and iron, and has a radius of 1,221 kilometers, reaches 5,400 degrees Celsius and the pressure is three million times greater than the atmosphere.

The only way to study their behavior is through seismic waves. “It is almost science fiction to visualize what is happening on the surface of the internal nucleus”Said Vidale.

The scientists analyzed 168 waves paired with earthquakes in 42 locations. It indicates the research that is likely that the external nucleus is displacing the internal core, although “it is difficult to know if we are observing an anomalous or normal location.”
