Jakarta, CNBC Indonesia – An extraordinary phenomenon had occurred on Earth. The Earth’s core had stopped and allegedly reversed direction. The impact of this phenomenon is also felt by mankind.

The study, published in the journal Nature Geoscience, found an oddity in the Earth’s core. According to China’s Peking University Team, the findings show rotational changes on a decadel scale.

They also added that their findings could help understand what happened at the bottom of the Earth and ultimately affected the surface, quoted Popsci, Tuesday (13/6/2023).

The Earth’s core consists of two layers, namely the liquid and solid outer core. In the solid section, it is made of iron that actually rotates.

Seismologists Yi Yang and Xiaodong Song, two of the study’s authors, observed Earth’s seismic waves. They analyzed differences in waveforms and travel times when earthquakes traveled along the same path since the 1960s.

The earthquakes investigated occurred from 1995 to 2021.

Prior to 2009, it turned out that the Earth’s core rotated slightly faster than the surface and parts of the mantle. But then slowed down and stopped around the year.

The research team also believes the results could be linked to a seven-decade reversal of core rotation. This was in the early 1970s, they said.

In addition, the team also explained that this variation is related to small changes in geophysical observations on the surface. For example, the length of the day or changes in the magnetic field.

Volatility in the rotation of the Earth’s core, influences the variation in the time it takes the Earth to rotate on its axis. Finally, humans on the surface of the Earth feel the length of the day varies.

The study authors concluded that fluctuations in the rotation of the core along with a number of periodic changes indicate interactions between the different layers of the Earth.
