Earth Inner Core Rotation

The new research provides evidence that the inner core began to decrease its speed around 2010, moving slower than the Earth's surface.

A new study has provided "unambiguous evidence" that the Earth's inner core began to slow down its rotation since 2010, compared to the planet's surface.

New research published in the journal Nature Geoscience analysed seismic waves from repeating earthquakes over the last six decades.

Contradicting a previously accepted theory, scientists have concluded that the inner core of the Earth oscillates and results in variations in the length of the day. It was earlier believed that the inner core, which is the hottest part of the Earth, rotates at a speed faster than the planet’s surface.
