The research by scientists at the University of Southern California indicates that the solid inner core, which is suspended within the Earth's liquid outer core, gradually super-rotated faster than the material above it between 2003 and 2008, but then has slowed down over the following 15 years . Using analysis of seismic waves from earthquakes, the researchers created models of how the rotation of the Earth's core has varied between 1991 and 2023.
