Scientists have discovered that Earth's inner core is changing shape, overturning the belief that it was solid and unchanging. This finding, derived from seismological analyses of seismic waves traveling across the globe, indicates that the inner core is deforming. This dynamic change raises questions regarding its implications on Earth's 24-hour day length and its magnetic field. Researchers emphasize that this discovery sheds new light on the Earth's interior dynamics after extensive investigation into seismic signals from earthquake activity.
After decades of research and debates, we are coming to an ever-clearer picture of the changing inner core.
For the first time we're seeing that it's deforming.
