Earth's Inner Core: Shape Change and Magnetic Field

A recent scientific study suggests Earth's inner core may have undergone shape changes within the last two decades. This conclusion stems from analysing seismic waves from repeating earthquakes between 1991 and 2023. These potential deformations, occurring at the boundary between the inner and outer core, might be linked to the core's rotation and the planet's magnetic field. Researchers suggest that gravitational pulls and the liquid flow of the outer core could contribute to this shifting structure. Understanding these core dynamics is crucial, as they affect the magnetic field that protects Earth from solar radiation. While these findings probably will not affect day to day life, they offer new avenues for understanding the dynamics within our planet.
