Earth, inner core

Earth’s inner core is deforming—here’s what we know
In a nutshell Scientists have discovered that Earth’s inner core isn’t just changing its rotation speed – it’s actually deforming at its surface. This is the first time such structural changes have been observed on human timescales.
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
Earth’s Core Is Changing Shape
A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing hidden dynamics deep within Earth.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.
Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges
