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 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.
Earth’s inner core changing shape? Scientists reveal it may have 'deformed by over 100 meters'
New research suggests that Earth's inner core, long believed to be stable, may be undergoing structural changes, including a possible shift in shape, shedding light on the mysteries beneath the planet
Forces deep underground seem to be deforming Earth's inner core
Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades
Scientists discover yet another change to Earth’s inner core: Its shape
Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills and valleys.
Earth's inner core is mysteriously changing its shape and affecting life in a strange way, say scientists
Scientists suggest Earth's inner core may have changed shape over the past 20 years, potentially affecting the planet's magnetic field, based on seismic wave analysis.
Strange doughnut-shaped structure found inside Earth’s core – We don’t know what it is
We are unsure of the nature of the strange doughnut-shaped structure discovered inside the Earth's core. We thought Earth had only four layers.
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
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
The planet’s inner core was previously thought of as a hard, solid sphere. But a new study has found that its edges are softer than realized and actually changing shape.
Two buried ‘supercontinents’ hiding inside Earth could be much older than previously thought
Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...
Recordings from South Sandwich Islands reveal the earth's core is changing
Research reveals structural changes in the inner core's surface, indicated by differences in seismic wave pairs.

The Earth’s Mantle is Far More Dynamic and Chaotic Than We Thought
Many people envision Earth’s structure as a tidy ... scientists can map anomalies in the mantle, like faster wave speeds indicating colder, denser materials, or slower speeds suggesting hotter ...
