The faster growth under Indonesia's Banda Sea hasn't left the core lopsided. Gravity evenly distributes the new growth—iron crystals that form as the molten iron cools—to maintain a spherical inner core that grows in radius by an average of 1 millimeter per year.
But the enhanced growth on one side suggests that something in Earth's outer core or mantle under Indonesia is removing heat from the inner core at a faster rate than on the opposite side, under Brazil. Quicker cooling on one side would accelerate iron crystallization and inner core growth on that side.
This has implications for Earth's magnetic field and its history, because convection in the outer core driven by release of heat from the inner core is what today drives the dynamo that generates the magnetic field that protects us from dangerous particles from the sun.
Asymmetric growth of the inner core explains a three-decade-old mystery—that the crystallized iron in the core seems to be preferentially aligned along the rotation axis of the earth, more so in the west than in the east, whereas one would expect the crystals to be randomly oriented.
Evidence for this alignment comes from measurements of the travel time of seismic waves from earthquakes through the inner core. Seismic waves travel faster in the direction of the north-south rotation axis than along the equator, an asymmetry that geologists attribute to iron crystals—which are asymmetric—having their long axes preferentially aligned along Earth's axis.

Just like bowling balls.
The giant egg that is Earth’s core is getting ready to hatch ...
Could explain why the earth is wobbling as it rotates on its axis changing the angle of tilt
Clearly, Trump’s fault!
There must be a mistake somewhere, climate change was not mentioned. Of course, things such as core changes could not possibly affect the climate, it must be the other way around.
Because Trump.
Nor was the increasing rate of the drift of the magnetic poles alluded to, and that is likely a related event.
More “Science” that needs to be ignored.
And yet people think we can project world climate patters 20 or 50 years out. We have no clue how an imbalanced earth’s molten core and subsequent impact on magnetism influences world climate. Now add in a thousand other variables.
Let me guess. You think the Earth is flat.
That is awesome.

Must be why half the world is insane.
We’re going to wobble off to new worlds!

I had to look that one up.
That’s us, only it’s God watching over us, so who knows what he’ll do next heh.
No, I don’t.
This particular “research”, based on models, inferences, and speculation, smells just like their climate “science”. In 20 years it will be in the error column, along with most of the other predictions of “what’s gunna happen” made by “Scientists”.
Are we supposed to be concerned about the (so called) lopsided iron crystal formation in the Earth’s interior? Is there something to be done about it? No. Sound familiar? Next come the doomsday predictions unless we stop eating beef.
Nonsense! They won’t try to make us stop trying to eat beef, it’ll be all real meat!
I for one can’t wait. I grow weary of their constant games and I just want to see them push us to new levels.
