[Rockhounds] USC Researchers Prove Earth’s Core Is Losing Speed

[Kreigh Tomaszewski]

Scientists at USC have proven that the Earth’s inner core is backtracking —
slowing down — in relation to the planet’s surface, as shown in new
research published on June 12 in the journal *Nature*.

The scientific community has long debated the movement of the inner core,
with some studies suggesting it rotates faster than the Earth’s surface.
However, recent research from USC conclusively shows that starting around
2010, the inner core has slowed down, now moving at a pace slower than that
of the planet’s surface.

“When I first saw the seismograms that hinted at this change, I was
stumped,” said John Vidale, Dean’s Professor of Earth Sciences at the USC
Dornsife College of Letters, Arts and Sciences. “But when we found two
dozen more observations signaling the same pattern, the result was
inescapable. The inner core had slowed down for the first time in many
decades. Other scientists have recently argued for similar and different
models, but our latest study provides the most convincing resolution.”
