An analysis of seismic waves from earthquakes that occurred between 1991 and 2023 near the South Sandwich Islands in the Southern Ocean showed that Earth’s inner core is not a perfectly uniform sphere but a structure with shifting regions, altering its topography over time.
Two Australian scientists discovered a ‘seismic abnormality’ in the Earth’s outer core — a “donut” of energy around the equator, where seismic waves move about 2% slower than in other core regions. Their study provides new clues about the dynamics of our planet’s magnetic field.
A new scientific study proves that the Earth’s rotation speed has been decreasing throughout the past decade, with data suggesting that the rotational speed of the inner core has gotten 2.5 times slower compared to the past decade.
Researchers from China have confirmed an 8.5-year Inner Core Wobble (ICW) in Earth’s polar motion and length-of-day variations, revealing a static tilt of about 0.17 degrees between the inner core and mantle, challenging long-standing assumptions about Earth’s internal dynamics.
According to a new study published in the journal Nature Geoscience, the inner core of the Earth may have stopped rotating faster than the rest of the planet around 2009 and then turned in an opposite direction.
Seismic waves are helping scientists to plumb the world’s deepest mystery: the planet’s inner core.Thanks to a novel application of earthquake-reading technology, a research team at the University of Illinois and colleagues at Nanjing University in China hav
Scientists believe they have achieved the first accurate estimate of how much faster Earth's core is rotating compared to the rest of the planet. University of Cambridge study has discovered that earlier estimates of one degree quicker each year were wrong. The
