Earth's inner core rotation slowing since 2010 - USC study

India Today — June 14, 2024, 07:00 AM UTC

Summary: The Earth's inner core has been slowing down since around 2010, as discovered by USC scientists analyzing seismic data. This slowdown is influenced by the liquid outer core's churning and gravitational forces from the mantle. The inner core's movement affects Earth's magnetic field and day length. Further research aims to understand this phenomenon's implications on Earth's interior dynamics. This groundbreaking finding was published in Nature.
