In 2009-2010, the rotation of the Earth's inner core completely stopped. After such events, the inner core is expected to resume rotation, presumably in the same direction as the Earth itself.

Based on their analysis of seismic waves caused by similar earthquakes dating back to the 1960s, Yang and Song said they found that the inner core’s rotation seems to have “paused” between ...

Earth’s solid metal core may no longer be spinning relative to the vast mass of the surrounding planet thanks to what appears to be a recent slowdown, according to the results of a new study.

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many ...

A team of researchers from China believe the Earth’s inner core has reversed its rotation after they analyzed earthquake-driven seismic waves as they pass through the Earth. In a study published ...

(NEXSTAR) – Deep in the center of the Earth is the inner core, which spans roughly 746 miles and is composed of primarily pure, solid iron, NASA explains. Though we’ve long believed – and ...
