Study finds: Earth's spinning inner core paused and reversed its direction
An interesting thing took place recently. A study found that Earth's spinning inner core paused and reversed its direction recently.
A new study has found something interesting and quite shocking actually. According to the report of the study the solid ball at the center of Earth's inner core appears to have stopped recently and may even be rotating in the opposite direction from previous decades.
Study finds: Earth's spinning inner core paused and reversed its direction
By analyzing data on seismic waves from earthquakes that have blasted through the Earth's inner core, a pair of scientists from Peking University in China have been examining the movements of the mysterious interiors of the planet. They can get a sense of what's going on in the Earth's inner layers, which are much deeper than any instruments or drills can reach, by observing changes in these waves. Recent studies they have done has showed some interesting results.
According to them, the data suggests that the inner core rotation paused because parts of the core that had previously shown clear signs of variation suddenly showed very little change around 2009. They also noticed significant changes in the waves around the beginning of the 1970s, which suggests that this pause was part of an oscillation that occurs once every seven decades or so, when the inner core slowly reverses direction.
