Earth's Core Slowed Down – Scientists Explain Whether It's Dangerous for People

Scientists have confirmed that Earth's inner core has slowed its rotation and changed its direction of movement. A study in Nature, based on seismic data since 1964, revealed a 70-year cycle of oscillations. Seismologist John Vidale stated that this is not dangerous for humans.

Earth's inner core, located at a depth of about 5,180 kilometers, has slowed its rotation and changed its direction of movement. This conclusion was reached by scientists who published a study in the journal Nature. They analyzed seismic waves from earthquakes dating back to 1964, as well as data from Soviet nuclear tests in 1971-1974. It turned out that the core's rotation follows a seventy-year cycle, in which phases of deceleration alternate with acceleration. According to calculations, in ten years the rotation will begin to accelerate again. Seismologist John Vidale from the University of Southern California stated that this process does not pose a threat to humans. The exact causes of the cyclic changes remain a mystery to science.
