Crystals At The Center Of The Earth Results To Faster-Moving Seismic Waves In The East-West Part Of The World

For years, it has been observed that seismic waves travelling in the east-west part of the earth are faster than those in the other parts. And scientists may know the reason now.

According to them, the iron alloys located at the center of the earth appeared to have crystallized in a way that is easier to pass on the north-south axis than on the east-west. The study was led by Maurizio Mattesini, a geologist at the Universidad Complutense de Madrid. It was published on the journal Proceedings of the National Academy of Sciences.

“The structure of the atoms looks different in one direction than the other,” Norm Sleep, a geologist who was…
