After the mystery of Bermuda Triangle scientists now know why Earth is moving due to weak magnetic field

The earth keeps moving as researchers finally understand the reason behind Earth’s weak magnetic field

In a study conducted by a research team at the University of Alberta, scientists try to demystify the facts about the Earth’s magnetic field just over the Pacific ocean. In May 2020, the European Space Agency (ESA) revealed in a study that the planet’s magnetic field is weakening in a few areas over South America and Africa. This unusual change in the planet’s geomagnetic field is termed as ‘South Atlantic Anomaly‘.

The research study conducted by a team of researchers at the University of Alberta helps solve the mystery behind the weird magnetic field of Earth over the Pacific. The study titled, “Weak magnetic field changes over the Pacific due to high conductance in the lowermost mantle” was published in Nature Geoscience this week.

Demystifying Earth’s changing magnetic field

After revealing the mystery behind the Bermuda triangle researchers are currently concentrating on this mystery. In the press release, the University of Alberta professor and lead author of the study, Mathieu Dumberry explained that the weakening might be due to the weaker core flow under the Pacific. Mr. Dumberry also mentioned that the topic has been a subject of curiosity since the 1930s when the fact about the weakening of the magnetic field was first established.

The new research study highlights that the core-mantle boundary region is quite heterogeneous. The conductance of the lowermost mantle is most probably not uniform around the globe. In fact, it seems to be higher in the Pacific as compared to any other area.
