(ORDO NEWS) — Scientists from the University of Liverpool conducted another study, the results of which showed that the magnetic field in the South Atlantic region behaved extremely strange about 8-11 million years ago.
This indicates that this anomaly recurs regularly at regular intervals and is not a sign that a change in the Earth’s magnetic poles will necessarily occur.
The South Atlantic Anomaly is a part of our planet that does not have as strong a magnetic field as the rest of the surface, which is located in the same geographical latitude. The level of protection against cosmic radiation in this area is much lower.
The main manifestations of this can be seen in the frequent malfunctions of various technical devices that are on board space objects and satellites.
A new study led by Yael A. Engbers analyzed the paleomagnetic traces that have been preserved in igneous rocks. The rock samples were taken from Saint Helena, which is located near the occurrence of this anomaly.
Between 8 and 11 million years ago, 34 volcanic eruptions occurred. The rocks, after careful analysis, showed a high level of remanent magnetization. This suggests that during this period the direction of the magnetic field in this area often changed.
Exactly the same deviations are observed today. It is worth noting that some scientists still continue to believe that this anomaly indicates an imminent change of the planet’s poles, although the study clearly proved the recurrence of the event and its non-involvement in the change of poles.
The research carried out by experts and its results was published in the popular scientific journal Proceedings of the National Academy of Sciences.
