Key Points

The aim is to investigate the origins and recurrence patterns of the South Atlantic Anomaly using paleointensity data over 2000 years.
Analysis of geological samples from central South America to obtain paleointensity measurements.
Reconstruction of the Earth's magnetic field variations over the last 2000 years.
Comparison of results with previous geomagnetic records to detect anomalies.
Identification of significant fluctuations in paleointensity correlating with the timing of the South Atlantic Anomaly's occurrences.
Data suggest a cyclical pattern in the anomaly, potentially influencing geomagnetic behavior in the region.
Findings support the hypothesis of a long-term dynamic in the Earth's magnetic field impacting the South Atlantic Anomaly.
