Abstract
An empirical correlation between spatial variations in the geomagnetic field and the motions of the lithospheric plates was identified by Goodacre in 1987. In this paper a further correlation between the geomagnetic field and the lithospheric plates is suggested. It derives from the distribution of virtual geomagnetic poles calculated for the nodes of a world-wide grid on the basis of the coefficients of the 1980 International Geomagnetic Reference Field (IGRF). It is assumed that the distance between two virtual geomagnetic poles corresponding to two points lying on the same circle of latitude depends on the rate of the westward drift in the given place. This assumption is examined by means of a time series of geomagnetic field values from magnetic observatories. The results show that the zones with the minimum distances of corresponding virtual poles occur in the vicinity of zones of subduction or rifts in many cases.
