Numbers of L and R coconut palms counted around the circumferences of islands. A, Puerto Rico. B, Antigua. C, Hawaii. D, Maui. E, Tahiti/Moorea. F, Map of Pz, a scaled parameter representing the Z component of the anomalous geomagnetic field that arises from the distortion of electric current flowing in the ocean around Tahiti (Fig. 2F redrawn from Yamaguchi et al., 1992). Lines that bisect the islands in Figure 2, A to E, represent lines of symmetry connecting the estimated azimuths of zero asymmetry.
