Left Bathymetry of Hawaii with Oahu Island and the Honolulu geomagnetic observatory (black diamond) in the centre. Red dots show the three sites where the scalar magnetic field was measured. Right Mantle 1-D conductivity profiles used in our 3-D model study. The blue curve stands for the global 1-D conductivity section (GLO) obtained from satellite magnetic data (Kuvshinov and Olsen 2006). The red curve depicts a regional 1-D conductivity section (PHS) beneath the Philippine Sea recovered from sea-bottom MT data (Baba et al. 2010)
