Magnetic reversal trajectories compared to position of magnetic Pacific slab and reversal trade

Map of the world centred on the Pacific, with red dots showing position of magnetic pole as it migrated between geographic poles during multiple field reversals. In the western Pacific, the red dots overlap with the inferred position of subducted and magnetic oceanic lithosphere, shown in blue.

Blue region: position of subducted lithosphere in Western Pacific at mantle depths of 500km. Red dots: ‘virtual geomagnetic poles’ from multiple reversals, including the last one. Source: Kupenko et al., 2019.
