Antipodal hotspot pairs on the Earth

Abstract

The results of statistical analyses performed on three published hotspot distributions suggest that significantly more hotspots occur as nearly antipodal pairs than is anticipated from a random distribution, or from their association with geoid highs and divergent plate margins. Two possible mechanisms that might create such a distribution include: 1) symmetry in the generation of mantle plumes, and 2) melting related to antipodal focusing of sesimic energy from large-body impacts. -from Authors
