The seismic structure beneath the South Pacific superswell has not been well explored in spite of its significance for mantle dynamics. The region is characterized by a topographic high of more than 680 m [ Adam and Bonneville , 2005]; a concentration of hot spot island chains (e.g., Society Cook‐Austral, Marquesas, and Pitcairn) whose volcanic rocks have isotopic characteristics suggesting deep mantle origin; and a broad, low‐velocity anomaly in the lower mantle that has been revealed by seismic tomography These observations suggest the presence of a large‐scale mantle flow from the bottom of the mantle beneath the region, which is called a ‘superplume’ [ McNutt , 1998[.
