Hotspot highway
The hotspot highway is a term coined in 2010 by Boston University professor Matthew G. Jackson to describe the area of the South Pacific where the tracks of the Samoa, Macdonald, Rurutu, and Rarotonga hotspots all cross paths with one another.[1]
Geochemical evidence from several volcanoes in the Samoan region is consistent with the argument that older hotspot tracks are present in the Samoan archipelago. Rose Atoll, , and seamounts plot the Samoan track and are not geochemically consistent with the other Samoan islands, suggesting that they were not created by the Samoan hotspot.[1]
