Per esempio, la catena di vulcani sottomarini Hawaiani sembra segua questa regola:
Each successive volcano spends less time actively attached to the plume.
Se l'hot-spot scende verso sud, questa regola ptrebbe essere in accordo con la rotazione differenziale (maggior velocità all'equatore)
The oldest volcano in the chain, Meiji Seamount, perched on the edge of the Aleutian Trench, formed 85 million years ago.[48] At its current velocity, the seamount will be destroyed within a few million years, as the Pacific Plate slides under the Eurasian Plate. It is unknown whether the seamount chain has been subducting under the Eurasian Plate, and whether the hotspot is older than Meiji Seamount, as any older semounts have since been destroyed by the plate margin. It is also possible that a collision near the Aleutian Trench had changed the velocity of the Pacific Plate, explaining the hotspot chain's bend; the relationship between these features is still being investigated.
Questa seconda ipotesi significa che la catena si è intoppata a nord dove subduce e facendo perno ha deviato (in corrispondenza di una trascorrenza) la placca e piegato in dentro il bordo continentale?
