Easter hotspot
From Wikipedia, the free encyclopedia
The Easter hotspot is marked 7 on map.
The Easter hotspot is a volcanic hotspot located in the southeastern Pacific Ocean. The hotspot created the Sala y Gómez Ridge which includes Easter Island and the Pukao Seamount which is at the ridge's young western edge.
The hotspot may also be responsible for the formation of the Tuamotu Archipelago, Line Islands, and the chain of seamounts lying in between.[1]
Opponents of the hotspot theory instead attribute Easter hotspot to the middle part of the Easter Fracture Zone.[citation needed]
