Tahiti is comprised of two shield volcanos, Tahiti Nui and Tahiti Iti. They were both created by the same hot spot, magma rising from the mantle, under the Pacific plate.They are no longer active because the Pacific plate has moved west. Tahiti Nui is by far the most fascinating of the two shield volcanoes.The topography of the island is quite steep and does not show the gradual ascent for a normal shield volcano. The steepness is attributed to the many years of erosion from intense rainfall.mage borrowed from: http://www.welt-atlas.de/map_of_tahiti_3-190.

Hotspot volcanoes are considered to have a fundamentally different origin from island arc volcanoes. The latter form over subduction zones, at converging plate boundaries. When one oceanic plate meets another, the denser plate is forced downward into a deep ocean trench.s a result, they are less explosive than subduction zone volcanoes, in which water is trapped under the overriding plate. Where hotspots occur in continental regions, basaltic magma rises through the continental crust, which melts to form rhyolites. These rhyolites can form violent eruptions.
