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 They were both created by the same hot spot, magma rising from the mantle, under the Pacific plate.They are no longer active because the Pacific plate has moved west.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.

Volcanoes can also occur at hot spots, such as at the areas of the Hawaiian islands and Yellowstone in America. This type of volcano forms when magma from the mantle rises to Earth's surface through a certain spot in the middle of the plate (i.e., the Pacific Plate for the Hawaiian Islands).olcanoes usually occur where there are collision of the tectonic plates. There are 52 tectonic plates which either pull (gap and crack) or push (volcano). Volcanoes are actually tectonic plates which have magmas beneath their outer surface.
