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 They were both created by the same hot spot, magma rising from the mantle, under the Pacific plate.They are no longer active because the Pacific plate has moved west.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 are associated with three types of tectonic structures: convergent plate boundaries, divergent plate boundaries and hot spots. California has all three. The SAF is a transform plate boundary (strike slip fault) and so is not accompanied by volcanic activity. The Gorda Plate is subducting under the North American Plate north of Cape Mendocino and is the cause of the state's two active volcanoes, Mt Shasta and Mt. Lassen.
