The massive, basaltic shield volcano forming 75-km-long Upolu Island in Samoa is seen in this Space Shuttle view (with north to the upper left). The youngest lava flows, erupted after a lengthy period of erosion, originated from vents near the crest of the island and may be only a few hundred to a few thousand years old. Apolima Island, the small circular island west of reef-bounded Manono Island off the western tip of Upolu (lower right), is a Holocene tuff cone too young to be fringed by a coral reef.

The forested cinder cone of Tafua Upolu rises near the western tip of 75-km-long Upolu Island in Samoa. The massive shield volcano is elongated in an E-W direction and was constructed during two periods of extensive eruptions during the Pliocene and Pleistocene. Following a lengthy period of erosion, the latest lava flows, at least three of which were estimated to be as young as a few hundred to a few thousand years old, were erupted from vents near the crest of the island at its center and western side.
