Photo Gallery

The elongated, 32-km-long island of Tutuila in the center of the Samoan Islands is seen in this International Space Station view (with north to the upper right). Five Pliocene-to-Pleistocene volcanoes were constructed along rift zones, and the Pago shield volcano in the center of the island was truncated by an eroded, 9-km-wide caldera that incorporates Pago Pago harbor (right-center). Following a lengthy period of erosion, the Leone tuff cones and cinder cones were erupted during the Holocene across the southernmost portion of the island (left-center).

Cliffs and an offshore island mark the rugged coastline of Tutuila Island. The elongated, extensively eroded Tutuila in the center of the Samoan Islands consists of five Pliocene-to-Pleistocene volcanoes constructed along rifts trending SSW-NNE. Following a lengthy period of erosion, submergence, and the construction of a barrier reef, the Leone volcanics were erupted during the Holocene along a 5-km-long N-S-trending fissure, forming a group of scoria cones that produced pahoehoe lava flows.

Tutuila Island is in the center of the Samoan Islands, shown in this 3 March 2019 Sentinel-2 satellite image (N is at the top; this image is approximately 44 km across). The extensively eroded island has multiple eruptive centers that have produced domes, cones, craters, and calderas.
