The Global Volcanism Program is not aware of any Holocene eruptions from Tutuila. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tutuila page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Photo Gallery


The elongated, 32-km-long island of Tutuila in the center of the Samoan Islands is seen in this Space Shuttle 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).

Rocky cliffs and offshore rocky island mark the rugged coastline of Tutuila Island. The elongated, extensively eroded Tutuila Island in the center of the Samoan Islands consists of five Pliocene-to-Pleistocene volcanoes constructed along two or three 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 cinder cones that produced fresh-looking pahoehoe lava flows.
