Photo Gallery

Savai'i, the largest and highest of the Samoan islands, fills this NASA Landsat image (with north to the top). The 75-km-long island consists of a massive basaltic shield volcano constructed along a WNW-ESE-trending rift zone that splits into two rifts on the east side of the island. The broad crest of Savai'i is dotted with numerous cinder cones and lava cones, some of which were the source of historical eruptions that produced lava flows that reached the sea.

The oval-shaped, 75-km-long island of Savai'i, the largest and highest of the Samoan islands, consists of a massive basaltic low-angle shield volcano. Numerous cinder cones and lava cones dot the broad crest of Savai'i, which has a low-angle, dome-like profile and reaches an elevation of 1858 m. The fresh lava flows in the foreground were erupted during the most recent eruption of the volcano in 1905.

A major eruption of Savai'i took place from August 4 to November, 1905. Voluminous lava flows from the Matavanu vent on the north flank flowed 12 km to sea, destroying several villages and many fields. This image shows a pressure ridge on the lava flow, with the north coast in the background.
