Suretamatai

Gunung api kompleks · Vanuatu · 921 m

The southern two-thirds of Vanua Lava Island is seen in this NASA International Space Station image. Suretamatai volcano forms much of the island, with the most recent activity occurring in the northern part of the island near the area with small clouds at the top of the image. The Pleistocene Ngéré Kwon volcano forms the peninsula at the bottom of the image, and small offshore islands to the right are uplifted reef limestones. Activity that began during the 19th century has consisted of moderate explosive eruptions.

Ringkasan geologi

Suretamatai volcano (also known as Soritimeat) forms much of Vanua Lava Island, one of the largest of Vanuatu's Banks Islands. The younger lavas overlie a number of small older stratovolcanoes that form the island. In contrast to other large volcanoes of Vanuatu, the dominantly basaltic-to-andesitic Suretamatai does not contain a youthful summit caldera. A chain of small stratovolcanoes oriented along a NNE-SSW line gives the low-angle volcano an irregular profile. The youngest cone, near the northern end of the chain, is the largest and contains a lake of variable depth within its 900-m-wide, 100-m-deep summit crater. Activity reported during the 19th century consisted of moderate explosive eruptions.
