07/1991 (BGVN 16:07) Fumarolic activity

"During our survey, no change in activity at the major geothermal areas (Frenchman's Solfataras and Hell's Gate) was noted, with respect to descriptions by Aubert de la Rue (1937) and Hochstein (1980). Slightly superheated fumaroles (with sulfur deposits), hot springs, and boiling ponds up to 3 m in diameter occurred over a 300-m strip along the Sulfur River (E flank) between 300 to 400 m elevation. The temperature of the Sulfur River at Hell's Gate remained stable at 50°C.

"Soretimeat . . . is a composite volcano built on an ancient Pleistocene edifice. Ash emissions reported in 1860 and 1965-66 are most likely to have been from hydrothermal explosions (Ash and others, 1980)." ["Flames" were observed during an apparent eruption in 1865 (Atkin, 1868).]

Suretamatai volcano forms much of Vanua Lava Island, one of the largest of Vanuatu's Banks Islands. The younger lavas of 921-m-high Suretamatai (also known as Soritimeat) volcano 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. Historical activity, beginning during the 19th century, has been restricted to moderate explosive eruptions.

The southern two-thirds of Vanua Lava Island is seen in this NASA Space Shuttle 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 cloud banks at the top of the image. The Pleistocene Ngere Kwon volcano forms the peninsula at the bottom of the image, and small offshore islands at the right are uplifted reef limestones. Historical activity, beginning during the 19th century, has been restricted to moderate explosive eruptions.
