Sintesi geologica

Hunter Island, the SE-most volcano of the New Hebrides arc, is a 1-km-wide island consisting of a composite andesitic-to-dacitic cone topped by explosion craters and a lava dome. The island was named after the English trading ship that reported sighting it in 1798. A 100-m-deep, steep-sided crater occupies the NW part of the island, which contrasts with the southern cone, whose summit is filled by a lava dome. Several poorly documented eruptions have been noted since the 19th century. Large streams of lava were reported to be pouring from two craters on the eastern side of the island in 1895; the latest eruption apparently took place from the northern tip. Fumarolic and solfataric areas are located at the northern tip of the island and the NE and SE coasts.

Riassunto in inglese

Matthew Island and Hunter Island are two uninhabited volcanic islands in the South Pacific, 300 kilometres (190 mi) east of New Caledonia and south-east of Vanuatu. The pair, which lie 70 km (43 mi) apart, are claimed by Vanuatu as part of Tafea Province, and considered by the people of Aneityum part of their custom ownership, but also claimed by France as part of New Caledonia.
