Ringkasan geologi
Matthew Island is composed of two low andesitic-to-dacitic cones separated by a narrow isthmus. The Matthew name originates from an English mariner who sighted the island in 1788. Only the triangular eastern portion of the 0.6 x 1.2 km island was present prior to the 1940s, when construction of the larger western segment began; it consists primarily of lava flows. The western cone contains a crater that is breached to the NW and is filled by a lava flow whose terminus forms the NW coast.

Ringkasan InggrisMatthew 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.
