Geological Summary. 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.
