Geologic Background. Isolated Matthew Island is composed of two low andesitic-to-dacitic cones separated by a narrow isthmus. Matthew Island was discovered in 1788 by a ship captain, who named the island after the owner of his vessel. Only the triangular eastern portion of the small, 0.6 x 1.2 km wide island was present prior to the 1940s, when construction of the larger western segment began; it consists primarily of lava flows. The 177-m-high western cone contains a crater that is breached to the NW and is filled by a lava flow whose terminus forms the NW coast.
