Matthew Island is composed of two cones separated by a narrow isthmus. Only the triangular eastern portion of the small, 0.6 x 1.2 km wide island existed prior to the 1940s, after which eruptions began to build the larger western segment (part of which is seen in the photo). The western cone consists primarily of lava flows and contains a crater that is breached to the NW.
