The circular, 5.5-km-wide island of Baluan in the Admiralty Islands is formed by a Pleistocene stratovolcano with a large summit crater and several flank vents. Some of these might be of Holocene age (Johnson, 1990 pers. comm.). In contrast to its neighboring islands to the north, Baluan has erupted basaltic rather than rhyolitic rocks. Sabroma, the elliptical summit crater, has a maximum width of about 1 km. The arcuate rim of the Batapona pyroclastic cone is prominent at the north edge of the island. Several small islands consisting of cone remnants are located within a kilometer of the north coast. Warm springs occur along the coast. An unsubstantiated description of a submarine eruption near the island in 1931 has been assigned to the Tuluman volcano of the St. Andrew Strait complex, located 9 km NNE of Baluan..
