Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Koniuji

A steep, arcuate cliff drops nearly 300 m to the coast on the western side of Koniuji Island. This very small, 1 x 1.5 km wide island, located between Atka Island and Kasatochi volcano, is the emergent top of a mostly submarine volcano. A NE-trending fault cuts the SE side of the island (right). Despite its apparently dissected condition, Holocene lava flows and domes have been dated. Reports of eruptive activity may be erroneous and are considered to refer to eruptions of the relatively undissected Kasatochi volcano to the west. Photo by E. Bailey, 1982 (U.S. Fish and Wildlife Service).
