The Tana volcanic complex forming the eastern half of the dumbbell-shaped Chuginadak Island, opposite the dramatic conical Cleveland stratovolcano, is composed of two prominent E-W-trending volcanoes. The complex shows evidence of glacial erosion, but the observation on satellite imagery of highly irregular coastlines forming peninsulas west of Applegate Cove on the NW side of the complex and Concord Point on the south side imply lava flows of mid- to late-Holocene age (Nye 2007, pers. comm.). Prominent lava flow levees are visible near Concord Point, where a low-silica rhyolite sample was obtained. The undissected cone and youthful crater forming the western summit also imply a post-glacial age, and youthful cinder cones also lie east of the isthmus between Cleveland and Tana volcanoes.
The Global Volcanism Program is not aware of any Holocene eruptions from Tana. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Tana page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
The Global Volcanism Program has no synonyms or subfeatures listed for Tana.
|The Tana volcanic complex in the center of this NASA Shuttle image forms the eastern half of the dumbbell-shaped Chuginadak Island, opposite the slopes of Cleveland stratovolcano, visible at the upper left. The highly irregular coastlines forming peninsulas west of Applegate Cove on the NW side of the complex and Concord Point on the south side imply lava flows of mid- to late-Holocene age, and prominent lava flow levees are visible near Concord Point. An undissected cone and youthful crater forms the western summit.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
