The Tana volcanic complex is the eastern part of Chuginadak Island, shown in this 23 August 2020 Sentinel-2 satellite image (N is at the top; this image is approximately 17 km across). The summit area is a nearly E-W alignment of volcanic centers, with the lake-filled summit crater on the western end. From the western rim of that crater is the E-W Tana fissure, and from there down into the Chuginadak isthmus are additional younger fissures and scoria cones. Cleveland volcano forms the western part of the island.
