Nemo Peak is a caldera with at least three historic eruptions: 1710, 1906, and 1938. The historic eruptions have been moderate intensity and explosive.
This photograph is looking to the southeast across the islands of Onekotan, Kharimkotan, and Shiashkotan (left to right, respectively). The islands of Makanrushi, Ekarma, and Chirinkotan are behind (west of) the main volcanic arc. Tao-Rusyr caldera and crater lake can clearly be seen on Onekotan. Fuss Peak forms the north (left) side of this island. Ekarma Island and volcano is northwest of Sinarka. Ekarma last erupted in 1980. Makanrushi Island (island closest to the bottom of the photo) is probably volcanic in origin but is not listed as an active volcano.
