Details for: Nemo Peak
Steep-sided Nemo Peak, seen here from the south, is the northernmost of two large volcanoes forming Onekotan Island. The 1018-m-high compound central cone of Nemo Peak formed in four stages beginning in the early Holocene. Construction of the cone within the youngest of three large calderas has left a crescent-shaped lake at the NE end of this 5-km-wide caldera. The final activity built a lava dome in the 350-m-wide summit crater. Historical eruptions of Nemo Peak date back to the early-18th century. Photo by Yoshihiro Ishizuka, 2000 (Hokkaido University).
