Nemo Peak Volcano

Nemo Peak volcano on the northern end of Onekotan Island in the northern Kurile Islands is a complex of 3 overlapping calderas and a young central cone, Nemo Peak, which has been active for about 9,500 years.
It has a 350 m wide summit crater filled by a lava dome with a 150 m wide crater itself. Nemo Peak has been historically active and observations date back to the early 18th century.

Background
The pre-glacial edifice of Nemo Peak volcano is cut by 2 nested nested calderas, the larger measuring 10 km in diameter and reaching the northern coast of the island.A third, younger caldera formed about 25,000 years ago and destroyed a summit cone that had grown above the older calderas.
Present-day Nemo Peak is composed of two coalescing andesitic cones that were constructed at the SW side of the youngest caldera beginning in the early Holocene about 9500 years ago.
As a result of the formation of the cone, the Chernoe Lake at the NE end of the caldera got its crescent-shape. Lava flows from Nemo Peak form the broad SW shoreline of the lake.
The recent activity is the formation of the summit lava dome and includes the historic activity of the volcano.
