Sinarka

Sinarka is a stratovolcano which forms the northern end of Shiashkotan Island, Kuril Islands, Russia, and is the island’s highest point. Historical eruptions have occurred at Sinarka during 1825–1750, 1846, 1855, and the last and largest from 1872 to 1878. Recent activity is hydrothermal, from a solfatara field with more than 100 fumaroles and several hot, geyser-like springs which erupt water up to high.
A major eruption would not affect large populations; only three people are located within. The main structure of the volcano consists of the main peak, and two sub-peaks with a mellow ridge descending to the southwest. The larger sub-peak could be considered its own peak, due to its of prominence.
