Sinarka (Russian: Синарка) is a stratovolcano located at the northern end of Shiashkotan Island, Kuril Islands, Russia. Most eruptions occurred during the 17th and 18th centuries, although there has been some recent activity,[when?] mostly steam and thermal activity. A large eruption would not affect large populations; only three people are located within 10 km.[1] 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 540 feet (160 m) of prominence.[2]
