Sinarka

Sinarka (; ; Kurodake) 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.
