Yantarni is a small andesitic stratovolcano located between Aniakchak caldera and Chiginadak volcanoes that was not discovered until 1979. A large breached crater on the NE side, which was formed by collapse of the summit about 2000-3500 years ago, contains a lava dome that marks the volcano's 1345 m high point. This eruption, which resembled that of Mount St. Helens in 1980, began with a debris avalanche produced by the edifice collapse that was accompanied by a possible lateral blast and followed by the emplacement of 1 cu km of pyroclastic flows related to growth of the summit lava dome. No historical eruptions have been documented from Yantarni.---
