Background
Geologically, Korovin belongs to the Atka volcanic complex on northern Atka Island. The Atka complex comprises a broad ancient central shield volcano, upon which a larger stratovolcano had been built destroyed by caldera formation about 300,000 to 500,000 years ago.Korovin has two summit vents 0.6 km apart. The northwestern summit vent is a symmetric cone with a small crater. The southeastern summit vent is on the remnant of a cone with a steep-walled crater, about 1 km wide at the rim and at least several hundred meters deep with vertical crater walls. It contains a turquoise green lake with solfataric activity.
