Korovin Volcano

Korovin Volcano stands on the northeastern part of Atka Island in Alaska’s Aleutian chain near the town of Atka. At 5,030 feet, it is the island’s highest point and one of four volcanic centers in the Atka Volcanic Complex, which also includes Mount Kliuchef, Konia Volcano, Sarichef Volcano, and the Atka Caldera. Korovin is the complex’s most active vent, with fumaroles and hydrothermal vents regularly steaming from it and nearby Kliuchef. Although recent activity has been minor, short-lived explosions occurred from its summit crater lake in 2024 and 2025. Its height, closeness to Atka, and persistent unrest make it a significant feature of the Aleutian volcanic landscape.
