Details for: Kiska
A steam plume rises from the summit of conical Kiska volcano, the westernmost historically active volcano of the 2500-km-long Aleutian arc. Three sides of the volcano, including the northern side seen here, are bounded by steep cliffs up to 450 m high. An elliptical crater, breached to the north, caps the stratovolcano, which occupies the northern tip of the elongated island. A flank cinder cone formed in 1962 at the northern coast. Photo by E.V.
