Kiska Volcano

Kiska Volcano is a stratovolcano, 8.5 by 6.4 km (5.3 by 4.0 mi) in diameter at its base and 1221 m (4006 ft) high, on the northern end of Kiska Island.

An explosive eruption occurred on January 24, 1962 accompanied by lava extrusion and the construction of a cinder cone about 30 m high at Sirius Point on the north flank of Kiska Volcano, 3 km from the summit of the main cone (Anchorage Daily News, January 30, 1962). A second eruption that produced a lava flow was reported to have occurred March 18, 1964 (Bulletin of Volcanic Eruptions, 1964).

Since then the volcano has emitted steam and ash plumes as well as smaller lava flows.
