Bogoslof is the emergent summit of a large submarine stratovolcano that rises ~1,800 m above the Bering Sea floor, but is only ~90 m above sea level (a.s.l.) at its highest point. Bogoslof volcano is located slightly north of the main Aleutian volcanic front, about 100 km west of Dutch Harbor, Alaska. Bogoslof began its most recent eruption on December 20, 2016. The volcano has produced several explosions with volcanic clouds reaching as high as 11 km (36,000 ft) a.s.l.
