Bogoslof Volcano, USA

An aerial view shows the 1992 lava dome of Bogoslof Island, the summit of a largely submarine stratovolcano located in the Bering Sea 50 km behind the main Aleutian arc.

The 1992 lava dome grew to a height of 100 m in July at the northern tip of Bogoslof Island.

The island is about 1.5 x 0.6 km wide, and due to its frequent eruptive activity and energetic wave action, has changed shape dramatically since first mapped in the late 1700's.
