Bogoslof Island

The submarine volcano at Bogoslof Island in the Aleutian Chain has gone Red twice in two days. An ash plume was sent up 34,000 feet on Wednesday, causing some concern for passing aircraft.

Bogoslof Island was first mapped after it’s eruption in 1796. The 173 acre island has seen six eruptions since then, from various vents. The island rises to 490′ above sea level, but approximately 6000′ from the seabed.

“Castle Rock”, as seen above, is the eroded remnant of a dome from the 1796 eruption. Currently, AVO has downgraded the alert level to Orange.
