There she blows!
Augustine erupted in 2006, sending an ash cloud 30,000 feet above the sea.

NUMBER AND TYPE
Alaska has more than 100 volcanoes. Seventy-six are in the region of Alaska called the Aleutian Islands. More than 50 are active. Most of these are composite volcanoes, meaning they were formed by alternating layers of lava and rock.
AGE AND HOW FORMED
The majority of the volcanoes in Alaska form the Aleutian Islands. This curved row of volcanoes, known as an island arc, formed about 40 ...
