Kanaga Volcano, Alaska, USA
U.S. Fish and Wildlife Service photo (fair use policy)
Kanaga is near the middle of the Aleutian Islands chain in the North Pacific ocean, in the Andreanof Islands. It's a young stratocone in the middle of the ruins of an earlier volcano named Kanaton. Like most young and active volcanoes, it has a well-formed cone shape, and like all the Aleutian volcanoes it is the product of arc volcanism.
Kanaga has erupted seven times since Europeans came to this part of the world in the mid-1700s. The last time was in 1994, when this photo was taken.
