Details for: Shishaldin

Often compared to Mount Fuji of Japan, the symmetrical Shishaldin volcano, located on central Unimak Island in the Aleutians, rises 2857 m above sea level. The volcano has a summit crater that emits a nearly continuous plume of steam. Shishaldin is the highest and one of the most active volcanoes of the Aleutian Islands. It has produced frequent strombolian eruptions, sometimes with lava flows, since the 18th century.
