An ash plume in 1991 rises above Barren Island along the volcanic arc connecting north of Sumatra. The 3-km-wide island contains a 1.6-km-wide crater that is partially filled by a scoria cone that has been the source of eruptions since the first was recorded in 1787. Lava flows reached the coast during several recent eruptions. Photo courtesy of D. Haldar, 1991 (Geological Survey of India).
