Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Ascension
A view to the NW from Green Mountain shows The Sisters (left) and Perfect Crater (right-center), cinder cones on the flanks of the Ascensión Island volcano, which lies just west of the Mid-Atlantic Ridge. The isolated island contains numerous cones and lava domes. Many volcanic features on Ascensión have a very youthful appearance, and three eruptions have been dated within the past 2,000 years, the most recent being the South Sisters flow, possibly only 500 years old.
