The SW side of Tristan da Cunha volcano rises above the southern Atlantic seas. The 2060-m-high summit cone towers above high cliffs that bound most sides of the 13-km-wide island. Lava flows dominate both the low-angle base and the steep upper flanks, although pyroclastic cones ringing the central cone are scattered around the lower flanks. The only historical eruption on Tristan da Cunha occurred during 1961 from a northshore vent and forced the evacuation of the island's only settlement.
