The conical island of Nevis, lying across a narrow channel from St. Kitts (St. Christopher) Island, is a composite cone with overlapping summit craters. An unnamed lava dome is located NE of the rims of the two craters. Nevis Peak, the 985 m high point of the island, is located on the outer crater rim. The inner crater truncates the western rim of the earlier crater and is widely breached on the west side.

La Soufrière de la Guadeloupe volcano occupies the southern end of Basse-Terre, the western half of the butterfly-shaped island of Guadeloupe. Construction of the Grand Découverte volcano about 0.2 million years ago (Ma) was followed by caldera formation after a plinian eruption about 0.1 Ma, and then by construction of the Carmichaël volcano within the caldera. Two episodes of edifice collapse and associated large debris avalanches formed the Carmichaël and Amic craters about 11,500 and 3100 years ago, respectively. The presently active La Soufrière volcano subsequently grew within the Amic crater. The summit consists of a flat-topped lava dome, and several other domes occur on the southern flanks. Most historical eruptions have originated from NW-SE-trending fissure systems that cut across the summit and upper flanks. A relatively minor phreatic eruption in 1976-77 caused severe economic disruption when Basse-Terre, the island’s capital city, which lies immediately below the volcano, was evacuated.

Liamuiga Volcano is located at the NW end of St. Kitts Island. Two lava domes are located on the upper western flank. The most recent major eruptions less than 2000 years ago produced pyroclastic flows and mudflows. Fumaroles are active in the summit crater.
 The interior walls of Mount Liamuiga (Don Kelloway) The central cone consists of basalt and andesite lavas, and the lower ground around the cone is made up of mainly pyroclastic deposits. Eruptive rocks from Mt Liamuiga range from basalt to andesite, with basalts and basaltic andesites making up 30% of the total volume. Mt Liamuiga rocks show phenocryst distributions and compositional ranges that are comparable with those found in other Lesser Antilles volcanoes.

 The Quill The Quill is a large dominantly andesitic stratovolcano that forms the SE end of St. Eustatius (Statia) Island. The 601-m-high volcano was formed about 32,000-22,000 years ago by rhyolitic eruptions on a shallow-water limestone bank 3 km offshore of an older 0.2 million years old volcanic center exposed at the NW end of the island. The interaction of rhyolitic magma with sea water produced pyroclastic-surge deposits, rich in limestone fragments, that joined the two islands and blanket the entire slopes of The Quill. The surges also swept across the older island and incorporated carbonized plant remains, shell fragments, and remains of fossil hermit crabs. A likely cryptodome tilted up limestones at Sugarloaf on the southern coast. A steep-sided crater, 760 m wide and more than 300 m deep caps The Quill; a notch on the western rim of the crater has directed the youngest pyroclastic flows towards the island’s capital, Orangestad. The last dated eruption of The Quill produced pyroclastic flows about 1600 years ago.
