Data from the Global Volcanism Program of the Smithsonian Institution

Details for: Madeira

Funchal, the capital city of Madeira, blankets the SE flanks of the massive shield volcano forming the island. The scenic island, sometimes known as the Pearl of the Atlantic, is the emergent summit of a volcano constructed along an East-West trending rift zone. Following a period of extensive erosion, renewed eruptions produced cinder cones and lava flows that traveled down dissected valleys. Photo by Paul Bernhardt.
