Funchal, the capital city of Madeira, is seen here along the southeast flanks of the massive shield volcano forming the island. The island is the emergent summit of a volcano that rises about 6 km from the seafloor in an E-W-trending rift zone. Following a period of extensive erosion, renewed eruptions produced cinder cones and lava flows that traveled down dissected valleys.
