Volcanoes of South America
The Galápagos Islands are an isolated set of volcanoes, consisting of shield volcanoes and lava plateaus,  west of Ecuador. They are driven by the Galápagos hotspot, and are between 4.2 million and 700,000 years of age. The largest island, Isabela Island, consists of six coalesced shield volcanoes, each delineated by a large summit caldera. Española, the oldest island, and Fernandina, the youngest, are also shield volcanoes, as are most of the other islands in the chain. The Galápagos Islands are perched on a large lava plateau known as the Galápagos Platform. This platform creates a shallow water depth of  at the base of the islands, which stretch over a -long diameter.
