Cerro Azul (Ecuador volcano)
Cerro Azul is a shield volcano on the south western part of Isabela Island in the Galápagos Islands. At a height of 1,689 m (5,541 ft) it is the second highest peak in the Galapagos and due to its topographic prominence of over 1,500 m (4,921 ft) it is categorised as an ultra. The volcano is one of the most active in the Galapagos, with the last eruption between May and June 2008.

A shield volcano is a type of volcano named for its low profile, resembling a shield lying on the ground. It is formed by the eruption of highly fluid lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form.
