Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Azul, Cerro
A large tuff cone occupies the ENE side of the summit caldera of Cerro Azul volcano at the SW tip of Isabela Island. A small caldera bench is seen above the cone at the upper right, and a larger bench on the northern side of the caldera is outlined by the light-colored line below the horizon at the upper left. The 4 x 5 km wide caldera is one of the smallest of the Galápagos shield volcanoes, but its 650 m depth makes it one of the deepest. Youthful dark-colored lava flows at the left cover much of the caldera floor. Photo by Tom Simkin (Smithsonian Institution).

Located at the SW tip of the J-shaped Isabela Island, Cerro Azul contains a steep-walled 4 x 5 km nested summit caldera complex that is one of the smallest diameter, but at 650 m one of the deepest in the Galápagos Islands. The shield volcano is the second highest of the archipelago. A conspicuous bench occupies the SW and west sides of the caldera, which formed during several episodes of collapse. Youthful lava flows cover much of the caldera floor, which has also contained ephemeral lakes. A prominent tuff cone located at the ENE side of the caldera is evidence of episodic hydrovolcanism. Numerous spatter cones dot the western flanks. Fresh-looking lava flows, many erupted from circumferential fissures, descend the NE and NW flanks. Historical eruptions date back only to 1932, but Cerro Azul has been one of the most active Galápagos volcanoes since that time. Solfataric activity continues within the caldera.
