Cerro Azul volcano at the SW tip of J-shaped Isabela Island rises in the distance above the rim of Fernandina caldera.  The flat-topped shield volcano is truncated by a deep, steep-walled 4 x 5 km summit caldera.  A prominent cinder cone is located at the ENE side of the caldera and youthful lava flows cover its floor.  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.
