Cerro Azul - Volcano on Isabella

Cerro Azul, 1640 m high and the second highest peak of the Galapagos archipelago, is a typical shield volcano located at the SW tip of Isabela Island.  It is one of the most active volcanoes of the Galapagos, although historic records of its activity only dates back to 1932.  As most of the other shield volcanoes on the Galapagos island, it has steep-walled 4x5 km nested summit caldera, one of  smallest diameter, but at 650 m one of the deepest in the Galapagos Is.  Young lava flows cover most of the floor of the caldera, where temporary lava lakes are sometimes present during summit eruptions.  Numerous spatter cones from lateral fissure eruptions dot the western flanks of the volcano.  source: www.volcanodiscovery.com/volcano-tours/galapagos/cerro-azul/
