Cerro Azul Volcano

"The Galapagos Islands are believed to be formed from a mantle plume which creates a hotspot of volcanic activity away from plate boundaries where islands then form above it, similar to process that has created the Hawaiian islands"

"Cerro Azul is one of six coalescing volcanoes on Isabela Island: Ecuador, Wolf, Darwin, Alcedo, and Sierra Negra. Cerro Azul is shaped like a large upturned soup bowl and like the other volcanoes on Isabela Island has a large caldera its one at 4x5 km across is one of the smallest."

"It is estimated that the surface of the volcano is young, less than 5000 years old and it is estimated that the volcano is about 350,000 years old. The age of Cerro Azul is similar to Sierra Negra and Alcedo and their positioning is not believed to be related to plate movement over the magma plume but instead an interaction between the plume and the lithosphere."
