Agua volcano (left) rises above the clouds west of Lake Amatitlán, located in the Amatitlán caldera. This 14 x 16 km wide Pleistocene caldera has produced many large explosive eruptions whose deposits underlie Guatemala City and surrounding areas. Pacaya volcano, out of view to the left, was constructed over the buried southern rim of Amatitlán caldera. The 3760-m-high Agua volcano is younger than Amatitlán, but has had no historical eruptions.
