The beautifully symmetrical Agua volcano towers to 3760 m above the near-sea-level Pacific coastal plain to its south. Activity at Agua has continued into the Holocene, but no historical eruptions are known. The foreground surface is part of a massive Escuintla debris-avalanche deposit most likely produced by collapse of the Acatenango-Fuego massif, out of view to the left.
