How Lake Atitlan formed
Lake Atitlan sits inside the Atitlan III caldera. The basin formed roughly 84,000 years ago during the Los Chocoyos eruption, one of the largest known eruptions of the past 100,000 years. After the eruption, the magma chamber collapsed and water gradually filled the basin. For the full geology story, read How Was Lake Atitlan Formed? and the broader history guide.
