The Fuego-Acatenango massif comprises a string of five or more volcanic vents along a north-south trend that is perpendicular to that of the Central American Volcanic Arc in Guatemala. From north to south, known centres of volcanism are Ancient Acatenango, Yepocapa, Pico Mayor de Acatenango, Meseta, and Fuego. Volcanism along the trend stretches back more than 200,000 years. Although many of the centres have been active contemporaneously, there is a general sequence of younger volcanism, from north to south along the trend.
