BackgroundSiete Orejas is an andesitic stratovolcano with a large caldera breached to the south. The volcano overlooks Quetzaltenango, Guatemala's second largest city. The broad irregular summit profile gives the volcano its name, which means "seven ears." The latest eruption of Siete Orejas produced a widespread airfall-pumice and pyroclastic-flow deposit that is stratigraphically constrained to have been formed between 126,000 and 85,000 years ago. Volcán Chicabal, located immediately west of Siete Orejas, was constructed within a 4-km-wide breached scarp of unknown origin. This stratovolcano of unknown age has a well-preserved summit crater containing a crater lake.
