Details for: Almolonga
The rounded hills in the middle of the photo are part of a chain of lava domes of the Almolonga volcanic field. Collapse of Almolonga stratovolcano sometime prior to 85,000 years ago formed a 3.3-km-wide caldera that is surrounded by a ring-dike configuration of dacitic and rhyolitic lava domes, seen here from the east. The youngest and only historically active dome complex is Cerro Quemado, on the right-center skyline, right of conical Santa MarĂ­a stratovolcano. The latest eruption of Cerro Quemado in 1818 produced a blocky 2.5-km-long lava flow on its east flank. Photo by Lee Siebert, 1988 (Smithsonian Institution).
