Cerro Vilama

Vilama is a Miocene caldera in Bolivia and Argentina. Straddling the border between the two countries, it is part of the Central Volcanic Zone, one of the four volcanic belts in the Andes. Vilama is remote and forms part of the Altiplano-Puna volcanic complex, a province of large calderas and associated ignimbrites that were active since about 8 million years ago, sometimes in the form of supervolcanoes. The Vilama caldera was originally estimated to have a size of 40 by 65 kilometres (25 mi × 40 mi) but the size was later revised to be between 15–18 kilometres (9.3–11.2 mi) and 35–40 kilometres (22–25 mi) and is almost entirely buried beneath younger volcanoes that have grown along the margin of the caldera; volcanic activity on these volcanoes continued into the Pleistocene. Several lakes also developed on the floor of the caldera, which contains a resurgent dome. Vilama is the source of the enormous Vilama ignimbrite, which was emplaced during an eruption with a volcanic explosivity
