Negra Muerta volcanic complex

Negra Muerta is a caldera in Argentina. It is part of the volcanic centres of the Andean Volcanic Belt, which has formed a number of calderas in large ignimbrite producing eruptions. These calderas include Aguas Calientes, Cerro Panizos, Galan, Negra Muerta and La Pacana. Some of these volcanic centres appear to be associated with large fault zones that cross the Puna. ()
