Laguna del Maule (volcano) early Quaternary volcanic centres, are also found around the field. Northeast of Laguna del Maule is the high Cerro Campanario, a mafic stratovolcano which was active 150,000–160,000 years ago. Nevado de Longavi volcano is located west of Laguna del Maule. The local volcanoes are in a segment of the crust where the Wadati-Benioff zone is deep. Also west of Laguna del Maule lies the Tatara-San Pedro and Rio Colorado caldera; they may be part of a volcano alignment with Laguna del Maule. More distant are the Calabozos caldera and a late Pleistocene system with domes and flows south of Cerro
