Laguna del Maule (volcano) 2017. The Chilean National Geology and Mining Service monitors the volcano. Laguna del Maule (volcano) Laguna del Maule is a volcanic field in the Andes mountain range of Chile, close to, and partly overlapping, the Chile-Argentina frontier. The bulk of the volcanic field is in the Talca province of Chile's Maule Region. It is a segment of the Southern Volcanic Zone, part of the Andean Volcanic Belt. Many of the volcanic centres in the Laguna del Maule volcanic field formed during postglacial times, after glaciers had retreated from the area. This activity has generated cones, lava domes, lava coulees and
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
