Northeast of Laguna del Maule is the Cerro Campanario, a mafic stratovolcano that is high and was active 150,000-160,000 years ago. The 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 San Francisquito, which are both silicic volcanic systems. The activity of Tatara-San Pedro and Laguna del Maule with the presence of rhyolite may be influenced by the subduction of the Mocha Fracture Zone, which projects in the direction of these volcanic centres. Nearby are the Risco Bayo and Huemul plutons, which are about 6.2million years old and may have formed through volcanism similar to that of Laguna del Maule.
