Laguna del Maule is geothermally active, featuring bubbling pools, fumaroles and hot springs. Temperatures in these systems range between but there is no degassing at the surface. The Baños Campanario hydrothermal springs lie northwest from Laguna del Maule and their waters together with these from the Termas del Medano springs appear to form through a mixing of magmatic and precipitation water. The field has been evaluated as a potential source of geothermal energy. It and the neighbouring Tatara-San Pedro volcano form the so-called Mariposa geothermal system discovered in 2009, whose temperature has been estimated on the basis of gas chemistry to be . One estimate puts the potential productivity of Laguna del Maule as an energy source at .
