Presently some summits around Laguna del Maule reach altitudes of . The volcanic field lies at an average height of . Among the various
Laguna del Maule (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 . Subduction of the eastern part of Nazca plate beneath the western margin of the South America Plate occurs at a rate of about , a process which is responsible for events such as the 1960 Valdivia earthquake and the 2010 Chile earthquake. This subduction process is responsible for the growth of the Chilean Andes and the volcanic and geothermal manifestations therein.
