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) of mountains farther west, leading to a lack of glaciation at the numerous summits exceeding in altitude around the lake. Most of the lake water comes from snowmelt; for much of the year the landscape around the lake is covered with snow. The area of Laguna del Maule was glaciated during the last ice age, with a maximum occurring between 25,600±1,200 and 23,300±600 years ago. Probably due to changes in the position of the Westerlies, after 23,000 years ago the glaciers retreated above Laguna del Maule. The glaciation has left moraines and terraces in the area, with undulating hills lying
