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
Washdyke Lagoon erosion in order for the lagoon to remain separate from the ocean. This balance is also effected by sea level changes, rising causing the barrier to be overtopped and falling allowing a smaller barrier keep the lagoon separate. There are many examples of these relatively closed lagoon systems around the world. Most have significant ecological value, so preserving the balance between fresh and salt water is important. Examples include the Coorong, Australia, 260 km, Laguna de Araruama (Brazil, 10,360 km), Lake St. Lucia (South Africa, 312 km) and Lake Songkhla (Thailand, 1,040 km).
