Volcán Macá is a large glaciated active stratovolcano in the southernmost part of the South Andean Volcanic Zone, Chile, NW of Puerto Aisén. It is the highest volcano between Lanín and Lautaro volcanoes.
Along with Cay and Hudson volcanoes, Maca is one of the central volcanoes on the axis of the Andean volcanic arc. Maca volcano is located 230 km east of the Chile trench where the oceanic Nazca Plate starts to be subducted into the mantle underneath the South America Plate.
There are no historic eruptions, but young tephra layers have been found that indicate that the volcano is only dormant.
