About Miniques
Miniques is a stratovolcano(es) rising to 5,910 meters (19,391 feet) in Chile's South America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Miniques is located in Chile, within the Central Andean Volcanic Arc of the broader South America Volcanic Regions. Situated at 23.82° S, 67.77° W in the Southern Hemisphere, the volcano lies within a subtropical climate zone. At 5,910 meters above sea level, Miniques reaches well into the permanent snow and ice zone. Glaciers and snowpack on the upper slopes create the potential for lahars — destructive volcanic mudflows — during eruptions, as heat rapidly melts ice and snow. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Miniques sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Chile near Miniques, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
Volcán Miñiques is a large basaltic andesite to dacitic volcanic complex S of Laguna Miscanti and Laguna Miñiques. The summit is cut by three overlapping craters. Larger craters, partially filled by lava domes and flows, are located W and NE of the summit. The stratovolcano and lava-dome complex was considered to have been active from the Pliocene to the Holocene (González-Ferrán, 1995); de Silva (2007 pers. comm.) assigned it a possible Holocene age. A prominent lava flow extends NW from the summit to the lower flanks, separating Laguna Miñiques from Laguna Miscanti.
