About Unnamed
Unnamed is a pyroclastic cone rising to 4,652 meters (15,263 feet) in Argentina'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
Unnamed is located in Argentina, within the Central Andean Volcanic Arc of the broader South America Volcanic Regions. Situated at 25.08° S, 68.27° W in the Southern Hemisphere, the volcano lies within a subtropical climate zone. Standing at 4,652 meters above sea level, Unnamed towers above the alpine zone, where vegetation gives way to bare rock, snow, and ice for much of the year. The high elevation means the upper slopes experience significantly colder temperatures than surrounding lowlands. The volcanic landform is characterized as a minor, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Unnamed 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 Argentina near Unnamed, 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
An isolated basaltic andesite cinder cone was constructed on top of Miocene ignimbrites and lava flows between the Corrida de Cori range on the Chile/Argentina border and the Salar Río Grande in Argentina. Blocky lava flows from the cone descended in a broad lobe to the SE and in a narrow tongue to the E nearly to the Salar Río Grande. A second smaller vent lies about 800 m NW of the cinder cone. The relatively fluid lava flows display surficial breadcrust textures and were considered by Richards and Villeneuve (2002) to be very young, possibly of Holocene age.
