stratovolcano
Southern Chile and Argentina (South America), -50.33°S / -73.75°W 
Summit height: 2546 m / 8,353 ft
Current status: normal or dormant (1 out of 5)
Aguilera is a dacitic stratovolcano in the southernmost Chilean Andes and located west of Lake Argentina and NE of Peel Fjiord. Its geologic history is poorly known, but there Aguilera must have had a large explosive eruption less than about 3600 years ago, which left a prominent tephra layer.
Aguilera belongs to the Australandean Volcanic Zone of south Patagonia.

Background
Explosive eruption of Aguilera volcano 3600 years agoA large explosive eruption occurred at Aguilera volcano about 3600 years ago and is recognized by the "A1" tephra layer. The eruption was Plinian in size and erupted ca. 4-9 cubic km of magma. The A1 white tephra layer is deposited in thick sections along the shores of Lago Argentino. It is absent on Tierra del Fuego, but has a very wide distribution north of the Strait of Magellan. At 80 km distance, the airfall tephra layer is still over 10 cm thick and more than 5 cm thick in 130 km distance east of the volcano. This suggests that the wind was blowing from the SW at the time of the eruption and the plume drifted NE.
The pumice of the A1 tephra contains the mineral biotite as phenocrysts, which has not been found in other lavas of Aguilera.

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.

Aguilera Volcano FAQ
+When was the last eruption of Aguilera volcano?
The last confirmed eruption of Aguilera occurred around 1253 BC.
+When was the largest eruption of Aguilera volcano?
The largest eruption known from the younger geological history of Aguilera volcano occurred around 1253 BC. It only has a VEI (Volcanic Explosivity Index) of , likely because it was a mainly effusive eruption generating lava flows but very little ash.
