Antuco Volcano is a stratovolcano located in the Bío Bío Region of Chile, near Sierra Velluda and on the shore of Laguna del Laja.

The first registered eruption occurred in 1624 but it is known that the volcano experienced some activity in the 16th century.

[1] The 1624 eruption was strombolian forming a lava flow and resulting in the ejection of pyroclasts.

[1] Beginning with this eruption many more were recorded as the volcano lies near an Andean mountain pass transited by the Spanish.

The Volcanic Ash Advisory Center in Buenos Aires, Argentina, investigated and determined that only trace gases and steam had emerged from Antuco.
