Doña Juana volcano, Colombia

The forested Dona Juana stratovolcano contains two calderas, breached to the NE and SW.

The summit of the andesitic-dacitic volcano is comprised of a series of post-caldera lava domes.

The older caldera, open to the NE, formed during the mid-Holocene, accompanied by voluminous pyroclastic flows.

The younger caldera contains the active central cone.

The only historical activity of Dona Juana took place during a long-term eruption from 1897-1906, when growth of a summit lava dome was accompanied by major pyroclastic flows.
