Doña Juana is a forested stratovolcano 56 km NE of Galeras volcano. The volcano has 2 calderas, the younger of which contains the active summit cone. The only historic eruption started in 1897 and lasted almost 10 years, during which the youngest of several summit lava dome was built. Large pyroclastic flows were produced during this eruption.

Background:

The2 calderas of the andesitic-daciticDoña Juana stratovolcano are breached to the NE and SW. The older caldera, open to the NE, formed only about 5000 years ago during or after an eruption that produced voluminous pyroclastic flows.
