The Doña Juana complex in Colombia is shown in this September 2017 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 8 km across). The summit area is shaped by a large scarp that has been infilled by lava domes, which have subsequently undergone collapse events to produce block-and-ash flow deposits.

Resumen geológico

The forested Doña 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 took place during a long-term eruption from 1897-1906, when growth of a summit lava dome was accompanied by major pyroclastic flows.
