Pululahua caldera (Pichincha, Ecuador)

The Pululahua caldera, Ecuador.

Volcano: Pululahua (see Pululahua at the Smithsonian Institution website in a new tab)
Type: Soil Diffuse Emission
Description: The Pululahua volcano is located on the eastern rim of the western Cordillera, 10 km north of Quito and just north of the equatorial line. This volcano has a 5 km wide, horseshoe-shaped caldera, opened on its western side with an area of some 19 km2, and is filled by volcanic domes and pyroclastic material of different ages. The diffuse degassing structures at Pululahua appear following the inner caldera rim, which indicates that diffuse degassing is structurally controlled.
