Details for: Pululahua
Pululahua is a relatively low-profile, forested volcano immediately north of the equator, 27 km N of Quito. Loma Pondona (left) and the lower Rumiloma (right center) are two of a group of lava domes that partially fill a 3-km-wide caldera. They are seen here from the SE caldera rim. The caldera was formed during the latest dated eruption about 2,400 years ago. Large explosive eruptions were accompanied by pyroclastic flows during the late Pleistocene and Holocene.

Location: Pululahua caldera (View Details at MaGa DB)
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.
