Cerro Sincholagua (left) and Loma la Marca (right) are the southernmost of a group of lava domes pre-dating the formation of Pululagua's caldera. Seen here from the equator to their south, they are part of a chain of lava domes that were constructed on a roughly N-S line east of the caldera. Cerro Sincholagua forms the highest peak of 3356-m Pululagua volcano.

The flat floor of the 3-km-wide caldera of Pululagua volcano is used for agricultural purposes. This view from the SE caldera rim looks across to Loma El Lavadero on the NE rim, 700 m above the caldera floor. Pululagua's caldera was formed during major explosive eruptions about 2400 years ago that produced plinian airfall deposits, pyroclastic flows, and pyroclastic surges.

Pululagua is a relatively low, forested volcano immediately north of the equator, 27 km north 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 summit caldera. They are seen here from the SE caldera rim. The caldera was formed during the latest dated eruption of Pululagua about 2400 years ago. Pululagua produced large explosive eruptions accompanied by pyroclastic flows during the late Pleistocene and Holocene.
