Data from the Global Volcanism Program of the Smithsonian Institution
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.

Pululahua is a relatively low, forested volcano about 15 km N of Quito. The 5-km-wide summit caldera is narrowly breached to the west and partially filled by a group of dacitic lava domes. Pre-caldera lava domes of different ages are found outside the caldera to the E, SE, and S. Four post-caldera domes rise up to 450 m above the caldera floor. Large explosive eruptions producing pyroclastic flows took place during the late Pleistocene and Holocene. Caldera formation took place during a series of eruptions lasting 150-200 years beginning about 2,650 radiocarbon years ago. The latest dated eruption occurred from the post-caldera lava domes about 1,670 years ago and produced lava flows and pyroclastic flows.
