Description

The Guagua Pichincha, whose meaning would be "child" or "baby" Pichincha, is part of the mace of Pichincha, together with the Ruco Pichincha (4698m) and the Padre Encantado. These three mountains are especially visible from the south of Quito, sometimes with a layer of snow in their upper parts. The Guagua Pichincha volcano consists of a dome, called Cristal, located inside a sliding escarpment that has a horseshoe-shaped open to the west. Other more ancient and much larger eruptive centers like Toaza, Basal Guagua and Rucu are located east of the active volcanic center whose fumaroles are usually very noticeable.

The Guagua Pichincha is formed mostly by rocks of dacitic composition. Several of the eruptions of the last ten thousand years were very explosive and caused ash falls, pyroclastic flows, as well as lava domes that subsequently collapsed.

Volcanology

During the prehistoric times the eruptions of greatest magnitude were those that occurred 3700 and 1000 years ago. The historical eruption of the year 1660 was also very important, albeit of lesser magnitude than the preceding ones. In all the events there were major ash falls in the city of Quito, as well as pyroclastic flows, dome collapses and secondary lahars generation in various sectors of the volcano (Robin et al., 2010).

During the investigations carried out in excavations at the valley of Quito, a large evidence of deposits of these falls of ashes and secondary lahars have been found. The fall related to the eruption of 1000 years has a thickness of 12 cm at the area of the Central University. In the historical center, the fall associated with the eruption of 1660 has a thickness of 4 cm.

The Guagua Pichincha has been in great activity since 1999, having had its strongest eruption on May 25, 2001, at that time a cloud of ash rose to a height of 8.5 km.
