Overview

The monogenetic Huambo volcanic field lies SSE of the Andahua-Orcocampo volcanic field, west of Sabancaya volcano. The field is divided into two segments. The southern area contains several cinder cones and associated lava flows, some of which are inferred to be of early to late-Holocene age on the basis of morphological criteria.

The northern part contains a single vent, the Cerro Keyocc cinder cone, which produced an extensive lava field that covered a plateau to the north during an eruption radiocarbon dated at about 2,650 years ago.

Regional Volcanic Activity

The South America Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

About the Photo

Several scoria cones of the Huambo volcanic field are visible in this July 2020 Planet Labs satellite image monthly mosaic (N is at the top; the image is approximately 40 km across). It has a northern and a southern field and contains up to 60 cones that span 300 to 1,200 m in diameter and up to 300 m in height. The upper area of this image N of the lake contains lava flows erupted from Cerro Keyocc the northern part of the field.
