Huambo volcanic field is a volcanic field in Peru. Andahua-Orcopampa lies north-northeast and Sabancaya east of Huambo,[1] east of the Rio Colca.[2] The town of Huambo lies between the two fields.[3]

The northern part of the field was active 700 BCE ± 50 years, forming a large lava flow field and a cinder cone Cerro Keyocc. The southern part of the field contains other cinder cones and lava flows. Some may be of Holocene age.

Lava flows are a few 10 metres (33 ft) thick. Four among the volcanoes of the southern field are Marbas Grande, Marbas, Marbas Chico I and Marbas Chico II.[2] The formation of these fields may have been influenced by magma ascent along deep fault systems.[4]

Trachyandesite is the major eruption product of Huambo.
