Cerro Panizos

fWotD Episode 3382: Cerro Panizos Welcome to featured Wiki of the Day, your daily dose of knowledge from Wikipedia's finest articles.The featured article for Saturday, 8 August 2026, is Cerro Panizos.Cerro Panizos (Spanish: [ˈse.ro paˈni.sos], "Maize Hill") is a late Miocene-age shield-shaped volcano spanning the Potosi Department of Bolivia and the Jujuy Province of Argentina. It features two calderas (depressions formed by the collapse of a volcano) and a group of lava domes. It is part of the Altiplano-Puna volcanic complex (APVC), a group of calderas and associated ignimbrites (a form of volcanic rock) that erupted during the past ten million years. Cerro Panizos is part of the Central Volcanic Zone (CVZ), a volcanic arc that extends from Peru to Chile which was formed mostly by subduction of the Nazca Plate beneath South America.Volcanic activity commenced in the APVC about ten million years ago, producing the large volcanic calderas Panizos, Vilama, Cerro Guacha and the volcano Uturuncu. The formation of the APVC has been linked to the existence of a giant magmatic body in the crust of the Central Andes.The Cienago Ignimbrite erupted over 350 cubic kilometres (84 cu mi) from Panizos about 7.9 million years ago, and 6.7 million years ago the Panizos Ignimbrite erupted over 650 cubic kilometres (160 cu mi). The Panizos Ignimbrite has been noted for volcanic rocks containing orbs. Several volcanic cones such as Limitayoc were active between the ignimbrite eruptions, and a plateau of lava flows and lava domes formed in the central area of the Panizos Ignimbrite after the last eruptions.This recording reflects the Wikipedia text as of 00:44 UTC on Saturday, 8 August 2026.For the full current version of the article, see Cerro Panizos on Wikipedia.This podcast uses content from Wikipedia under the Creative Commons Attribution-ShareAlike License.Visit our archives at wikioftheday.com and subscribe to stay updated on new episodes.Follow us on Bluesky at @wikioftheday.com.Also check out Curmudgeon's Corner, a current events podcast.Until next time, I'm standard Raveena.
