A unique volcano La Pava-Ramadas is found north of Queva and has generated ash falls as far as the Subandean ranges 8.75 million years ago. The volcano was formed on top of the Calama-Olacapato-El Toro lineament. El Queva is one of many volcanoes in the Puna. Previous volcanism occurred in the east at the Aguas Calientes caldera and probably migrated later to El Queva.
