About Moiro, Cerro
Moiro, Cerro is a pyroclastic cone rising to 4,250 meters (13,944 feet) in Bolivia's South America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Moiro, Cerro is located in Bolivia, within the Central Andean Volcanic Arc of the broader South America Volcanic Regions. Situated at 21.68° S, 67.47° W in the Southern Hemisphere, the volcano lies within a tropical climate zone. Standing at 4,250 meters above sea level, Moiro, Cerro towers above the alpine zone, where vegetation gives way to bare rock, snow, and ice for much of the year. The high elevation means the upper slopes experience significantly colder temperatures than surrounding lowlands. The volcanic landform is characterized as a minor, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
The International Association of Volcanology and Chemistry of the Earth's Interior data sheets (1973) listed Cerro Moiro (also known as Cerro Negro) in SW Bolivia as being active during the past 2000 years, but de Silva and Francis (1991) found no evidence from satellite image analysis of Holocene activity. Later higher-resolution satellite imagery suggested a possible Pleistocene age (de Silva 2007, pers. comm.). The andesitic scoria cone was constructed on a rhyolitic ignimbrite plateau.
