San Agustin, Cerro is located in Bolivia, within the Central Andean Volcanic Arc of the broader South America Volcanic Regions. Situated at 21.25° S, 67.75° W in the Southern Hemisphere, the volcano lies within a tropical climate zone. Standing at 4,980 meters above sea level, San Agustin, 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 composite, 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) considered the andesitic-to-dacitic Cerro San Agustín stratovolcano to have been active during the past 2000 years, but de Silva and Francis (1991) noted no evidence from analysis satellite images of Holocene activity in this area, and de Silva (2007 pers. comm) considered the volcano to be of Pleistocene age.
