Deposits of the Liberia Tuff are exposed in gullies SW of Rincon de la Vieja. The ignimbrite was emplaced about 1.6 million years ago and covered an area of 3,500-4,000 km2. Eruption of the 25 km3 ignimbrite was associated with formation of the 15-km-wide Guachipelín caldera, inside which the modern Rincón de la Vieja massif was constructed.
