Global Volcanism Program | Image GVP-07067

The Cervantes lava flows formed this uneven terrain on the south flank of Irazú. This massive flow deposit originated from two vents, Cerro Pasquí and another to the NW, producing the eastern and western Cervantes flows, respectively. The former traveled about 10 km to the base of the volcano. These flows are geochemically different, with the 0.17 km3 western flow being basaltic in composition and the 0.9 km3 eastern flow basaltic andesite. Radiocarbon ages for the flows range between about 14,000 and 17,000 years ago. Photo by Guillermo Alvarado, 1986 (Instituto Costarricense de Electricidad).
