Sintesi geologica
Tinguiririca is composed of at least seven Holocene scoria cones W of the Chile-Argentina border constructed along a NNE-SSW fissure over an eroded Pleistocene stratovolcano. The complex was constructed during three eruptive cycles dating back to the middle Pleistocene. The latest activity produced a series of youthful small stratovolcanoes and craters, of which the youngest appear to be Tinguiririca and Fray Carlos. Constant fumarolic activity occurs within and on the NW wall of the summit crater. Hot springs and fumaroles with sulfur deposits are found on the W flanks of the summit cones. A single historical eruption was recorded in 1917.

Riassunto in ingleseTinguiririca Volcano is a massive and active stratovolcano located in Chile's VI Region (O'Higgins) near the Argentinian border. Constant fumarolic activity occurs within and on the NW wall of its summit crater and hot springs and fumaroles can also be seen on the western flanks, as illustrated by the image on the right. It was near this volcano that the Uruguayan Air Force Flight 571 crashed in 1972, and those passengers who had survived the crash were lost for 72 days.
