Volcan Tacora  Located in the Arica and Parinacota region
 Approximately 7,000 hectares
 Area mainly tundra and desert (Altiplano)
 Elevation between 4,150 - 5,900 meters

The data of Aguas Calientes thermal springs on the western flank of the Tacora Volcano indicates that they occur probably associated to a NS lineament, which would indicate a structural control of them. Similarly, it is expected that laying down there would be a deep magmatic heat high, this based on the presence of fumarole activity and the deposition of sulfur, associated with the volcano activity. However, the limited chemical data that indicate the presence of acid-magmatic conditions, it is only a first approximation and is possible that these conditions may be restricted and they should therefore even be evaluated.

According to the general knowledge, it was established that waters related to the young volcanoes, including magmatic vapors (H2S, CO2, HCl, SO2), rise towards the surface crossing through the underground water levels, and gases (Cl- and SO2) are absorbed and converted into hydrochloric acid (HCl) and sulfuric acid (H2SO4), producing low pH conditions in the Aguas Calientes springs, and where the fumarole activity would correspond to the flanks of the system.
