Copahue-Caviahue Anfiteatro (Neuquen, Argentina)

Copahue's eruption 2013

Volcano: Copahue-Caviahue (see Copahue-Caviahue at the Smithsonian Institution website in a new tab)
Type: Soil Diffuse Emission
Description: The north-western sector of Caviahue caldera (Argentina), close to the active volcanic system of Copahue, is characterized by the presence of several hydrothermal sites that host numerous fumarolic emissions, anomalous soil diffuse degassing of CO2 and hot soils.The gas source is likely related to a relatively shallow geothermal reservoir containing a single vapor phase as also suggested by both the geochemical data from the 3 deep wells drilled in the 1980s and gas geoindicators applied to the fumarolic discharges
