Copahue

The volcano features nine crater formations along a 2-kilometer line, with the easternmost crater containing an acidic lake of 300 meters width.

The caldera of Copahue formed approximately 600,000 years ago, generating substantial pyroclastic flows that extended 37 kilometers from the volcanic center.

The name of the volcano comes from Mapuche language, referring to the sulfuric waters that characterize the geological formations in the area.

Regular monitoring by SERNAGEOMIN provides essential updates about volcanic activity levels, helping local authorities make informed decisions about safety measures.

The eastern summit crater contains a lake with an extremely acidic pH level between 0.18 and 0.30, producing pyroclastic rocks and liquid sulfur fragments.
