Difficult to access in this season, the Copahue volcano is an elongated composite cone built in the 6.5 km / 8.5 km Trapa-Trapa caldera, formed between 600,000 and 400,000 years ago, near the northwestern edge of the caldera Caviahue. The summit crater, belonging to a line of nine craters aligned ENE-OSO and 2 km long, is home to an acid crater lake, displaying intense fumarolian activity.
Low to moderate eruptions have been recorded at Copahue since the 18th century; The eruptions of the crater lake in the 20th century ejected pyroclastic rocks and fragments of sulfur. The last eruptions concern the acid lake, also referred to as El Agrio or Del Agrio. They date from 07.2000 to 10.2000; 12.2012-12.2013; 07.2014-12.2014; And 09,2015-12,2016. (GVP)
