The eastern summit crater has an acid 300 m wide crater lake known as El Agrio or Del Agrio which has intense hydrothermal activity. Infrequent mild-to-moderate explosive eruptions occurred in historic time. Eruptions in the last century have ejected pyroclastic rocks and chilled liquid sulfur fragments. The last one was in 2000. Background:Volcán Copahue is an elongated composite cone constructed along the Chile-Argentina border within the 6.5 x 8.5 km wide Trapa-Trapa caldera that formed between 0.6 and 0.4 million years ago near the NW margin of the 20 x 15 km Pliocene Caviahue (Del Agrio) caldera. and displays intense fumarolic activity. Acidic hot springs occur below the eastern outlet of the crater lake, contributing to the acidity of the Río Agrio, and another geothermal zone is located within Caviahue caldera about 7 km NE of the summit.(Smithsonian / GVP volcano information) |
