SERNAGEOMIN reported that during 16-30 November continuous ash emissions from explosions at Copahue's El Agrio crater were recorded by the webcam; plumes rose as high as 1.3 km above the crater on 29 November. Satellite images detected ash plumes drifting as far as 560 km SE and ESE. During an overflight on 28 November scientists observed the absence of the acidic lake and a growing pyroclastic cone.

SERNAGEOMIN reported that at 1930 on 19 November tremor amplitude at Copahue began to oscillate. At 0305 on 20 November crater incandescence was coincident with small explosions that produced ash plumes. The Alert Level remained at Yellow; SERNAGEOMIN recommended no entry into a restricted area within 1.5 km of the crater.
