Based on satellite and webcam images, the Buenos Aires VAAC reported that during 27-30 October gas and water vapor plumes with minor ash content remained near Copahue's summit. The plumes drifted NE on 27 October and E on 30 October.
The Buenos Aires VAAC reported that on 23 September the webcam at Copahue recorded steam-and-gas emissions possibly containing minor amounts of ash.

Strombolian activity continues in the El Agrio crater at fluctuating, generally low intensity.
OVDAS- SERNAGEOMIN reported that during 16-30 June the eruption at Copahue was characterized by phreato-magmatic explosions and Strombolian activity. On 4 July, SERNAGEOMIN posted on their social media page photos from an overflight showing Strombolian activity from a crater atop of a pyroclastic cone which was forming on the floor of El Agrio crater. Based on webcam and satellite views, the Buenos Aires VAAC reported that during 7-8 July diffuse gas-and-steam plumes with minor amounts of ash rose to an altitude of 3 km (10,000 ft) a.s.l. and drifted E and SE.

The new spatter cone in strombolian activity inside Copahue's intra-crater cinder cone on 3 July 2016 (SERNAGEOMIN)
During the past weeks, activity in the volcano's summit crater El Agrio has gradually changed and become magmatic. SERNAGEOMIN scientists published an aerial picture of the crater with a small new spatter cone around a vent ejecting pulsating bursts of incandescent lava, so-called strombolian activity.

Weak steam/ash plume from Copahue this morning
The activity at the volcano, near-constant degassing with sometimes ash emissions, has decreased over the past weeks. Ash venting has become less frequent and intense, and the glow from E Agrio crater that had been visible at the crater disappeared.
