Based on seismicity during 11-12 October, OVDAS-SERNAGEOMIN reported that the eruption from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, continued at a low level. Plumes visible with an area web camera rose no higher than 4 km above the crater during 11-12 October. On 17 October a white plume rose 4.5 km above the crater and a diffuse ash plume observed in satellite imagery drifted 30 km SE.
The next day, a white plume rose 3 km above the crater. Satellite imagery showed a plume drifting 50 km NE, and then later a diffuse ash plume drifting 200 km NE and SE. The Alert Level remained at Red.

According to news articles, several domestic and international flights in Argentina, Brazil, Chile and Uruguay were cancelled on 16 October due to re-suspended ash. OVDAS-SERNAGEOMIN also noted that there was not an increase in volcanic activity, but high winds in the region. Flights resumed the next day.
