OVDAS-SERNAGEOMIN reported increased seismicity at Copahue on 22 December. The plumes rose 1-1.5 km above the crater and were observed in satellite imagery drifting 400 km SE.

The first IASI orbit that detects SO₂ is on 22 December 2013 at 13 UTC. The SO₂ mass loading estimated from the IASI measurements around 11 UTC on the 23 December 2012 is 0.7 Tg.
