The Meteosat-11 Volcanic Ash RGB image (Figure 1) and animation (Figure 2) shows the first phase of the eruption, from 24–25 December.
In the following days Etna only released a quite strong S02 plume (green), no red-to-yellow ash signal was detected in the plume any more. In the new year the activity appeared to have weakened considerably or stopped altogether.
In the animation pan-African-like colours of red-gold-green show that ash and S02 travelled eastwards across the central Mediterranean.
