Rather than sustained fountains with significant amounts of liquid lava bombs, it produced mostly a dense ash column that rose up to 6-7 km altitude (much less than during most paroxysms).
Only little glowing material could be seen in the eruption column. Activity waned at around 5 pm., then picked up again during the evening, to continue with less intensity and mild strombolian eruptions during much of the night. It gradually decreased in the early morning hours and seems to have stopped by now.
The small lava flow that had been erupted in the Valle del Bove during the day before yesterday and yesterday has also stopped.
Etna is again calm, but for how long nobody knows...

During 6-7 December Strombolian activity at SEC produced almost continuous ash emissions that dispersed ENE. On 8 December the ash emissions were diffuse and discontinuous, and dissipated near the summit. ... Read all
