The New SE crater has remained quiet since yesterday, although seismic activity remains above background. Strong degassing is visible from Bocca Nuova.

Tremor has remained elevated and the New SE crater continued to produce weak strombolian activity and aliment the lava flow during much of the night. At the moment (Sunday morning), it is not clear if this activity is continuing.

Summary of yesterday's paroxysm:
The paroxysm yesterday ended around noon, after about 12 hours total of activity from the New SE crater which consisted in gradually increasing strombolian activity that merged into lava fountains after midnight. The lava fountaining reached its peak in the early morning hours (6-8 am local time) with heights of 4-600 m above the crater.
Strong ash and steam emissions continued to produce an impressive plume rising about 10 km above the volcano, i.e. to an altitude of 13 km (30,000 ft) and drifting SW. A relatively small lava flow was erupted from the saddle vent between the old and new SE crater, traveled south and then east into the upper Valle del Bove, reaching a length of approx. 0.5 km.
One of the most remarkable aspects of this eruption was that starting from 08:23 (local time), the NORTH-East crater activated also and produced a second ash plume.
It is still unclear whether the Bocca Nuova / Voragine craters participated in the activity as well, but it seems that they produced at least strong steaming and some ash as well in the later stages.

Following a slow gradual build-up of increasing strombolian activity at Etna's New SE crater since yesterday, a new paroxysm is now in the progress, with high lava fountains, lava flows, and a tall ash plume.

This would be the 14th paroxysm in 2013, after the series of 13 eruptions during Jan-April. The eruption was also preceded by a swarm of earthquakes.

Update Wed 23 Oct 12:16
After about 10 days of near complete quiet, a faint red glow was observed early on 22 Oct at the New SE crater. The origin of the glow seems to have been increased degassing from the summit vent and the at the fumaroles in the saddle between the old and New SE cone.
