Large lava flow to the SW side
Update Sun 01 Feb 23:43
More details start to emerge about the new eruptive phase. Strombolian activity from the SE crater accompanies important lava effusion, feeding an impressive lava flow.
The lava flow has been taking a path to the SW, passing the 2002 cones on their western side and descending already to approx. 2000 m or less altitude, a few km west of the provincial road to La Sapienza.

Strombolian eruptions and lava flow
Update Sun 01 Feb 19:32
The new eruptive phase continues. Dense cloud cover has prevented detailed observations, but from occasional clearings and other observations, it seems that the intense strombolian eruptions are going on from a vent between the old and New SE crater, feeding a lava flow, at least 2.5 km long onto the southwestern slope.
Tremor remains high.

After a few days of apparent calm, new activity resumes on Etna: Seismic tremor started to rise steeply this morning about 6:00 (local time). At the moment it is still elevated with an overall increasing tendency.
Unfortunately, the weather is very bad to see what is going on.
Ash fall was reported in the east sector of the volcano.
Sporadic ash emissions from North East crater

Unrest continues at the summit craters. After strombolian activity from the Central Crater (Voragine) had ceased around 13 Jan, weak ash emissions occurred from the North-East crater yesterday.
Tremor remains elevated.
