Weak strombolian activity at the New SE Crater
Update Wed 25 Nov 21:28Since this afternoon there is a change visible in Etna's activity. Weak strombolian activity has started from the New SE crater. The activity probably started earlier today, but due to bad weather it was not observed before.
Weak strombolian activity continues also from the vent inside the Voragine crater.
Tremor remains low at the moment.

Update Wed 18 Nov 22:52Strombolian activity continues in the Voragine. Hot fumaroles are visible at the New SE crater.
Degassing from summit craters, mild strombolian activity in Voragine
Update Tue 17 Nov 15:44No significant change in activity has occurred during the past days. Degassing from the New SE crater has decreased again, probably because the magma column has dropped again, and tremor is currently low.
Mild strombolian explosions seem to continue from Voragine, as suggested by small puffs of ash visible. Strong degassing and perhaps dilute ash emissions are also originating from the NE crater where deep-seated explosive activity occurs and can be heard when on its rim.

Tremor amplitude (ESLN station, INGV Catania)
Over the past two weeks, 5 episodes of increased tremor and increased degassing occurred from the crater, but so far all ended without an eruption - one could call them "failed attempts" to produce the otherwise typical paroxysms. Another such episode might be about to start at the time of this update (check the webcams).
In the meantime, weak strombolian activity continues at the vent inside the Voragine crater.
Tremor dropped - no eruption

Etna's current tremor signal (EBCN station, INGV Catania)
urrently, this consists of mild strombolian explosions inside the Voragine summit crater.
Rising tremor - possible sign of a new paroxysm?

Thermal image of the New SE crater
So far, no significant activity is visible from the New SE crater (NSEC), although a hot spot is present on thermal webcam images.

Unstable tremor, continuing strombolian activity in Voragine
Update Sun 08 Nov 08:23Etna remains highly restless. A peak in volcanic tremor occurred last night but with no visible changes in surface activity. Weak strombolian activity continues from the vent inside the Voragine summit craters.
The New SE crater has been restless, too: a small explosion occurred over night.
Another change noted when Emanuela climbed the summit crater was that the wall dividing the two vents inside Bocca Nuova has collapsed, probably a week ago when a seismic-volcanic event occurred at the volcano.
