Etna volcano eruptions:
Near continuously active; some major historic eruptions include 122 BC (large Plinian outbursts that created the small caldera of the "Cratere del Piano"), 1669 AD (devastating flank eruption that destroyed 15 villages and part of Catania), 1787 (Subplinian eruption and one of the most spectacular summit eruptions on record - lava fountains reportedly up to 3000 m high).
Eruptions since 1950 (f: flank / s: summit activity): 1950 (s), 1950-51(f), 1955 (s), 1956 (s), 1956 (f), 1957 (s),1960 (s), 1961 (s), 1964 (f), 1964 (s), 1966 (s), 1966-1971(s), 1968 (f), 1971(f), 1972-1973 (s), 1974 (f), 1974-1975 (s), 1975-1977 (f), 1977-1978 (s), 1978 (f), 1979(s), 1979 (f), 1980 (s), 1981 (s), 1981 (f),1982-1983 (s), 1983(f), 1984(s), 1985(s), 1985(f), 1986(s), 1986-1987 (f), 1987(s), 1988(s), 1989(s), 1989(f), 1990 (s), 1991-93(f), 1995(s), 1996(s), 1997 (s), 1998 (s), 1999 (s), 2000 (s), 2001(s), 2001 (f), 2002(s), 2002-03(f), 2004-2005 (f), 2006 (s), 2007 (s), 2008-2009 (f), 2010(s), 2011-2013(s), 2014-ongoing(f)
 
Typical eruption style:
Effusive (lava flows) and mildly explosive (strombolian) eruptions. Both summit and frequent flank eruptions, the latter seem to be occurring in clusters lasting few to a few tens of years.

The 21st paroxysm at the New SE crater which started last evening is still going on although it has decreased a bit. Until now, the eruption has been rather weak with no sustained tall lava fountains as during most of the paroxysms. Instead, the New SE crater continues to produce loud, spectacular near-continuous strombolian-type jets (or low, pulsating fountains) and explosions of lava bubbles. The eruption so far: Over the course of the night, it has effused 3 lava flows towards the Valle del Bove:

The 21st paroxysm at the New SE crater is in progress, but has still to reach its climax. At the moment, violent continuous strombolian explosions or low pulsating lava fountains occur at the summit vent and a lava flow has started to issue from the fissure vent on the SE flank of the cone.

It seems more and more likely that the next (nr 21 in 2013) New SE crater paroxysm is going to occur in the following hours or so; the tremor continues to climb rapidly and small strombolian explosions are now visible from the summit vent of the NSEC.

This morning at 11:16 (local time), an ash explosion occurred from the New SE crater, accompanied by a rise in tremor. This is similar to the precursory activity of the recent past paroxysms and probably means that the magma column inside the cone's conduit has started to rise and began to clear its way by sporadic, but potentially quite powerful explosions.
Analysis of webcam images also show that weak incandescence appeared at the NSEC during the second half of the night, confirming that the crater is in the process of reactivation.
The next hours or days are likely to be interesting at Europe's most active volcano.

Update Mon 23 Dec 10:04
No significant changes have occurred. Ash emissions, sometimes relatively strong, continued from the NE crater and the tremor shows a very slow gradual rising trend.

The activity has dropped although a small new fissure has now opened on the lower NE side of the cone, producing a small lava flow visible in the picture; whether it is the near end of the current episode or only a pause is difficult to say.

What started as a paroxysm has now become more a dominantly effusive subterminal fissure eruption. Lava effusion continues from the vent at the SE base of the New SE crater, accompanied by strong, fluctuating tremor. Bad weather conditions mostly prevent good views.
We post a new time-lapse video of Etna volcano's New SE crater during the early hours of 15 Dec (Radiostudio7 webcam from Montagnola), showing the opening of the eruptive fissure: before 06:00, the summit (and to its left, the western vent in the saddle) are active with violent strombolian explosions and magma bubbles, and a small lava flow effuses from the summit vent to the SE as a result of overflow. At 06:10, a strong explosion occurs and a fissure opens below the summit vent at on the SE side, producing a new flood of lava in the same path as the previous flow (the fracture on the SE side). This fissure vent propagated further down towards the base of the cone and has continued to produce lava flows until now:

These time-lapse video show the lava flows into Valle del Bove (Etna Trekking webcam from Schiena dell'Asino) and the explosive activity at the summit vent (and occasionally at the western saddle vent), and the strong lava effusion from the flank vent at the SE base over the past 24 hours (INGV Montagnola webcam thermal image).

Tremor has started to decrease, which might be a sign that the peak of the eruption is over, although it could regain again as it has done before. Webcam views are obscured by clouds at the moment.
This is certainly one of the most unusual paroxysms of Etna during the past years: activity has been dominantly effusive and the North-East crater has been active as well, producing weak ash emissions (this comes perhaps not so much as a surprise when taking into account the precursory episode at this crater the day before, 13 Dec).
Satellite data show that the plume of the eruption (mainly SO2 and only small amounts of ash) has drifted by now about 500 km to the east.
Recommended reading: Culture Volcan has posted a beautiful summary of the eruption so far.

"One of Etna's loudest and least visible paroxysms is still continuing rather intensely", twittered Dr. Boris Behncke from INGV Catania about the ongoing eruption. Lava effusion and strombolian activity continued all day and increased drastically during the evening. Weather conditions don't allow very good views, but it appears that the New SE crater is producing pulsating (low) fountains and feeds abundant lava flows headed towards the Valle del Bove from the vent in its SE fissure. The tremor signal is still increasing, suggesting that the peak of the paroxysm is still to come.

The 20th paroxysm at the New SE crater ended at dawn, shortly after reaching its peak. The eruption seems to have been relatively weak (compared to previous paroxysms) and produced only relatively low pulsating lava fountains with associated ash plumes and a small lava flow to the SE towards the Valle del Bove. Tremor has dropped sharply, but at the moment of updating, strombolian explosions, ash emission and the effusion of the lava flow continue at reduced level.
The following time-lapse video, seen as time-lapse from the Radiostudio7 webcam on Montagnola (from S), shows the slow build-up during the day with sporadic explosions, and the pulsating fountaining at night:

In this video (from Radiostudio7's Montagnola webcam south of the summit area), the lava flow on the SE side of the cone can be seen:

After yesterday's deep-seated activity in the NE crater, explosions have started at the New SE crater this morning at 09:25 (local time), when a relatively powerful explosion occurred. The explosion was near the surface and tremor started to rise steeply in correspondence. Although it has now dropped again a bit, it seems likely that the 20th paroxysm at the NSEC is about to occur.

A temporary steep increase in tremor amplitude earlier today (but with no other visual changes) rose some expectations about a new paroxysm, which would be now "due" if Etna kept her rhythm of 5-7 days intervals. However, it turned out to be only a short-lived peak, and it seems we have to wait a bit more. No explosive activity could be identified at the New SE crater.

No significant news from Etna so far. The brilliant weather shows the fiery lady in all her glory today. The latest lava flow towards Valle del Bove from Monday's paroxysm stands out as a dark black tongue against the white snow. Volcanic tremor has increased a bit, showing that the NSEC remains (mostly internally) agitated.
Update Thu 05 Dec 11:50
The New SE crater remains restless. As the following time-lapse video of the past 24 hours shows, there is occasional weak lava extrusion from effusive vents on the upper flanks, and rarely glow from the summit vent suggesting that the magma column is relatively still high inside the vent and sometimes produces deep-seated strombolian explosions.

Update Tue 03 Dec 09:28
Turi Caggegi succeeded in capturing yesterday's lava fountains, several hundreds of meters high and from several vents spraying in different directions, on video:

The eruption is already ending with an abrupt drop of volcanic tremor and decreasing lava emission.
