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. You can follow this at live at webcams.volcanodiscovery.com/Etna. 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.

The capricious Sicilian lady seems undecided what to do. The sporadic strombolian activity from the New SE crater has last been observed (to our knowledge) about 2 days ago. Temor is currently low, and generally bad weather doesn't help detailed direct observations.
Update Mon 07 Oct 23:25
Sporadic weak explosions from the New SE crater have continued. Currently, there are no signs of increasing activity.

Weak strombolian activity in both Bocca Nuova and NSEC
Update Sat 07 Sep 12:24
Last night, very deep-seated strombolian activity could be observed from both the Bocca Nuova and the New SE crater. This indicates that (similarly to early this year) magma has risen into the upper parts of the conduits beneath both vents. It might only be a question of time until this activity increases (perhaps even towards new paroxysms) and maybe becomes focused on one of the two craters.
New ash emissions from New SE crater
Update Fri 06 Sep 11:00
Since a few days ago, the New SE crater has been producing weak ash emissions occasionally. Whether this is the precursor to more vigorous activity and when this will occur, is difficult to say at the moment, but it is a sign that the volcano is waking up from the slumber it has been in during the past 4 months.
Update Sun 26 May 11:59
Etna today is free of clouds, but strong winds with gusts up to 70 km/h speed prevail. No further significant earthquakes occurred. The only activity remains degassing, and occasional small explosions, not visible, deep inside Bocca Nuova, based on seismic observations (OPEC).
Update Sat 25 May 18:26
The earthquake swarm on the SE flank seems already to have come to an end. No eruptive activity is currently occurring at the summit craters. Strong wind and cloud cover prevented a field visit today.

A swarm of shallow (3-6 km depth) earthquakes including several felt ones (magnitudes 2.9-3.5) occurred yesterday and today under the SE flank near Zafferana town. So far, no other unusual signs of activity have been reported, but the swarm could indicate something in the making, and the monitoring agency INGV is certainly following these events closely.
Update Thu 23 May 10:42
Etna has been almost completely quiet since a brief episode of strombolian activity at the New SE crater in early May. Apart from a few occasional deep-seated explosions in Bocca Nuova detected only on seismic signals (INGV personal communication), the volcano has not shown other surface activity than degassing.

The 13th New SE crater paroxysm is occurring this evening. Tall lava fountains rise from the central vent of the cone, and a lava flow has rapidly descended the slope into Valle del Bove. A dense tephra plume is rising several kilometers above the volcano and drifting to the NE where ash- and lapilli fall is occurring.

Activity has continued to increase with near continuous strong strombolian explosions from the New SE crater, but it seems that the climax of the paroxysm with sustained lava fountains is yet to come, possibly very soon. The tremor has reached higher levels than during most of the previous paroxysms, but still rises.

Tremor signal (ESLN station, INGV)
Strong strombolian-type explosions, probably accompanied by effusion of small lava flows continued all night from the New SE crater and produced strong glow visible through the fog around the summit. Rumblings were heard in nearby villages, but fog and clouds have been preventing detailed observations. The tremor has risen to high levels comparable with those during previous paroxysms, then decreased a bit and seems now to increase again. This pattern looks very similar to the 12 April paroxysm, one which was preceded by a long phase of very strong explosions, that culminated in lava fountaining only after the tremor had reached its peak.

After only 2 days since the previous eruption, the 12th paroxysm of the New SE crater occurred this afternoon. Following a build-up phase of strombolian explosions since yesterday, the eruption culminated with tall lava fountains and lava flows. At the end of the eruption, at least 2 pyroclastic flows towards the Valle del Bove were reported to have formed. After the eruption, lava flows continue to be active from vents at the base of the cone and descend towards Valle del Bove.

Weak explosive activity persists at the New SE crater, which has been producing small ash emissions throughout the day yesterday. During the night, a small lava flow emerged from the fissure that cuts through the cone on its eastern flank.
11th New SE crater paroxysm
Update Thu 18 Apr 19:18
The 11th paroxysm from the New SE crater occurred as expected today. As during the previous eruption, the build-up phase with increasing strombolian activity was relatively long. The peak phase itself when activity culminated in lava fountains was comparably short.

It seems likely that another paroxysm is in the making at the New SE crater: Strombolian explosions have continued throughout the night and this morning, and have been intensifying. Lava seems to have appeared at several vents on the fissure cutting through the New SE crater and the tremor signal is steeply rising.
Strombolian activity from New SE crater
Update Wed 17 Apr 11:05
New activity has started from the New SE crater last night, when incandescent degassing vents were visible at the crater. This activity has progressively increased during the night and produced strombolian bursts during the second half of the night. Tremor has been showing a slow increase.

Current tremor signal from Etna (ETFI station, INGV Catania)
The 10th paroxysm of the New SE crater has ended after a long phase of strong explosions, lava flows, lava fountains and a tall ash plume.
The style of this latest eruption was distinctively different from the preceding ones and suggests that Etna is in a period of change. Two pyroclastic flows that formed during the eruption, a smaller one at about 10:35 and a bigger one shortly before 11:00. They could have been caused by to the collapse of parts of the crater wall of the New SE crater.
The rise of activity has been gradual over several days, and while tremor peaked around midnight, then dropped a bit, the eruptive activity itself continued to increase and first peaked today:
- two phases of lava flows were produced, one at the end of the night and one at noon. The emergence of the lava flow caused a portion of the inner wall to collapse, which in turn produced the pyroclastic flows.
- strong single explosions merged into sustained lava fountains first during the early afternoon, after the tremor had started to decrease a bit. This activity was accompanied by a dense and tall plume of lapilli and ash, typical for Etna's paroxysms.

The eruption continued all night with strong strombolian explosions and the slow effusion of one or several lava flows from the eruptive fissure to the east. The explosions have been accompanied by loud bangs that rattled windows in many kilometers away and could be felt until the Ionian coast. The volcanic tremor has continued to rise to very high levels (as high as during the most powerful paroxysms of the past weeks) where it has now been stagnating for the past hours. This paroxysm has been quite different from most others: It seems that so far, no true lava fountaining has occurred, rather ongoing strong explosions at a duration that is truly amazing.

Maybe we are in for something different this time, or, more likely, the expected new paroxysm will take longer than the previous ones to build up.

However, this current behavior of Etna is a quite different from the usual more or less short build-up of activity the cone showed preceding the recent paroxysms. The tremor is slowly increasing.
It will be interesting to see what comes next, another paroxysm, or something different? Etna is always good for surprises!

New activity has started yesterday afternoon from the New SE crater. Several relatively intense explosive ash emissions were observed from the summit vent of the cone. They produced dense ash plumes rising about 200 m. More explosions occurred during the night, separated by intervals varying from 20 minutes to about 2 hours, during which strong degassing continued and the fumarolic area at the crater rim remained incandescent.
The tremor showed a light increase during the night, but it is not clear at the moment, if this is already a precursor to yet another paroxysm.

The paroxysm indeed took a while to reach a relatively long-lived peak phase with high lava fountains, after building up slowly with large explosions of bursting liquid lava bubbles.
Boris reports: "After a few hours of seeming a bit undecided whether to really let loose or not, Etna's New Southeast Crater finally did let loose, and blood-red lava fountains shot hundreds of meters into the blue Sicilian sky. Taken at 14:22 GMT (=local time -2) from Monte Vetore, about 6.4 km to the southwest."

The 9th paroxysm from the New SE crater in 2013 is occurring this afternoon. It seems it now has reached its peak phase with lava fountains, and lava flows from the fissure vent of the New SE cone descending into Valle del Bove. It seems that the fountains are much smaller ("only" 2-300 m) compared to those of the last eruption on 16 March, but the peak phase lasts longer this time.

Tremor at the New SE crater (ETFI signal, Torre del Filosofo station) continues to rise. It seems now almost Certain that a new paroxysm is in the making.
Rising tremor - begin of a new paroxysm?

The tremor has started to rise,- possibly this could be the begin of a new paroxysm at the New SE crater. Clouds in the summit area prevent direct view to confirm if any activity is occurring there at the moment.

More than 2 weeks have passed since the last eruption from the New SE crater and it seems more and more likely that something in the volcano's current eruptive behavior once again is about to change. Of course, it would also not come as a surprise if another paroxysm occurred in the near future.
Sandstone xenoliths from 16 Mar eruption:
Closer inspection of the "white lava" reported in yesterday's news revealed that these were so-called xenoliths, i.e. no lava at all, but pieces of sedimentary rock from strata underlying the volcano brought up by the rising magma. In this case, they are pieces of barely compacted beach sandstone, similar to the xenoliths ejected during the flank eruptions in 2011 and 2012, which are believed to have trapped a different (so-called eccentric) shallow magma chamber beneath the volcano. To find such xenoliths as produces of eruptions from the SUMMIT craters is highly unusual and could (*speculation*) indicate that the latest, violent, eruptive episode has actually involved a different magma reservoir as well.
Fresh snow has now covered much of the bombs from the recent eruption.
