Seismic trace of the 3.5 earthquake today (ESVO station, INGV Catania)
A shallow magnitude 3.5 earthquake occurred under the town of Zafferana, about 10 km east of the summit area this afternoon. ...more

After a long build-up phase of increasingly violent strombolian activity over several days, the 13th New SE crater paroxysm is occurring this evening. ...more
Saturday, Apr 20, 2013
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. ...more
Thursday, Apr 18, 2013
The 11th paroxysmal eruption from the New SE crater occurred as expected today. As during the previous eruption a week ago, the build-up phase with increasing strombolian activity was relatively long (about 2 days). 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 has now appeared at several vents on the fissure cutting through the New SE crater and the tremor signal is steeply rising, typical for the onset of another paroxysm.

A new paroxysm, the 10th such eruption in 2013, occurred today at Etna's New SE crater, after a several days-long phase of increasingly strong strombolian explosions. It culminated with lava flows and lava fountains and a tall ash plume. ...more
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. ...more

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. ...more

Today is a very sad day for all free people who like Etna: Etna has become a "forbidden volcano". ...more

As expected, Etna's New SE Crater produced a new episode of lava fountaining (paroxysm) on 3 April 2013. It was the 34th paroxysm since January 2011 at Etna and according to eyewitnesses, it was the loudest such eruption ever witnessed in recent years. "Especially toward the end, Etna thundered, growled, howled, yelled like a gigantic beast in agony. It almost hurt your ears at a distance of 6.4 km." ...more

The 9th paroxysmal eruption from Etna's New SE crater in 2013 has occurring this afternoon and is currently at its peak phase it seems. ...more
It seems almost certain that a new paroxysmal eruption is in the making at the New SE crater of Etna. Tremor has started to rise sharply and reached already 5 times background level. You can follow the events live at webcams.volcanodiscovery.com/Etna

White sandstone xenolith from the 16 Mar New SE paroxysm
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. ...more

Etna volcano might have begun a process of deep transformation in its eruption style, new scientific studies suggest. ...more

It seems that a new paroxysm is in the making. The tremor signal is showing a pronounced rise, typical for the beginning of the New SE crater paroxysms.
Wednesday, Mar 06, 2013
Another paroxysmal eruption (the 7th in a row this year so far) occurred from the New SE crater during the night. Following a period of increasing strombolian activity, large lava fountains were rising from vent in the saddle between the old and new SE crater as well its summit vent.
Tuesday, Mar 05, 2013
Strombolian activity from Voragine continued this night, and also ash eruptions from the New SE crater were seen this morning. This could be a precursor of a new paroxysm in a near future.

Saturday, Feb 23, 2013
The 5th paroxysm of the New SE crater is occurring. Tall lava fountains are erupting from the fissure vent of the New SE crater. This time, the eruption is much bigger than the previous ones. Judging from webcam images, lava fountains might be reaching one km in height.

Etna during the 3rd New SE crater paroxysm
3 peaks of the tremor amplitude represent the paroxysmal eruptions (INGV)
Etna had no less than 3 paroxysms (particularly violent brief eruptive episodes) with lava fountains, lava flows and tall ash plumes from the New SE crater within the past 20 hours (so far). ...more
Tuesday, Feb 19, 2013
What had started last night evolved into the first true paroxysmal eruption of 2013, marked by tall lava fountains and lava flows from the New SE crater.

Depth vs time of recent quakes under Etna.
Vigorous eruptive activity has started at the Bocca Nuova crater and at the time of updating, it is strongly increasing. Tremor has started a steep rise, typical for a paroxysm. ...more
Monday, Jan 28, 2013
A new eruptive phase has started at Bocca Nuova. Since this morning, small ash emissions have been observed and now at night, glow can be seen. The tremor signal has been rising as well.

After a brief period of activity at the Bocca Nuova crater, strombolian activity shifted to the New SE crater on the night of 22 January. This much stronger activity has continued into 23 January.
Thursday, Jan 17, 2013
Another brief, but probably strong eruptive phase - a small paroxysm - occurred last night at one of the summit craters, most likely Bocca Nuova.
Thursday, Jan 10, 2013
This night at around 1:00 am local time, eruptive activity, most likely strombolian eruptions from the eastern vent, resumed in the Bocca Nuova, accompanied by a rise in tremor. Images indicate that the activity gradually increased untiil about 3:15 and the stabilized.
