Eruptions du volcan Etna:
En activité quasi permanente ; certaines grandes éruptions historiques telles que : en 122 BC (éruption explosive du sommet), AD 1669 (éruption sur le flanc sud dévastatrice), 1787 (l'une des plus spectaculaires éruptions au sommet enregistrée - fontaines de lave, semble-t-il, jusqu'à 3000 m de haut).
Les éruptions depuis 1950 (f: flanc / s: activité sommitale): 1950-51(f), 1952(s), 1953(s?), 1955-64(s), 1966-1970(s), 1966(f), 1971(f), 1971-1980(s), 1974(f), 1978(f), 1979(f), 1980-81(s), 1981 (f), 1983(f), 1984(s), 1985(f), 1986(s), 1987(f), 1987(s), 1989(f), 1989-1991(s), 1991-93(f), 1995-2001(s), 2001(f), 2002(s), 2002-03(f), 2004-2005 (f),2006(s),2007(s),2008-9(f)
Style éruptif tipique:
Effusive (coulée de lave et fontaine de lave) et explosive avec des éruptions modérées stromboliennes et parfois phréatomagmatiques. Les deux types d’activités éruptives ont lieu fréquemment au sommet et sur ses flancs. Ses éruptions latérales au niveau des flancs, semblent se regrouper sur des laps de temps d’environs quelques dizaines d’années

Etna volcano update: Decreasing activity for now, but this could change soon

The decreasing trend in surface and earthquake activity on and around Etna continues and there is little to nothing left of the vigorous flank eruption that had started on Christmas Eve (24 Dec 2018). However, the volcano is far from quiet and there are indications that more and potentially more dangerous activity could be in the making.

A tell-tale sign that the flank eruption could only be a prelude is that magma continues to stand high inside the volcano's conduit: glow and intense gas and steam emissions are visible from the Bocca Nuova, producing a tall plume rising vertically into the evening sky. The recent eruption has drained only very little of the available magma. Will more come out soon?

Eugenio Priviera, director of INGV (the National Institute of Geology and Volcanology) mentioned in an interview quoted in a Sicilian newspaper that new eruptive fissures could open up even at lower altitudes. INGV posted a special report about the current situation and the recent earthquakes on its blog site:
Even though the current surface phenomena are weakening, the general decrease in eruptive activity could be misleading: information obtained from geophysical cannot exclude that magma supply into the same dike that fed the recent eruption is still in progress, and could open its way with new fissures down to altitudes beneath 2,400 m, especially in the area of the southern and western walls of Valle del Bove.

In the newspaper article mentioned, Priviera explains that one area particularly at risk for this could be the area of ​​Piano del Vescovo south of Valle del Bove in the SE sector of Etna. Whether this will happen or not cannot be predicted. According to the newspaper, Priviera said that the recent earthquakes have shown that the known Fiandaca fault was activated, which is a potentially dangerous situation. He announced that ground deformation monitoring is being intensified in the area.

Yesterday's destructive M4.8 earthquake that hit the lower SE flank of Etna t 03:19 local time (26 Dec) occurred 1 km S of Lavinaio (CT) village and caused lots of damage to houses and buildings. Its depth was localized to be at only 1 km below sea level (i.e. approx. 1500 m below the surface).
The quake coincided with the 3rd day of the eruption of Etna. INGV writes that "it should be noted that the earthquake was not generated by movements of magma masses present in the epicentral area, but probably was the response of the eastern flank of the volcano to a stress induced by the magmatic system that at that time fed the eruption."
In other words, the pressure induced by rising magma in the central conduit might have been the trigger to activate the fault lines on the eastern flank, but are likely not a sign that magma was intruding in the same area of the quake (at the lower eastern flank).
