Etna volcan
Stratovolcan complexe Currently about 3329 m (changing due to eruptive activity and collapse of its crater rims)
Sicile (Italie), 37.75°N / 14.99°E
Condition actuelle: en éruption (4 sur 5) 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

Once more, Etna produced a very impressive show of unsurpassed fireworks at night: The - awaited - 5th lava fountaining episode (known as paroxysm) occurred late at night and turned out to be particular violent, equal or even stronger than the previous one 48 hours earlier. It was the 5th in a row during a single week's time!

The events building up to the eruption were quite typical and similar to the previous paroxysms: at first, the until-then intermittent and mild strombolian activity from the New SE crater gradually picked up, starting from around 10 pm local time. At the same time, volcanic tremor started to show a steep increase, sign of magma moving upwards inside the volcano's conduits.
The activity began to turn into sustained lava fountains from around midnight, and continued to increase in intensity. Around 00:30, the activity reached its peak phase with very tall lava fountains surpassing 1000 m height! An impressive eruption column of ash and steam rose to probably more than 10 km altitude and spread into an impressive, near-circular umbrella cloud towering over eastern Sicily.
At around 1:05 am, activity quickly ceased, with a phase of reactivation during approx. 4.40 and 6 am, when a series of strong explosions occurred at the SE crater complex.
Similarly to the previous events, lava flows were erupted to the SW and the east of the New SE crater into Valle del Bove, reaching similar lengths as before.

Intense strombolian activity at the eastern vent of the New SE crater
Yet another phase of lava fountaining, or paroxysms, is almost certainly about to start now. Volcanic tremor has started to rise sharply from low to now already high levels, and strombolian activity at the eastern vent of the New SE crater is becoming more and more intense and near-continuous. ... lire toutes

Last night's eruptive episode of tall lava fountains, known as paroxysm, turned out to be one of the most impressive and powerful in recent years. Not only did it produce higher fire fountains than usually, but also it lasted longer than most other paroxysms. ... lire toutes

The 4th paroxysm within little more than 4 days is occurring at the time of this update! Starting in the evening of 20 Feb 2021, the explosive activity at the New SE crater gradually increased and developed into sustained lava fountains now approx. 300 m tall, and still rising. ... lire toutes
