While all eyes are on Iceland waiting to erupt, it was a volcano from another European island that erupted on November 12, Etna, Italy. This activity, brief but very violent, was partly hidden by clouds, but it further enlarged the south-east crater: the summit of the highest active volcano in Europe therefore continues its rapid rise!

After the August panic, Etna remained fairly quiet. This was followed by a resumption of modest Strombolian activity at the southeast crater in October, the most active of Etna’s four summit craters and its summit for several months. Then, this activity intensified from October 22, when eruptions became slightly stronger and more frequent, even though the eruptions fell mainly inside this volcanic cone.

It was on 12 November that explosive activity increased markedly, producing lava fountains several hundred meters high, which produced an ash column at least 1,500 meters high, which was blown eastward by the wind. Thus some ash fell in the villages east of the volcano…
Some pictures of the panic behind the clouds…
This westerly wind also brought many clouds which made it impossible to see the activity clearly, even though the incandescent rays reflected there and some burning showers, which could still be distinguished at intervals, did make the activity Left no doubt about the violence!

A little later, images obtained from cameras or satellites indicate that lava flows also occurred during this event, from a notch that bisects the southern slope of Southeast Crater. Like previous paroxysms, they engulfed the ancient eruptive cones that lie south of this volcanic cone, and traveled between 1 and 1.5 kilometers from its base. Furthermore, if the collapse of part of this south-east crater has been observed, it seems to have grown even larger: hence the summit of Etna is constantly rising!
