Etna update, 18 November 2013, 08:30 GMT

After the conclusion of the paroxysmal eruptive episode at Etna's New Southeast Crater in the morning of 17 November 2013, mild Strombolian activity continued until the late evening; after nightfall, a small lava flow was seen to issue from an effusive vent located on the lower eastern flank of the New Southeast Crater cone. This lava flow appears to be still active with its front about 1 km from the source, though the effusion rate is rather low. Bad weather is frequently hampering visual observation of the activity by means of the network of surveillance cameras; the volcanic tremor amplitude remains at relatively low levels, and no explosive activity is evident during the intervals of good visibility.

Etna update, 17 November 2013, 17:30 GMT

In the early morning hours of 17 November 2013, a new paroxysmal eruptive episode occurred at Etna's New Southeast Crater. This episode, which came less than six days after the previous paroxysm, was characterized by violent Strombolian activity and pulsating lava fountains, emission of lava flows toward south, east-southeast and northeast, and the formation of an eruption column charged with pyroclastic material that was blown by the wind toward northeast. As its predecessors, this episode ended with a long series of powerful explosions and loud bangs heard tens of kilometers away. The lava flows toward south and northeast are considerably less extensive than those emitted during the 11 November 2013 paroxysm. On the evening of 17 November 2013, Strombolian activity a the New Southeast Crater is again intensifying. Further updates will be provided as the situation evolves.
