After a slightly longer interval than previously, a bit less than 3 days since the eruption on 12 March, Etna continued its impressive series of lava fountaining episodes known as paroxysms early this morning.

Already last night, from around 7 pm, first signs of reactivation of the New SE crater began to be visible in form of intermittent mild strombolian explosions.
Starting from around 1 am early this morning local time, this activity and volcanic tremor, sign of magma rising inside the conduits, started to increase significantly as typical for the beginning of Etna's paroxysms.
At around the same time, a lava flow started to issue from the eastern summit vent of the New SE crater and descend towards the Valle del Bove.
Strombolian activity increased rapidly to continuous lava fountains with several hundred meters height. As during the previous paroxysms, the lava flow quickly increased and expanded to a few km length reaching the Valle del Bove at elevations below 2000 m.
Activity reached a peak around 3 am, then abruptly decreased from 3:40 am.
This marks the 13th paroxysm of Etna since the start of the current series, which had started on 16 February. Since then, the volcano has been producing paroxysms almost with clockwork precision almost every 2-3 days, with only one exceptions of a significantly longer interval (the 4.5 days interval between 24 and 28 Feb episodes #6 and #7).
