The volcano is again in a phase with very regular rhythmic eruptive behavior, as short, but violent lava fountaining episodes (paroxysms) continue to occur from the New SE crater at intervals of approx. 36-48 hours, with little to no activity in the times between.

The latest ones happened Saturday evening (19 June 2021) between 20:45-21:30 local time and this night between around midnight to 1:45 am this morning.
In both cases, strombolian activity started to reappear about an hour before the lava fountaining phase, then quickly intensified to merge into fountains, which abruptly ceased after reaching their peak phase with heights of several hundred meters.

New lava flows were erupted in both cases from the southern part of the cone towards the SW into the Torre del Filosofo area, which is becoming a thick shield of overlapping recent lava flows.

This behavior is well reflected by the sharp spikes in volcanic tremor that separate quiet, recharging phases during the intervals.
