The activity at the New SE crater has been increasing, with dense ash columns rising to estimated 20,000 / 6 km altitude or more. At the same time, volcanic tremor has been increasing as well. It looks likely that the volcano is about to produce another lava fountaining-phase, known as paroxysm from its most active summit vent.

It is unclear at the moment whether the lava effusion from the small fissure vent in the Valle del Bove that had opened yesterday still continues.

It had been modestly active throughout the night, producing a small lava flow, but there was no sign of explosive activity. Volcanologists interpreted it as old (degassed) magma from the conduit leading towards the summit vents, that had simply "leaked" through a small lateral fissure. No inflation or particular seismic signals that would be typical for larger flank eruptions involving new magma had been detected accompanying it.
