Yesterday evening, activity at the volcano increased quickly into another phase of lava fountaining, known as paroxysm, from the New SE crater.

It followed the slow effusion of a lava flow from the same vent that had started in the morning. It is thought that the lava effusion during the da preceding the eruption at night was the result of fresh, gas-rich magma rising in the conduits, and pushing the older, largely degassed magma out first, which would explain the lava effusion.
The peak of the intense eruptive phase was around 9:30 pm local time. The eruption produced a tall ash column that rose to 4000 m altitude and drifted south and southeast. The Ash Advisory Center of Toulouse relayed reports of ash falls in the village of Fleri on the SE side of Etna.
The event also generated several lava flows from the New SE crater that descended to the south and east of it, reaching the Valle del Bove depression. The paroxysm ended at around 10 pm.
Lesser ash emissions continued throughout the night and today.
Last night's eruption marks the 4th paroxysm in a new series that had started on 13 Dec last year.
