Short update - Mt Etna, Sicily - 24.02.2025

Mt Etna is back in action!
During the night of 23 February, the emission of lava at the euptive fissure below Bocca Nuova intensified again. In the evening, strombolian activity was visible on the north-west flank of the old South East Crater cone and the lava flow appeared even better fed than in the early morning. At the same time, the tremor increased significantly and once again reached a high level. The eruptive activity continued unchanged on 24 February.

The volcanic tremor on Mount Etna has been dropping significantly for a few hours now. Is the eruption, which has been going on since 8 February, coming to an end?

Farewell you beautiful patch of nature!

I loved this area, called Galverina, with its green meadows, old rocks and flowering plants and always enjoyed visiting it. Today it has been largely destroyed by the lava flow of Mount Etna.

The mountain gives life and takes it away again...

Short update - Mt Etna, Sicily - 16.02.2025

Strong explosive activity at Mt Etna's Southeast Crater produced a lot of ash today. It travelled south/southeast and caused many flight cancellations at Catania International Airport. Meanwhile, the front of the lava flow is now moving at an altitude of about 1900 m in the Galvarina area, below Monte Pecoraro. It is not far from the forest track.

In this INGV photo, which was taken on the evening of 16 February from Piedimonte Etneo (north of Etna), you can see the ash clouds rising from the old area of the Southeast Crater and moving southeast in the left half of the photo. To the right is the Central Crater cone:

On 14 February, effusive activity continued at the southern base of the Central Crater cone. The lava flow on the south-west flank of the mountain has reached an elevation of approx. 1900 m in the Galvarina area and is approx. 3 km long. The tremor is still at a high level. Since 12 February, the old South-East Crater has been emitting strong and persistent ash and showed mild strombolian activity. A new vent, which had developed during the eruption on the upper north-western flank of the old South-East Crater, released steam, gas and some dark ash as well as occasionally some incandescent material from 11 February onwards.

This INGV webcam photo, taken on the evening of 13 February, shows the lava flow on the left, which flows down the southern flank in a south-westerly direction. The interaction with the snow cover produces a lot of water vapour, which is illuminated by the lava flow. On the right, a small strombolian explosion can be seen at the South-East Crater:

As reported by INGV, the emission of a lava flow was observed this evening at 18:35 at the south-eastern base of Mt Etna's summit crater Bocca Nuova. The lava flow originates from a point at an altitude of 3000 metres between Bocca Nuova and the Southeast Crater complex and is moving towards Monte Frumento Supino.
As further reported, mild explosive activity had already occurred temporarily at the Southeast Crater on 6 February. Today the tremor was at a medium level with fluctuations. The source of the tremor was below the Southeast Crater at an altitude of 2800 - 3000 metres. The infrasound activity was very low today, while it was moderate on the previous days and emanated from the Southeast Crater. Only a very small deformation of the volcanic edifice was measured (tenths of a microradian at Cratere del Piano station).

In this context, it is interesting to note that a new thermal anomaly was detected today during the overflight of the Sentinel-2 satellite. It was located on the upper eastern flank of Bocca Nuova. It is possible that a new vent has opened there that either only emitted hot gas or has developed into the effusive vent that feeds the new lava flow.

This INGV webcam photo from this evening shows the situation at the southern base of Bocca Nuova or the Central Crater cone. Two glowing areas can be seen in the left half of the image, which mark the course of the lava flow. The upper, more easterly section of the lava flow probably lies behind the lava fields of the South East Crater and is therefore presumably obscured:
