Short update - Mt Etna, Sicily - 29.03.2025

In the last 14 days, further Strombolian episodes have occurred at the South East Crater of Mt Etna:
Accompanied by strongly increasing tremor, weak Strombolian explosions were visible at the former saddle vent of the South East Crater on the evening of 19 March. The vent located above the large southern breach continued to increase its activity until midnight and finally powerful Strombolian explosions hurled glowing material onto the southern and eastern flanks of the New South East Crater cone. Further vents on the upper north-west flank of the cone also became active. After about 02:30 the intensity of the explosions decreased again and at sunrise the activity was already significantly reduced.
A similar episode began on the morning of 24 March, but it took place in very bad weather. The fading Strombolian activity at the South East Crater could only be observed in the evening.
Another Strombolian episode is likely to have occurred on 28 March, as the tremor again increased sharply for a few hours, but dense clouds and fresh snow prevented any observation via webcams.

After almost 14 days of quiet gas emission at the summit craters, mild Strombolian activity suddenly began at Mt Etna's South East Crater on the evening of 15 March. During the night of 16 March, the activity increased significantly and there were some powerful Strombolian explosions. The event was accompanied by rapidly increasing tremor. On 16 March, the tremor fell back to a medium level and the eruptive activity came to an end.

This INGV-webcam photo from the late evening of 15 March shows the strombolian activity at the South East Crater. The vent, which is located above the large southern breach, throws the glowing pyroclastic material about 100 metres upwards. Individual bombs reach the south-eastern base of the cone (lower right half of the image):

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?

Short update - Mt Etna, Sicily - 31.12.24

Since mid-November, there has been calm gas emission at the summit craters of Mt Etna, which is mainly concentrated on the Voragine and the New South East Crater.

Previously, the 7th paroxysm of 2024 had occurred at Voragine on 10 November. The summit crater produced lava fountains during very bad weather conditions and released a short lava flow. Ash fell on the villages on the eastern flank of Mt Etna. In July and August, the paroxysmal episodes of the Voragine produced lava fountains up to 1000 metres high and the ash rain led to the closure of Catania's international airport on several occasions. A new intracrater cone grew in the Voragine and the lava flows buried the crater of the Bocca Nuova and flowed down the south-western to western flank of the Central Crater cone. As a result of this violent activity, the Voragine grew in height and became the highest point of the mountain at 3404 metres.

This INGV webcam photo from the morning of 26 December shows the New South East Crater in the centre of the image, which continues to emit gas. To the right above the South East Crater, you can see the Voragine, which continues to emit gas. To the right is the Northeast Crater, which is currently emitting a white vapour cloud:

During the first few days of July, the Strombolian activity in Etna's Voragine summit crater continued to intensify and the tremor reached a high level. On 4 July, the activity increased to the emission of lava fountains, which generated a high eruption column. Ash fell on the south-east flank of Etna and also reached the city Catania. Activity in the Voragine ended in the early hours of 5 July.
On 6 July, mild Strombolian activity began again in the Voragine. During the night of 7 July, this increased to the release of lava fountains. The eruption column was bent to the east and there was rain of ash from Zafferana to Giarre. At the same time, a lava flow was emitted from the summit crater Bocca Nuova, which flowed down the Central Crater cone in a westerly direction. The paroxysm ended in the morning, but there were further ash emissions until the evening.

Some pictures I took in the morning on the south flank at 1900 m...

Here some Pictures I took on 03 - 04/07/24 on Stromboli, where eruptive activity was unusualy high and generated ash clouds, ash rain on the villages and pyroclastic flows in to the ocean.
