• Etna stop and go: it turns on and off continuously

• Stromboli, explosions from the Aeolian volcano.

  Fear on the island, no consequences.

Stromboli and Etna active at the same time.

The Etna Observatory of the National Institute of Geophysics and Volcanology, announces that the monitoring networks recorded a variation of the monitored parameters at 3.32 pm.

A landslide was identified from the seismic track and from the video surveillance cameras.

The surveillance system of the National Institute of Geophysics and Volcanology-Etna Observatory of Catania recorded on the Stromboli volcano, in the Aeolian Islands, an explosion at the North-East crater which triggered a landslide with the rolling of lava material that occurred 'detached from the altitude of 600 meters above sea level. At 3.28 pm, the Ingv detected a seismic signal lasting about two minutes, associated with the landslide event observed through the surveillance cameras. The amplitude of the tremor is at medium-low levels.

On the front of the largest of the volcanoes, from the images of the video surveillance cameras it is observed that the lava fountain from the south-east crater of Etna, ceased at 14.50, but the lava overflow directed to the south-west remains and continues to be fed . There is also a second lava flow produced by a second overflow of the south-east crater that spreads towards the Valle del Bove. The volcanic tremor, after reaching the maximum value at 14.20, suffered a rapid decrease returning to the average level. Currently this parameter shows a trend towards a further decrease. The center of the volcanic tremor sources remains located in the south-east crater area at an elevation of approximately 2,800 meters above sea level.  

The activity of Etna caused the emission of an eruptive cloud which turned into a 'rain' of lava ash that fell copiously over Catania. The eruption on Etna has not had any impact, at the moment, on the operation of the Fontanarossa airport in Catania.
