Strong Strombolian activity that started at Etna’s Voragine crater at 15:45 UTC on July 22, 2024, increased around 01:00 UTC on July 23 and evolved into a new lava fountaining episode at 02:59 UTC.
The eruption produced strong ash emissions, rising up to 4.6 km (15 000 feet) above sea level, according to Toulouse VAAC. In addition, INGV’s Etna Observatory reported that a lava overflow has started from the western rim of the Bocca Nuova crater.
From a seismic point of view, the average amplitude of the volcanic tremor has further increased with this activity. The sources of the tremor remained in the area of the Voragine crater at an elevation of approximately 3 000 m (9 800 feet) above sea level.

“There is a further increase in frequency of occurrence and amplitude of infrasonic events at the Voragine crater,” INGV-OE volcanologists said at 03:08 UTC. “The amplitude of the infrasonic tremor is increasing.”
“Starting from around 02:00 UTC, the clinometric network shows clear variations, more evident at the summit stations. The Monte Ruvolo dilatometer has accumulated a decompression equal to approximately 10 nanostrain.”
The Aviation Color Code was raised to Red at 20:44 UTC on July 22 and remains at Red at the time of press.
