Violent lava fountaining startet at Etna volcano

A phase of violent lava fountaining started at Etna’s Voragine crater during the afternoon hours (UTC) of July 4, 2024. At the same time, significantly increased activity is being observed at Stromboli volcano.

Strombolian activity that started on June 13 – 14, 2024, at Etna’s Voragine crater slowly intensified over the past few days and has intensified significantly in the late morning (LT) of July 4.

This activity was accompanied by two lava flows, which began in the previous days, produced by two mouths placed respectively on the south-eastern side and on the north-western side of the debris cone inside the crater, INGV volcanologists reported at 14:20 UTC today.

This activity evolved into an intense lava fountaining (paroxysm), producing ash column up to 4.5 km (14 700 feet) a.s.l, INGV reported at 16:17 UTC.

The Aviation Color Code was raised to Red at 15:31 UTC. Ash cloud was observed drifting SE and ashfall was reported on the volcano’s SE flank and up to Catania.

Interestingly, Stromboli volcano is also exhibiting significantly increased activity today. Its Aviation Color Code was raised to Red at 15:43 UTC.

Red alert at Stromboli volcano after increased activity, large pyroclastic flows, Italy

A gradual increase in activity was observed at Stromboli volcano starting at around 17:30 UTC on July 3, 2024. By July 4, a new lava flow and pyroclastic flows were recorded, reaching the coastline and spreading into the sea. At 18:00 UTC, the Department of Civil Protection raised the alert level for the volcano from Orange to Red and transitioned to the pre-alarm operational phase.

A gradual increase in activity was observed at Stromboli volcano at around 17:30 UTC on July 3. This activity further increased at around 18:20, reaching the most energetic seismicity at around 18:40 UTC.

At 18:46, a flow of incandescent material was recorded, quickly spreading along the Sciara del Fuoco, reaching the coastline, and flowing into the sea.

A new well-fed lava flow from the North crater area was observed starting at 14:10 UTC on July 4. This flow was produced by a mouth at an altitude of 700 m (2 300 feet) above sea level, spreading along the Sciara del Fuoco. The phenomenon resulted in the formation of pyroclastic flows and the rolling of lava material up to the coastline.

Strong ash emissions, new lava fountaining episode at Etna volcano, Italy

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.”
