When and how the eruption occurred
On June 2, 2025, Mount Etna — located on the eastern coast of Sicily — experienced a sudden and powerful eruption. According to scientists from the Etna Observatory (INGV), a massive column of ash, gas, and volcanic material rose to approximately 6.5 kilometers above the summit, significantly exceeding Etna’s usual background activity.
The eruption was classified as strong Strombolian activity, involving violent explosions, lava fountains, and the emission of pyroclastic material. The event was triggered by a partial collapse of the southeastern crater sector, which released pressure and caused the explosive phase of the eruption.
🌋
Scale and nature of the phenomenon
- The ash and gas plume was visible from cities located tens of kilometers away.
- Seismic instruments recorded increased volcanic tremor, typical of major eruptive episodes.
- Lava flows descended along Etna’s slopes but did not reach densely populated areas, preventing major structural damage.

Italian Civil Protection response
🚨
Warnings for residents and tourists
The Italian Department of Civil Protection, working in coordination with the National Institute of Geophysics and Volcanology (INGV), immediately activated alert procedures.
Actions included:
- Closure of summit zones and permanent danger areas;
- Official recommendations to stay away from high-altitude regions of the volcano;
- Continuous public updates via emergency communication channels.

Impact on aviation
Due to large quantities of volcanic ash in the atmosphere, aviation authorities issued a red aviation alert. This is a standard safety procedure designed to protect aircraft engines from ash ingestion. Air traffic near Catania Airport was temporarily restricted and closely monitored.

Monitoring and preventive measures
Italian Civil Protection and INGV carried out:
- Continuous seismic, geodetic, and gas-emission monitoring;
- Live data transmission from thermal cameras and satellite systems;
- Ongoing coordination between regional and national emergency units.
These measures aim not only to respond to eruptions but also to anticipate further escalation in volcanic activity.

Consequences of the eruption
🧑🤝🧑
Impact on population
- No fatalities or serious injuries were reported.
- Local communities are well accustomed to volcanic risk, allowing for calm and orderly reactions without large-scale evacuations.

Environmental and infrastructural effects
- Volcanic ash temporarily affected air quality in nearby towns.
- Agricultural areas experienced minor ash deposition.
- Road and air traffic disruptions were short-term and controlled.
