Explosive eruption at Etna volcano sends ash to 11 000 m (36 100 feet) a.s.l., Italy

Volcanic ash from Etna volcano in Italy was observed at 11 000 m (36 100 feet) above sea level at 15:00 UTC on December 27, 2025. The advisory was issued by Toulouse VAAC at 15:13 UTC.

The ash cloud was observed between the surface and flight level 360, corresponding to an altitude of up to 11 000 m (36 100 feet). The ash plume moved west at a speed of 46 km/h (29 mph). The event was classified with an Aviation Color Code Red. The advisory noted the plume was dark and clearly identifiable from the crater, with an earlier plume still visible on satellite imagery, primarily composed of sulfur dioxide. No forecast ash cloud beyond 6 hours was provided in this advisory.

The most recent Smithsonian/USGS Weekly Volcanic Activity Report does not mention Etna, so no further details on its ongoing activity are available in the current summary.

Etna is a large stratovolcano located on the east coast of Sicily, near the city of Catania, which is just 30 km (19 miles) away. The volcano is known for frequent explosive eruptions, lava flows, ashfall, and pyroclastic flows. Hazards include tephra fallout affecting air traffic and populated areas, as well as potential lava flows threatening nearby settlements.
