English: At 11:24 AM local time on 2 June 2025, Mount Etna, the most active volcano in Europe, produced a spectacular eruption, propelling a dense column of ash and smoke several kilometres into the atmosphere. The event was characterised by vigorous Strombolian activity, lava effusion, and a pyroclastic flow. According to Italy’s National Institute of Geophysics and Volcanology (INGV), the eruption originated from the South East Crater, one of the most active summit vents in recent years. The Copernicus Sentinel-2C satellite acquired an image of the area at 09:40 UTC, just minutes after the onset of the eruption. On the left, the natural colour image clearly depicts a dense ash plume in the summit crater area, partially obscured by a pyrocumulus cloud drifting westward towards inland Sicily. On the right, a false colour composite using shortwave infrared channels reveals the intense thermal signature of active lava flows descending into the Valle del Bove. Copernicus data is key to tracking global volcanic activity, helping communities to assess hazards, support emergency response operations, and monitor long-term changes to landscapes.
