Ash emissions from the Planchón-Peteroa volcano
On 25 October 2025, the Planchón-Peteroa volcanic complex, located on the Chile–Argentina border, emitted a sustained plume of volcanic gas and fine ash that rose to approximately 600 m above the crater. The plume initially drifted north-north-west; however, shifting wind conditions during the day redirected the ash eastwards, carrying it over Argentine territory.
This image, acquired by one of the Copernicus Sentinel-2 satellites on 25 October 2025, shows the volcanic complex with a distinct ash plume extending eastwards from the summit area. Ash is clearly visible spreading across the snow-covered slopes and into Argentina.
The Copernicus Sentinel satellites provide crucial data on volcanic activity worldwide, supporting authorities and researchers with information on eruptions and their impacts on human activities.
