Summary edit
DescriptionNew effusive activity of Etna volcano, Italy.jpg |
English: Etna is one of the most active volcanoes in Europe. In the evening of 13 December 2020, a rapid intensification of the activity at one of the summit craters (the one named as South East Crater) was observed: this activity produced pyroclastic flows and ash emissions in the following days. On 15 October, the Copernicus Sentinel-2 and Copernicus Sentinel-3 satellites have provided two different acquisitions over the summit of Etna volcano with a temporal separation of 27 minutes. This image is composed using the large view retrieved by the Copernicus Sentinel-3 satellite (left) and the zoomed view of the Copernicus Sentinel-2 satellite (right): both the ash plume extending along the south-eastern coast of Sicily and the lava flow effusing along the southwestern side of the summit craters are visible. The Copernicus Sentinel-2 satellites play an important role in volcanic activity monitoring thanks to the Short Wave InfraRed channels of the Multispectral Instrument. The high spatial resolution and an average revisit time of five days allow them to monitor different volcanic processes and improve hot-spot detection techniques. |
