The eruption caused the partial collapse of the crater terrace. This was followed by major flows of lava stretching to the sea and immense plumes of smoke rising several hundred meters above the volcano. Italian civil protection authorities raised the alert from yellow to orange as the ‘situation of enhanced volcano imbalance persists.’ This Sentinel-2 image (above) has been processed in true color, using the shortwave infrared channel to highlight the new flow of lava. Sentinel-2 is based on a constellation of two identical satellites, each carrying an innovative wide swath high-resolution multispectral imager with 13 spectral bands for monitoring changes in Earth’s land and vegetation. The northernmost island of the Aeolian archipelago, located just off the northern tip of Sicily, Stromboli’s volcano has been erupting almost continuously for the past 90 years.
