On October 28, 2002, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this true-color image of the ongoing eruption of Europe’s largest and most active volcano, Mt. Etna, on the island of Sicily. The volcano’s thermal signature was detected by MODIS and is marked with a red overlay. On the northern slopes of the volcano, the thermal signature is possibly a second lava flow. A dense plume of what is likely ash and smoke is streaming southward from the volcano and out over the Mediterranean Sea.
