Sicily’s massive Etna Volcano is again showing signs of life after a 4 month pause, as NASA Earth Observatory is reporting. "Beginning on September 3, 2013, the Osservatorio Etneo (Etna Observatory) observed explosions and puffs of ash at the summit craters and New Southeast Crater. Over the next few weeks explosions became more frequent. Boris Behncke, a volcanologist at the Osservatorio Etneo captured photographs of ash plumes on September 23 and 25."
NASA's Landsat 8 captured an image of Etna's activities on 24 September 2013 showing a plume of what probably are volcanic gases moving in a southwestern direction.
