Italy’s Mt. Etna unleashed a spasm of volcanic activity on April 10, 2011. Ash, lava, and gas were all released from the episode which lasted through the course of the day.
One of the most consistently active volcanoes in the world, Sicily’s Mount Etna has a historical record of eruptions dating back to 1500 BC. This astronaut photograph captures plumes of steam and possibly ash originating from summit craters on the mountain: the Northeast Crater and Central Crater, which includes two secondary craters (Voragine and Bocca Nuova).
