Image Caption: ISS013-E-62714 (2 Aug. 2006) --- Mt. Etna Summit Plumes, Sicily is featured in this image photographed by an Expedition 13 crewmember on the International Space Station. One of the most consistently active volcanoes in the world is Sicily's Mt. Etna, which has a historical record of eruptions dating back to 1500 B.C. This image captures plumes of steam and possible minor ash originating from summit craters on the mountain -- the Northeast Crater and Central Crater, which includes two secondary craters (Voragine and Bocca Nuova). Explosions were heard from the rim of the Northeast Crater on July 26, and scientists suspect that these plumes are a continuation of that activity. The massive 3350 meter high volcano is located approximately 24 kilometers to the north of Catania, the second largest city in Sicily, and dominates the northern skyline. Much of Etna's surface is comprised of numerous generations of dark basaltic lava flows, as can be seen extended outwards from the summit craters. Fertile soils developed on older flows are marked by green vegetation. While the current explosive eruptions of Etna tend to occur at the summit, lava flows generally erupt through fissures lower down on the flanks of the volcano. Many of the lava flow vents are marked by cinder cones on the flanks of Mt. Etna. Scientists have noted evidence of larger eruptive events as well. The Valle Del Bove to the south-southeast of the summit is a caldera formed by the emptying of a subsurface magma chamber during a large eruptive event -- once the magma chamber was emptied, the overlaying roof material collapsed downwards.
