| Ash Plume Streams from Mt. Etna, Sicily: When this
southward-looking photograph was taken by the Expedition 2 crew
aboard the International Space Station, the city of Catania (in
shadow, ~25 km SSE of the volcano) was covered by a layer of ash and
Fontanarossa International Airport was closed. On that day an ash
cloud was reported to have reached a maximum height of ~5.2 km.
Plumes from two sources are visible here—a dense, darker mass from
one of the three summit craters and a lighter, lower one. The record of historical volcanism of Mt. Etna is one of the longest in the world, dating back to 1500 BC. Two styles of activity are typical: explosive eruptions, sometimes with minor lava flows, from the summit craters and flank eruptions from fissures.
