MOUNT ETNA, active vulcano
Mount Etna is a complex stratovolcano which towers 3340m over the city of Catania on the Mediterranean Island of Sicily. The volcano has been frequently active in recent times and shows a combination of mild explosive activity, sometimes producing sustained ash columns, together with frequent A'a type lava flows which may reach runouts of several km. Spectacular paroxysmic lava fountaining events have been frequently observed at the summit craters in recent years.
The summit complex consists of a main structure with two adjacent craters (Voragine and Bocca Nuova), a NE crater and the large SE crater which was rapidly approaching the height of the summit craters until activity shifted to a vent on its E flank, now known as SEC-E (or SEC-2). The SE crater is located at the top of the Valle del Bove and numerous lava flows from the crater have entered this depression in recent years. All of the summit craters have been active in recent times.
