Comment for this article and video
On the evening of 28 September 2011, the New Southeast Crater of Etna has produced its 15th paroxysmal eruptive episode since the beginning of this year. The culminating phase of this episode lasted less than a half hour but was more violent than those of the preceding paroxysms; on the contrary lava emission was rather minor, forming two small flows that reached the upper part of the steep western slope of the Valle del Bove. The ash plume was driven southwestward by the wind.

Etna Information
Mount Etna, towering above Catania, Sicily’s second largest city, has one of the world’s longest documented records of historical volcanism, dating back to 1500 BC.
Historical lava flows cover much of the surface of this massive basaltic stratovolcano, the highest and most voluminous in Italy. Two styles of eruptive activity typically occur at Etna. Persistent explosive eruptions, sometimes with minor lava emissions, take place from one or more of the three prominent summit craters, the Central Crater, NE Crater, and SE Crater. Flank eruptions, typically with higher effusion rates, occur less frequently and originate from fissures that open progressively downward from near the summit. A period of more intense intermittent explosive eruptions from Etna’s summit craters began in 1995. The active volcano is monitored by the Instituto Nazionale di Geofisica e Volcanologia (INGV) in Catania.
