Etna: new eruptive activitySeptember 8, 2011
Eruptive activity stopped in the afternoon
From 8 a.m. of September 8, Ingv monitoring networks - Catania section - registered a resumption of Etna volcanic activity from the pit crater, at the base of the south east crater, as showed by a significant increase of some monitored parameters.
The activity was featured by a significant emission of volcanic ash, started at 8.45 a.m. and finished a couple hours later, reaching a height of some 8,000 meters a.b.l., with lava fountains and a small lava spill that developed at the base of the south-east crater and stayed isolated in the top area of the volcano.
Based on observations of volcanic phenomena, the Central Functional Centre - Volcanic Risk sector - of the Civil Protection Department issued a notice of "high criticality" for the top area of the volcano and "ordinary criticality" for the middle, foot of the mountain and urban areas.
Eruptive activity stopped around 5 p.m. today, 8 September, as signalled by the National Institute of Geophysics and Volcanology - Section of Catania.
The Regional Operating Room signalled a small volcanic ash fall in the municipality of Trecastagni.
The total ban of accessing the volcano over 2.920 m is extended to 23 September 2011 - in proximity of the Philosopher's Tower and Punta Lucia - , either on the North and South side, according to the ordinance of the Prefect of Catania.
The Central Functional Centre continues the surveillance activity of the phenomenon through its Ingv competence centres in Catania and University of Florence an through the operating structures of the Alpine Rescue of Guardia di Finanza and Forest Corps of Sicily Region, and territorial presidia.
