Etna volcano (Italy), activity update: new explosive activity at SE, collapse on flank of SE cone, new eruptive fracture SE of SE crater near Belvedere

Thursday Nov 16, 2006 16:37 PM | DOOR: TOM PFEIFFER

After its explosive phases on 9 Nov and 10-11 Nov, Etna had been relatively quiet over the past days. This changed again dramatically today (16 Nov):

A new explosive and effusive phase started at around 6 am local time, when tremor level rose and SE crater started strombolian activity quickly changing from weak to strong intensity.
From around 9:20 am, an dense ash plumes were again observed from SE crater drifting to the ENE at around 4000 m a.s.l. As it turned out, they were caused by large collapses on the S-SE flank of the cone, causing small debris flows covering the aera E-SE at the base of the cone.
In th area of collapse, near Belvedere, a new effusive vent also had opened. Its flows have cut the paths leading to the 2800 m vent The new flow is directed into Valle del Bove.
A small new lava flow emerged from the 3050 vent, which had last been active during the previous two episodes from 9-11 Nov.
At 9:45 local time, the 3050 m vents in the lower flank of Bocca Nuova became active again as well and a new lava flow started from here, overlapping those already cooling from the previous episodes. At the beginning, this activity was again accompanied by spattering from the vent(s).
The 2800 m vent (seemingly independant from all other activities) continues to emit a more or less stable lava flow that continues inside its tube until about 2400 m elevation in the upper Valle del Bove near the Monti Centinari.

Due to lack of participants, we decided to cancel the tour to North Sulawesi and postpone it to 2007. As an interesting alternative, we can offer a special trekking tour in Java and Bali from 5-20 August instead. There are two open spaces available.
