Etna volcano, Italy - update

Wednesday Jul 13, 2005 16:00 PM | BY: TOM PFEIFFER

A visit of the VolcanoDiscovery group on Etna's summit craters found no visible activity from any of the summit craters and no fresh deposits of activity in the recent past.


The W and E vents inside the Bocca Nuova crater are about 50 and 30 m deep and there is a lot of debris from recent collapse of the vertical crater walls. The craters themselves appear to be completely sealed. Diffuse degassing was strong from the W vent and weak from the E vent. It is likely that further collapses will occur here in the future and one should be aware of the possibility of sudden phreatic explosions that might clear the vents when the expected future summit activity from the Bocca Nuova resumes, which has now been inactive for more than 4 years.
The two pits inside the Voragine crater were barely visible, and emitting large amounts of gas and steam. The rim of the NE crater is highly fractured and the crater floor could not be seen. The SE crater, which had been breached by a large collapse pit to the E side, about 100 m wide, appears also to have highly unstable walls, where strong fumaroic activity takes place. Deep inside the central crater of the SE crater, a seal of fresh black lava has been reported, probably originating from some weak strombolian activity in January/February.
