Stromboli volcano (Italy), activity update: lava flow still active

Tuesday Mar 06, 2007 09:54 AM | BY: TOM PFEIFFER

The lava flow is still very active at Stromboli volcano.
As observed from location, the summit craters and the adjacent areas to the NE have undergone significant collapse. The NE crater is now breached by a V-shaped incision and the flat area of the 2003 lava flows has sunk by around 20-50m as measured by radar (INGV). From the originally two vents of the current eruption, located along a fissure that cuts the craters, the pianorolo (the flat area east below the summit craters, where the vents of the 2003 effusive eruption were located) and part of the Sciara del Fuoco, only the lower one at about 400 m a.s.l. is still active. It feeds a well-channeled lava flow that branches into two arms that reach the sea at the eastern end of the Sciara del Fuoco.
At the sea, the new lava has formed a large delta, about 200 m wide and streching 50-100m into the sea from the old shoreline. A vigorous steam plume is originating from the entry points which are well visible from various viewpoints along the lower rims of the Sciara del Fuoco. Occasionally, phreatic explosions were visible at the entry point on 4 March. Large numbers of rockfalls, mostly some 100s meters W of the lava flows are occurring on the Sciara del Fuoco.
Access to the area is restricted by the Protezione Civile (Civil Defense unit); the area is still open for visitors to a maximum of 400 m, but it is planned to restrict access to the area of the Punta Labronzo at around 100 m a.s.l., above which further access will only be allowed with authorized mountain guides.
